text: The pair is a non-eclipsing binary—that is, as seen from Earth, neither star passes in front of the other.  The two components orbit each other at a distance of around 100 million km and an orbital period of approximately 104 days.  The stars were probably of spectral class A during their main-sequence lifetime, similar to Vega; they are now expanding, cooling, and brightening to become red giants, a process that will take a few million years.  It is thought that the more massive star of the pair has begun fusing helium to carbon and oxygen at its center, a process that has not yet begun for the less massive star.

text: The center of the nebula, not having much angular momentum, collapsed rapidly, the compression heating it until nuclear fusion of hydrogen into helium began. After more contraction, a T Tauri star ignited and evolved into the Sun. Meanwhile, in the outer part of the nebula gravity caused matter to condense around density perturbations and dust particles, and the rest of the protoplanetary disk began separating into rings. In a process known as runaway accretion, successively larger fragments of dust and debris clumped together to form planets. Earth formed in this manner about 4.54 billion years ago (with an uncertainty of 1%) and was largely completed within 10–20 million years. The solar wind of the newly formed T Tauri star cleared out most of the material in the disk that had not already condensed into larger bodies. The same process is expected to produce accretion disks around virtually all newly forming stars in the universe, some of which yield planets.

text: Supergiants develop when massive main-sequence stars run out of hydrogen in their cores.  They then start to expand, just like lower-mass stars, but unlike lower-mass stars, they begin to fuse helium in the core smoothly and not long after exhausting their hydrogen.  This means that they do not increase their luminosity as dramatically as lower-mass stars and they progress nearly horizontally across the HR diagram to become red supergiants.  Also unlike lower-mass stars, red supergiants are massive enough to fuse elements heavier than helium, so they do not puff off their atmospheres as planetary nebulae after a period of hydrogen and helium shell burning.  Instead they continue to burn heavier elements in their cores until they collapse.  They cannot lose enough mass to form a white dwarf, so will leave behind a neutron star or black hole remnant, usually after a core collapse supernova explosion.

Writer Melissa Robbie concurs, stating that some movies are high-concept (i.e. they have what Epstein terms "hooks") whereas others are simply star vehicles for bankable stars.

text: Barnard's Star's has 10–32% of the solar metallicity. Metallicity is the proportion of stellar mass made up of elements heavier than helium and helps classify stars relative to the galactic population. Barnard's Star seems to be typical of the old, red dwarf population II stars, yet these are also generally metal-poor halo stars. While sub-solar, Barnard's Star's metallicity is higher than that of a halo star and is in keeping with the low end of the metal-rich disk star range; this, plus its high space motion, have led to the designation "intermediate population II star", between a halo and disk star.

text: All red supergiants will exhaust the helium in their cores within one or two million years and then start to burn carbon.  This continues with fusion of heavier elements until an iron core builds up, which then inevitably collapses to produce a supernova.  The time from the onset of carbon fusion until core collapse is no more than a few thousand years.  In most cases, core collapse occurs while the star is still a red supergiant, the large remaining hydrogen-rich atmosphere is ejected, and this produces a type II supernova spectrum.  The opacity of this ejected hydrogen decreases as it cools and this causes an extended delay to the drop in brightness after the initial supernova peak, the characteristic of a type II-P supernova.

text: In nuclear physics, nuclear fusion is a reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles (neutrons and/or protons). The difference in mass between the products and reactants is manifested as the release of large amounts of energy. This difference in mass arises due to the difference in atomic "binding energy" between the atomic nuclei before and after the reaction. Fusion is the process that powers active or "main sequence" stars, or other high magnitude stars.

text: Michelin stars are a rating system used by the red Michelin guide to grade restaurants on their quality. The guide was originally developed in 1900 to show French drivers where local amenities such as restaurants and mechanics were, the rating system was first introduced in 1926 as a single star, with the second and third stars introduced in 1933. According to the Guide, one star signifies "a very good restaurant", two stars are "excellent cooking that is worth a detour", and three stars mean "exceptional cuisine that is worth a special journey". The listing of starred restaurants is updated once a year.

text: Supergiants can also be defined as a specific phase in the evolutionary history of certain stars. Stars with initial masses above  quickly and smoothly initiate core helium fusion after they have exhausted their hydrogen, continue fusing heavier elements after helium exhaustion until they develop an iron core, and then the core collapses to produce a supernova.  Once these massive stars leave the main sequence their atmospheres inflate and they are described as supergiants.  Stars initially under  will never form an iron core and in evolutionary terms do not become supergiants, although they can reach luminosities thousands of times the sun's. They cannot fuse carbon and heavier elements after their core helium is exhausted, so they eventually just lose their outer layers and become a white dwarf.  The phase where these stars have both hydrogen and helium burning shells is referred to as the asymptotic giant branch (AGB), as stars gradually become more and more luminous class M stars.  Stars of  may fuse sufficient carbon on the AGB to produce an oxygen-neon core and an electron-capture supernova, but astrophysicists categorise these as super-AGB stars rather than supergiants.

text: Some kind of supernovas are expected to happen if a white dwarf collides with its nearby partner and consumes the outer matter of this partner. The white dwarf and its nearby partner have very high orbital velocities at this time. The huge mass lost of the white dwarf during the supernova causes the nearby partner to leave at its previous huge orbital speed of several hundred kilometers per second as a hypervelocity star. The supernova remnant of the exploding white dwarf leaves because of its own high orbital speed as a new fast traveling neutron star. This seems to be the most likely origin of most HVSs and fast traveling neutron stars.

text: It has been estimated that there are around 20,000 massive O-type stars in the galaxy. The low-mass sdO and CSPNe O-type stars are probably more common, although less luminous and therefore harder to find. Despite their short lifetimes, they are thought to be normal stages in the evolution of common stars only a little more massive than the Sun.

text: One of the highlights of Gretzky's season was his appearance in the 1979 WHA All-Star Game. The format was a three-game series between the WHA All-Stars and Dynamo Moscow played at Edmonton's Northlands Coliseum. The WHA All-Stars were coached by Jacques Demers, who put Gretzky on a line with his boyhood idol Gordie Howe and Howe's son, Mark. In game one, the line scored seven points, and the WHA All-Stars won by a score of 4–2. In game two, Gretzky and Mark Howe each scored a goal and Gordie Howe picked up an assist as the WHA won 4–2. The line did not score in the final game, but the WHA won by a score of 4–3.

text: This star is considered a solar analog—meaning that it is photometrically analogous to the Sun. Like the Sun, it has a magnetic activity cycle. It shares a common proper motion through space with the spectroscopic binary star system HD 122742, and in the past the three may have formed a triple star system. In the Bright Star Catalogue, it was noted as having an infrared excess. This may have been accreted from the HD 122742 system when the three stars were closer to each other.

text: Nuclear fusion takes place inside the stars, and we can really see this light redshifted: this is the main source of the cosmic ultraviolet- and visual background.  However, a significant amount of this starlight is not observed directly. Dust in the host galaxies can absorb it and re-emit it in the infrared, contributing to the CIB. Although most of today's galaxies contain little dust (e.g. elliptical galaxies are practically dustless), there are some special stellar systems even in our vicinity which are extremely bright in the infrared and at the same time faint (often almost invisible) in the optical. These ultraluminous infrared galaxies (ULIRGs) are just in a very active star formation period: they are just in a collision or in a merge with another galaxy. In the optical this is hidden by the huge amount of dust, and the galaxy is bright in the infrared due to the same reason. Galaxy collisions and mergers were more frequent in the cosmic past: the global star formation rate of the Universe peaked around redshift z = 1...2, and was 10 to 50 times the average value today. These galaxies in the z = 1...2 redshift range give 50 to 70 percent of the full brightness of the CIB.

text: The next All-Star Game will take place in 2017 and will be held in Los Angeles. This will be the third time that an All-Star game is held in Los Angeles. The last two All-Star Games in Nashville, Tennessee and Columbus, Ohio were the first times that the respective cities had hosted the event. The format was changed so that it is no longer a singular all-star game per se; instead, four all-star teams, each representing one of the league's four divisions, will participate in a two-round knockout tournament, with each game being two 10-minute halves in length and played with three skaters on each team.

This method works best for young planets that emit infrared light and are far from the glare of the star.  Currently, this list includes both directly imaged planets and imaged planetary-mass companions (objects that orbit a star but formed through a binary-star-formation process, not a planet-formation process).

text: The nucleus of the Sombrero galaxy is classified as a low ionization nuclear emission region (LINER).  These are nuclear regions where ionized gas is present, but the ions are only weakly ionized (i.e. the atoms are missing relatively few electrons).  The source of energy for ionizing the gas in LINERs has been debated extensively.  Some LINER nuclei may be powered by hot, young stars found in star formation regions, whereas other LINER nuclei may be powered by active galactic nuclei (highly energetic regions that contain supermassive black holes).  Infrared spectroscopy observations have demonstrated that the nucleus of the Sombrero Galaxy is probably devoid of any significant star formation activity.  However, a supermassive black hole has been identified in the nucleus (as discussed in the subsection below), so this active galactic nucleus is probably the energy source that weakly ionizes the gas in the Sombrero Galaxy.

text: Two of Roberts' novels, Sanctuary and Magic Moments, had previously been made into TV movies. In 2007, Lifetime Television adapted four Nora Roberts novels into TV movies: Angels Fall starring Heather Locklear, Montana Sky starring Ashley Williams, Blue Smoke starring Alicia Witt, and Carolina Moon starring Claire Forlani. This was the first time that Lifetime had adapted multiple works by the same author. Four more films were released on four consecutive Saturdays in March and April 2009. The 2009 collection included Northern Lights starring LeAnn Rimes and Eddie Cibrian, Midnight Bayou starring Jerry O'Connell, High Noon starring Emilie de Ravin, and Tribute starring Brittany Murphy.

text: As far as axial precession is concerned, one scholar of Mithraism, David Ulansey, has interpreted Mithras as a personification of the force  responsible for precession (Ulansey, 1989). He argues that the cult was a religious response to Hipparchus's discovery of precession, which—from the ancient geocentric perspective—amounted to the discovery that the entire cosmos (i.e., the outermost celestial sphere of the fixed stars) was moving in a previously unknown way. His analysis is based on the so-called "tauroctony": the image of Mithras killing a bull that was located in the central place in every Mithraic temple. In the standard tauroctony, Mithras and the bull are accompanied by a dog, a snake, a raven, and a scorpion.  According to Ulansey, the tauroctony is a star chart. The bull is Taurus, a constellation of the zodiac. In the  astrological age that preceded the time of Hipparchus, the vernal equinox had taken place when the Sun was in the constellation of Taurus, and during that previous epoch the constellations of Canis Minor (The Dog), Hydra (The Snake), Corvus (The Raven), and Scorpius (The Scorpion)—i.e., the constellations that correspond to the animals depicted in the tauroctony—all lay on the celestial equator (the location of which is shifted by the precession) and thus had privileged positions in the sky during that epoch. Mithras himself represents the constellation Perseus, which is located directly above Taurus the Bull: the same location occupied by Mithras in the tauroctony image. Mithras' killing of the Bull, by this reasoning, represented the power possessed by this new god to shift the entire cosmic structure, turning the cosmic sphere so that the location of the spring equinox left the constellation of Taurus (a transition symbolized by the killing of the Bull), and the Dog, Snake, Raven, and Scorpion likewise lost their privileged positions on the celestial equator.

Since the volume of fuzzballs is a function of the Schwarzschild radius (2,954 meters per ), fuzzballs have a variable density that decreases as the inverse square of their mass (twice the mass is twice the diameter, which is eight times the volume, resulting in one‑quarter the density). A typical  fuzzball would have a mean density of . A bit of such a fuzzball the size of a drop of water would have a mass of twenty million metric tons, which is the mass of a granite ball 240 meters in diameter.  Though such densities are almost unimaginably extreme, they are, mathematically speaking, infinitely far from infinite density. Although the densities of typical stellar-mass fuzzballs are quite great—about the same as neutron stars<ref>Neutron stars have a mean density thought to be in the range of  which is equal to median-size fuzzballs ranging from 7.1 to 5.6 . However, the smallest fuzzballs are denser than neutron stars; a small,  fuzzball would be four to seven times denser than a neutron star.
On a “teaspoon” (≈4.929 mL) basis, which is a common measure for conveying density in the popular press to a general-interest readership, comparative mean densities are as follows:

text: Published after the death of Johannes, and with support from King Sobieski, the Prodromus Astronomiae consisted of three separate parts: a preface (labeled Prodromus), a star catalog (named Catalogus Stellarum), and an atlas of constellations (named Firmamentum Sobiescianum, sive Uranographia).Prodromus outlines the methodology and technology used in creating the star catalogue. It provides examples of the use of the sextant and quadrant by Johannes, in tandem with known positions of the sun, in calculating each stars' longitude and latitude. The written draft of the Catalogus Stellarum consists of 183 leaves, 145, alphabetized according to constellation, containing star positions. Each star had specific information recorded in columns: the reference number and magnitude found by astronomer Tycho Brahe, Johannes' own magnitude calculation, the star's longitude and latitude by both ecliptic coordinates measured by angular distances and meridian altitudes found using Johannes' quadrant, and the star's equatorial coordinates calculated using spherical trigonometry. The printed version was similar to the written draft, except the two columns describing a star's ecliptic coordinates were combined, and only the single best value for the star's latitude and longitude was given. Also, the printed version held more than 600 new stars and 12 new constellations not documented in the written draft, bringing its total to 1564. Although the observations of the catalog used nothing more than the astronomer's naked eye, the measurements were so precise as to be used in the making of celestial globes into the early 18th Century.Firmamentum Sobiescianum, while technically part of the Prodromus Astronomiae as a well, was likely published separately and in tighter circulation. Housing its own cover page and page-numbering system, the atlas consisted of two hemispheres and 54 double-page plates of 73 constellations. Both the northern and southern hemispheres were centered on an ecliptic pole, and most star locations were all based off Johannes' own observations. Those that were not, the southern polar stars, were based on a catalog and map published in 1679 by Edmond Halley.

text: Hindu astrology is primarily based on constellations or nakshatras, the longitudes of constellations differ from place to place but for purposes of predictive astrology each constellation is treated as having a jurisdiction of thirteen degrees twenty minutes i.e. the zodiac divided by twenty-seven nakshatras or 360 degrees divided by 27; the word, sidereal, pertains to the zodiac of the constellations of the fixed stars. All signs are as in the fixed zodiac and the longitudes of planets also refer to their location on the fixed zodiac. According to older Hindu texts, the words signs and houses fall on each other, but the count of the signs is always made from Aries which is the first sign, and the count of the house begins from the lagna; the duration of a sign rising differs from latitude to latitude.

text: Three of constellation's stars are visible to the naked eye: Alpha Comae Berenices, Beta Comae Berenices and Gamma Comae Berenices. They form a 45-degree triangle, from which Berenice's imaginary tresses hang. The constellation's brightest star is Beta Comae Berenices, a 4.26-magnitude main sequence star similar to the Sun. Coma Berenices contains the North Galactic Pole and one of the richest known galaxy clusters, the Coma Cluster, part of the Coma Supercluster. Galaxy Malin 1, in the constellation, is the first known giant low-surface-brightness galaxy. Supernova SN 2005ap discovered in Coma Berenices is the brightest known, and SN 1940B was the first observed example of a type II supernova. The star FK Comae Berenices is the prototype of an eponymous class of variable stars. The constellation is the radiant of one meteor shower, Coma Berenicids, which has one of the fastest meteor speeds: up to 65 km/s (40 mps).

text: A k-type main-sequence star (K V), also referred to as an orange dwarf orK dwarf, is a main-sequence (hydrogen-burning) star of spectral type K and luminosity class V. These stars are intermediate in size between red M-type main-sequence stars and yellow G-type main-sequence stars. They have masses between 0.45 and 0.8 times the mass of the Sun and surface temperatures between 3,900 and 5,200 K.Better-known examples include Alpha Centauri B (K1 V) and Epsilon Indi. These stars are of particular interest in the search for extraterrestrial life because they are stable on the main sequence for a very long time (15 to 30 billion years, compared to 10 billion for the Sun). This may create an opportunity for life to evolve on terrestrial planets orbiting such stars. K-type stars also emit less ultraviolet radiation (which can damage DNA and thus hamper the emergence of life) than G-type stars like the Sun. K-type main-sequence stars are about three to four times as abundant as G-type main-sequence stars, making planet searches easier.

text: In stars that undergo nuclear fusion, fuel consists of atomic nuclei that can release energy by the absorption of a proton or neutron. In most stars the fuel is provided by hydrogen, which can combine to form helium through the proton-proton chain reaction or by the CNO cycle. When the hydrogen fuel is exhausted, nuclear fusion can continue with progressively heavier elements, although the net energy released is lower because of the smaller difference in nuclear binding energy. Once iron-56 or nickel-56 nuclei are produced, no further energy can be obtained by nuclear fusion as these have the highest nuclear binding energies. The elements then on use up energy instead of giving off energy when fused. Therefore, fusion stops and the star dies. In attempts by humans, fusion is only carried out with hydrogen (isotope of 2 and 3) to form helium-4 as this reaction gives out the most net energy. Electric confinement (ITER), inertial confinement(heating by laser) and heating by strong electric currents are the popular methods used. .

text: RHIC is an intersecting storage ring particle accelerator. Two independent rings (arbitrarily denoted as "Blue" and "Yellow" rings) circulate heavy ions and/or protons in opposite directions and allow a virtually free choice of colliding positively charged particles (the eRHIC upgrade will allow collisions between positively and negatively charged particles). The RHIC double storage ring is itself hexagonally shaped and  long in circumference, with curved edges in which stored particles are deflected and focused by 1,740 superconducting  magnets using niobium-titanium conductors. The dipole magnets operate at . The six interaction points (between the particles circulating in the two rings) are at the middle of the six relatively straight sections, where the two rings cross, allowing the particles to collide. The interaction points are enumerated by clock positions, with the injection near 6 o'clock. Two large experiments, STAR and PHENIX, are located at 6 and 8 o'clock respectively.

text: A microtron is a type of particle accelerator concept originating from the cyclotron in which the accelerating field is not applied through large D-shaped electrodes, but through a linear accelerator structure. The classic microtron was invented by Vladimir Veksler. The kinetic energy of the particles is increased by a constant amount per field change (one half or a whole revolution). Microtrons are designed to operate at constant field frequency and magnetic field in the ultrarelativistic limit. Thus they are especially suited for very light elementary particles, namely electrons.

text: A supernova is a massive explosion of a star that occurs under two principal scenarios. The first is that a white dwarf star undergoes a nuclear-based explosion after it reaches its Chandrasekhar limit after absorbing mass from a neighboring star (usually a red giant).  The second, and more common, cause is when a massive star, usually a supergiant, reaches nickel-56 in its nuclear fusion (or burning) processes. This isotope undergoes radioactive decay into iron-56, which has one of the highest binding energies of all of the isotopes, and is the last element that produces a net release of energy by nuclear fusion, exothermically.

text: With modern insights into quantum mechanics and technology that can accelerate particles close to the speed of light, particle physics has devised a Standard Model to describe forces between particles smaller than atoms. The Standard Model predicts that exchanged particles called gauge bosons are the fundamental means by which forces are emitted and absorbed. Only four main interactions are known: in order of decreasing strength, they are: strong, electromagnetic, weak, and gravitational. High-energy particle physics observations made during the 1970s and 1980s confirmed that the weak and electromagnetic forces are expressions of a more fundamental electroweak interaction.

text: When a cluster of stars is formed at about the same time, the life span of these stars will depend on their individual masses. The most massive stars will leave the main sequence first, followed steadily in sequence by stars of ever lower masses. Thus the stars will evolve in order of their position on the main sequence, proceeding from the most massive at the left toward the right of the HR diagram. The current position where stars in this cluster are leaving the main sequence is known as the turn-off point. By knowing the main sequence lifespan of stars at this point, it becomes possible to estimate the age of the cluster.

text: It was already known in the 1920s that a plasma has a limited capacity for current maintenance, Irving Langmuir characterized double layers in the laboratory and called these structures double-sheaths.  In the 1950s a thorough  study of double layers  started in the laboratory (e.g. Schönhuber, 1958). Many groups are still working on this topic theoretically, experimentally and numerically. It was first proposed by Hannes Alfvén (the developer of magnetohydrodynamics from laboratory experiments) that the polar lights or Aurora Borealis are created by electrons accelerated in the magnetosphere of the Earth. He supposed that the electrons were accelerated electrostatically by an electric field localized in a small volume  bounded by two charged regions, and the so-called double layer would accelerate electrons earthwards.   Since then other mechanisms which involve wave-particle interactions have been proposed as being feasible, from extensive spatial and temporal in situ studies of auroral particle characteristics.

text: Until just a few decades ago, hot supergiants were not considered likely to explode, but observations have shown otherwise.  Blue supergiants form an unexpectedly high proportion of confirmed supernova progenitors, partly due to their high luminosity and easy detection, while not a single Wolf-Rayet progenitor has yet been clearly identified.  Models have had difficulty showing how blue supergiants lose enough mass to reach supernova without progressing to a different evolutionary stage.  One study has shown a possible route for low-luminosity post-red supergiant luminous blue variables to collapse, most likely as a type IIn supernova.

text: The first cyclotron, an early type of particle accelerator, was built by Ernest O. Lawrence in 1931, with a radius of just a few centimetres and a particle energy of 1 megaelectronvolt (MeV). Since then, accelerators have grown enormously in the quest to produce new particles of greater and greater mass. As accelerators have grown, so too has the list of known particles that they might be used to investigate.

text: In various countries, particularly the United States, these may be referred to as "star ranks" for the number of stars worn on some rank insignia: typically one-star for brigadier general or equivalent with the addition of a star for each subsequent rank. In the United States, five stars has been the highest rank regularly attainable (excluding the Marines and Coast Guard, which have traditionally served as branches of the Navy in times of war and thus under the command of a Fleet Admiral).  There also exists the specialty ranks of General of the Armies of the United States and Admiral of the Navy which at their inception were considered senior four star officers but came to be considered six-star rank after the creation of five star officers. To date only one other officer has held a six star rank in their lifetime, John J. Pershing while George Washington was posthumously promoted to the post in 1976. Additionally, Admiral George Dewey was promoted to Admiral of the Navy but died well before statute made it senior to an Admiral of the Fleet upon the latter's inception.

text: The formation of globular clusters remains a poorly understood phenomenon and it remains uncertain whether the stars in a globular cluster form in a single generation or are spawned across multiple generations over a period of several hundred million years. In many globular clusters, most of the stars are at approximately the same stage in stellar evolution, suggesting that they formed at about the same time. However, the star formation history varies from cluster to cluster, with some clusters showing distinct populations of stars. An example of this is the globular clusters in the Large Magellanic Cloud (LMC) that exhibit a bimodal population. During their youth, these LMC clusters may have encountered giant molecular clouds that triggered a second round of star formation. This star-forming period is relatively brief, compared to the age of many globular clusters.It has also been proposed that the reason for this multiplicity in stellar populations could have a dynamical origin. In the Antennae galaxy, for example, the Hubble Space Telescope has observed clusters of clusters, regions in the galaxy that span hundreds of parsecs, where many of the clusters will eventually collide and merge. Many of them present a significant range in ages, hence possibly metallicities, and their merger could plausibly lead to clusters with a bimodal or even multiple distribution of populations.

text: NGC 4631 contains a central starburst, which is a region of intense star formation.  The strong star formation is evident in the emission from ionized hydrogen and interstellar dust heated by the stars formed in the starburst.  The most massive stars that form in star formation regions only burn hydrogen gas through fusion for a short period of time, after which they explode as supernovae.  So many supernovae have exploded in the center of NGC 4631 that they are blowing gas out of the plane of the galaxy.  This superwind can be seen in X-rays and in spectral line emission.  The gas from this superwind has produced a giant, diffuse corona of hot, X-ray emitting gas around the whole galaxy.

text: This list contains all known stars and brown dwarfs at a distance of up to 5 parsecs (16.3 light-years) from the Solar System. In addition to the Solar System, there are another 56 stellar systems currently known lying within this distance. These systems contain a total of 60 hydrogen-fusing stars (of which 50 are red dwarfs), 13 brown dwarfs, and 4 white dwarfs. Despite the relative proximity of these objects to Earth, only nine of them have an apparent magnitude less than 6.5, which means only about 12% of these objects can be observed with the naked eye. Besides the Sun, only three are first-magnitude stars: Alpha Centauri, Sirius, and Procyon. All of these objects are located in the Local Bubble, a region within the Orion–Cygnus Arm of the Milky Way.

text: Some of the more prominent double stars include Gamma Coronae Australis—a pair of yellowish white stars 58 light years away from Earth, which orbit each other every 122 years. Widening since 1990, the two stars can be seen as separate with a 100 mm aperture telescope; they are separated by 1.3 arcseconds at an angle of 61 degrees. They have a combined visual magnitude of 4.2; each component is an F8V dwarf star with a magnitude of 5.01. Epsilon Coronae Australis is an eclipsing binary belonging to a class of stars known as W Ursae Majoris variables. These star systems are known as contact binaries as the component stars are so close together they touch. Varying by a quarter of a magnitude around an average apparent magnitude of 4.83 every seven hours, the star system lies 98 light years away. Its spectral type is F4VFe-0.8+. At the southern end of the crown asterism are the stars Eta¹ and Eta² Coronae Australis, which form an optical double. Of magnitude 5.1 and 5.5, they are separable with the naked eye and are both white. Kappa Coronae Australis is an easily resolved optical double—the components are of apparent magnitudes 6.3 and 5.7 and are 1700 and 490 light years away respectively. They appear at an angle of 359 degrees, separated by 21.6 arcseconds. Kappa² is actually the brighter of the pair and is more bluish white, with a spectral type of B9V, while Kappa¹ is of spectral type A0III. Lying 202 light years away, Lambda Coronae Australis is a double splittable in small telescopes. The primary is a white star of spectral type A2Vn and magnitude of 5.1, while the companion star has a magnitude of 9.7. The two components are separated by 29.2 arcseconds at an angle of 214 degrees.

text: The open cluster NGC 4755, better known as the Jewel Box or  Crucis Cluster, has an overall magnitude of 4.2—to the naked eye it appears to be a fuzzy star—and is about 7600 light-years from Earth. The cluster was given its name by John Herschel. About seven million years old, an age that makes it one of the youngest open clusters in the Milky Way, it appears to have the shape of a letter A. The Jewel Box Clusters is a Shapley class g and Trumpler class I 3 r cluster; it is a very rich, centrally-concentrated cluster detached from the surrounding star field. It has more than 100 stars that range significantly in brightness. The brightest stars are mostly blue supergiants, though the cluster contains a few bright red supergiants. Kappa Crucis is a true member of the cluster that bears its name, and is one of the brighter stars at magnitude 5.9.

text: Beta Lyrae is a semidetached binary system made up of a stellar class B7 main sequence primary star and a secondary that is probably also a B-type star. The fainter, less massive star in the system was once the more massive member of the pair, which caused it to evolve away from the  main sequence first and become a giant star. Because the pair are in a close orbit, as this star expanded into a giant it filled its Roche lobe and transferred most of its mass over to its companion. The secondary, now more massive star is surrounded by an accretion disk from this mass transfer, with bipolar, jet-like features projecting perpendicular to the disk. This accretion disk blocks humans' view of the secondary star, lowering its apparent luminosity and making it difficult for astronomers to pinpoint what its stellar type is. The amount of mass being transferred between the two stars is about solar masses per year, or the equivalent of the Sun's mass every 50,000 years, which results in an increase in orbital period of about 19 seconds each year.  The spectrum of Beta Lyrae shows emission lines produced by the accretion disc.  The disc produces around 20% of the brightness of the system.

text: There were also significant implications into star formation.  COBE observations provide important constraints on the cosmic star formation rate, and help us calculate the EBL spectrum for various star formation histories.  Observation made by COBE require that star formation rate at redshifts of z ≈ 1.5 to be larger than that inferred from UV-optical observations by a factor of 2.  This excess stellar energy must be mainly generated by massive stars in yet-undetected dust enshrouded galaxies or extremely dusty star forming regions in observed galaxies.  The exact star formation history cannot unambiguously be resolved by COBE and further observations must be made in the future.

text: Mu Cephei is nearing death. It has begun to fuse helium into carbon, whereas a main sequence star fuses hydrogen into helium.  When a supergiant star has converted elements in its core to iron, the core collapses to produce a supernova and the star is destroyed, leaving behind a vast gaseous cloud and a small, dense remnant.  For a star as massive as Mu Cephei the remnant is likely to be a black hole.  The most massive red supergiants will evolve back to blue supergiants, Luminous blue variables, or Wolf-Rayet stars before their cores collapse, and Mu Cephei appears to be massive enough for this to happen.  A post-red supergiant will produce a type IIn or type II-b supernova, while a Wolf Rayet star will produce a type Ib or Ic supernova.

text: The mass/luminosity relation is important because it can be used to find the distance to binary systems which are too far for normal parallax measurements, using a technique called "dynamical parallax". In this technique, the masses of the two stars in a binary system are estimated, usually as being the mass of the Sun. Then, using Kepler's laws of celestial mechanics, the distance between the stars is calculated. Once this distance is found, the distance away can be found via the arc subtended in the sky, giving a preliminary distance measurement. From this measurement and the apparent magnitudes of both stars, the luminosities can be found, and by using the mass–luminosity relationship, the masses of each star. These masses are used to re-calculate the separation distance, and the process is repeated. The process is iterated many times, and accuracies as high as 5% can be achieved. The mass/luminosity relationship can also be used to determine the lifetime of stars by noting that lifetime is approximately proportional to M/L. One finds that more massive stars live shorter. A more sophisticated calculation factors in a star's loss of mass over time.

text: The true nature of these objects (or even whether the current classification scheme is accurate) remains unknown, although the leading hypothesis is that they originate from the mergers of binary neutron stars or a neutron star with a black hole. Such mergers might also be expected to produce kilonovae, and evidence for a kilonova associated with GRB 130603B has been seen. The mean duration of these events of 0.2 seconds suggests a source of very small physical diameter in stellar terms; less than 0.2 light-seconds (about 60,000 km or 37,000 miles—four times the Earth's diameter). This further suggests a very compact object as the source. The observation of minutes to hours of X-ray flashes after a short gamma-ray burst is consistent with small particles of a primary object like a neutron star initially swallowed by a black hole in less than two seconds, followed by some hours of lesser energy events, as remaining fragments of tidally disrupted neutron star material (no longer neutronium) remain in orbit to spiral into the black hole, over a longer period of time. A small fraction of short gamma-ray bursts are probably produced by giant flares from soft gamma repeaters in nearby galaxies.

text: In February 2007, GRB 070201, a short gamma-ray burst arrived at Earth from the direction of the Andromeda Galaxy.  The prevailing explanation of most short gamma-ray bursts is the merger of a neutron star with either a neutron star or a black hole. LIGO reported a non-detection for GRB 070201, ruling out a merger at the distance of Andromeda with high confidence. Such a constraint was predicated on LIGO eventually demonstrating a direct detection of gravitational waves.

The tertiary is not visible in telescopes. AA Ceti is an eclipsing variable star; the tertiary star passes in front of the primary and causes the system's apparent magnitude to decrease by 0.5 magnitudes. UV Ceti is an unusual binary variable star. 8.7 light-years from Earth, the system consists of two red dwarfs. both of magnitude 13. One of the stars is a flare star, which are prone to sudden, random outbursts that last several minutes; these increase the pair's apparent brightness significantly - as high as magnitude 7.

text: All stars more massive than about  are expected to end their lives when their core collapses, typically producing a supernova explosion.  Up to about , a type II-P supernova is always produced from the red supergiant stage.  More massive stars can lose mass quickly enough that they evolve towards higher temperatures before their cores can collapse, particularly for rotating stars and models with especially high mass loss rates.  These stars can produce type II-L or type IIb supernovae from yellow or blue supergiants, or type Ib/c supernovae from Wolf-Rayet stars.  Models of rotating  stars predict a peculiar type II supernova similar to SN 1987A from a blue supergiant progenitor.  On the other hand, non-rotating  models predict a type II-P supernova from a red supergiant progenitor.

text: Of the red stars observed by Hertzsprung, the dwarf stars also followed the spectra-luminosity relationship discovered by Russell. However, the giant stars are much brighter than dwarfs and so, do not follow the same relationship. Russell proposed that the "giant stars must have low density or great surface-brightness, and the reverse is true of dwarf stars". The same curve also showed that there were very few faint white stars.

text: The common use of "dwarf" to mean main sequence is confusing in another way, because there are dwarf stars which are not main-sequence stars. For example, a white dwarf is the dead core of a star that is left after the star has shed its outer layers, that is much smaller than a main-sequence star, roughly the size of Earth. These represent the final evolutionary stage of many main-sequence stars.

text: The system consists of four T Tauri stars that are located within the TW Hydrae association.  Within the system, there are two separate systems of binary stars.  Each system (separately catalogued as "HD 98800 A" and "HD 98800B") consists of two stars.  Although the four stars are gravitationally bound, the distance separating the two binary pairs is about 50 astronomical units (somewhat more than the average distance between the Sun and Pluto).  Not much is known about each individual star, except that they are basically Solar twin stars.

text: Quantum tunnelling is essential for nuclear fusion in stars. Temperature and pressure in the core of stars are insufficient for nuclei to overcome the Coulomb barrier in order to achieve a thermonuclear fusion. However, there is some probability to penetrate the barrier due to quantum tunnelling. Though the probability is very low, the extreme number of nuclei in a star generates a steady fusion reaction over millions or even billions of years - a precondition for the evolution of life in insolation habitable zones.

text: Two of the franchises Demers coached in the WHA were the Chicago Cougars and the Quebec Nordiques. Additionally, he was the exceedingly popular coach of the Indianapolis Racers, which won the Eastern Division championship under his guidance. Demers had the opportunity to coach Wayne Gretzky in the 1979 WHA All-Star Series. The format of the series was a three-game set that pitted the WHA All-Stars against HC Moscow Dynamo. Demers asked Gordie Howe if it was okay to put him on a line with Wayne Gretzky and his son Mark Howe. In Game One, the line scored seven points as the WHA All-Stars won by a score of 4–2. In Game Two, Gretzky and Mark Howe each scored a goal and Gordie Howe picked up an assist as the WHA won 4–2. The line did not score in the final game, but the WHA won by a score of 4–3.

text: In Chinese astronomy, the stars corresponding to Canis Minor lie in the The Vermilion Bird of the South (南方朱雀, Nán Fāng Zhū Què). Procyon, Gomeisa and Eta Canis Minoris form an asterism known as Nánhé, the Southern River. With its counterpart, the Northern River Beihe (Castor and Pollux), Nánhé was also associated with a gate or sentry. Along with Zeta and 8 Cancri, 6 Canis Minoris and 11 Canis Minoris formed the asterism Shuiwei, which literally means "water level". Combined with additional stars in Gemini, Shuiwei represented an official who managed floodwaters or a marker of the water level. Neighboring Korea recognized four stars in Canis Minor as part of a different constellation, "the position of the water". This constellation was located in the Red Bird, the southern portion of the sky.

text: The stars of Auriga were incorporated into several Chinese constellations. Wuche, the five chariots of the celestial emperors and the representation of the grain harvest, was a constellation formed by Alpha Aurigae, Beta Aurigae, Beta Tauri, Theta Aurigae, and Iota Aurigae. Sanzhu or Zhu was one of three constellations which represented poles for horses to be tethered. They were formed by the triplets of Epsilon, Zeta, and Eta Aurigae; Nu, Tau, and Upsilon Aurigae; and Chi and 26 Aurigae, with one other undetermined star. Xianchi, the pond where the sun set and Tianhuang, a pond, bridge, or pier, were other constellations in Auriga, though the stars that composed them are undetermined. Zuoqi, representing chairs for the emperor and other officials, was made up of nine stars in the east of the constellation. Bagu, a constellation mostly formed from stars in Camelopardalis representing different types of crops, included the northern stars of Delta and Xi Aurigae.

text: In main sequence stars of less than about 10 solar masses, the outer envelope of the star contains a region where partial ionization of hydrogen and helium raises the heat capacity.  The relatively low temperature in this region simultaneously causes the opacity due to heavier elements to be high enough to produce a steep temperature gradient. This combination of circumstances produces an outer convection zone, the top of which is visible in the Sun as solar granulation. Low mass main sequences of stars, such as red dwarfs below 0.35 solar masses, as well as pre-main sequence stars on the Hayashi track, are convective throughout and do not contain a radiation zone.

text: Tucana is a constellation of stars in the southern sky, named after the toucan, a South American bird. It is one of twelve constellations conceived in the late sixteenth century by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman. Tucana first appeared on a  celestial globe published in 1598 in Amsterdam by Plancius and Jodocus Hondius and was depicted in Johann Bayer's star atlas Uranometria of 1603. French explorer and astronomer Nicolas Louis de Lacaille gave its stars Bayer designations in 1756. The constellations Tucana, Grus, Phoenix and Pavo are collectively known as the "Southern Birds".

text: RR Caeli is a double star in the constellation Caelum. It is approximately 66 light years from Earth. It was first noted to be a high-proper motion star in 1955 by Jacob Luyten, and given the name LFT 349. Discovered to be an eclipsing binary in 1979, it has a baseline magnitude of 14.36, dimming markedly every 7.2 hours for an interval of around 10 minutes, due to the total eclipse of the brighter star by the fainter one. Its variability in brightness led to its being given the variable star designation RR Caeli in 1984. This star system consists of a red dwarf of spectral type M6 and a white dwarf that orbit each other every seven hours; the former is 18% as massive as the Sun, while the latter has 44% of the Sun's mass. The red dwarf is tidally locked with the white dwarf, meaning it displays the same side to the heavier star. The system is also a post-common-envelope binary, and the red dwarf star is transferring material onto the white dwarf. In approximately 9–20 billion years, RR Caeli will likely become a cataclysmic variable star due to the period's gradual shortening, leading to increasing rates of transfer of hydrogen to the surface of the white dwarf.

text: On the surface of the white dwarf, the accreted gas will become compressed and heated. At some point the accumulated gas can reach the conditions necessary for hydrogen fusion to occur, producing a runaway reaction that will drive a portion of the gas from the surface. This would result in a (recurrent) nova explosion—a cataclysmic variable star—and the luminosity of the white dwarf rapidly would increase by several magnitudes for a period of several days or months. An example of such a star system is RS Ophiuchi, a binary system consisting of a red giant and a white dwarf companion. RS Ophiuchi has flared into a (recurrent) nova on at least six occasions, each time accreting the critical mass of hydrogen needed to produce a runaway explosion.

text: The discovery of this massive star also cast some doubt on the prevailing theory that the ULX is generated by a black hole accretion disc. A calculation of the orbits of a binary system with the components detailed above suggests an orbital period of 200–300 hours, depending on the exact masses involved. However, a 2006 study found no evidence of any periodic variations at all in the luminosity of the X-ray source, although the strength does vary randomly over timescales of a few days. As a result, the study advanced an alternative theory that the X-ray source is generated by the supergiant's corona, which would be capable of generating a very powerful X-ray source because of the extreme luminousity of the parent star. Supergiant stars also known to experience large variations in luminosity more or less at random, which would heat the corona to varying degrees and explain the observed changes in X-ray emission strength.

text: Most stars are currently classified under the Morgan–Keenan (MK) system using the letters O, B, A, F, G, K, and M, a sequence from the hottest (O type) to the coolest (M type). Each letter class is then subdivided using a numeric digit with 0 being hottest and 9 being coolest (e.g. A8, A9, F0, F1 form a sequence from hotter to cooler). The sequence has been expanded with classes for other stars and star-like objects that do not fit in the classical system, such as class D for white dwarfs and class C for carbon stars.

text: A-type stars are among the more common naked eye stars, and are white or bluish-white. They have strong hydrogen lines, at a maximum by A0, and also lines of ionized metals (Fe II, Mg II, Si II) at a maximum at A5. The presence of Ca II lines is notably strengthening by this point. About 1 in 160 (0.625%) of the main-sequence stars in the solar neighborhood are A-type stars.

text: Greenhouse Item was an American nuclear test conducted on May 25, 1951, as part of Operation Greenhouse at the Pacific Proving Ground, specifically on the island of Engebi in the Eniwetok Atoll in the Central Pacific Ocean. This test explosion was the first test of a boosted fission weapon. In this test deuterium-tritium (D-T) gas was injected into the enriched uranium core of a nuclear fission bomb. The extreme heat of the fissioning bomb produced thermonuclear fusion reactions within the D-T gas, but not enough of them to be considered a full nuclear fusion bomb. This fusion reaction released a large number of free neutrons, which greatly increased the efficiency of the nuclear fission reaction. The explosive yield of this bomb was 45.5 kilotons, about twice the yield of the unboosted bomb.

text: The first extrasolar X-ray source was discovered on June 12, 1962. This source is called Scorpius X-1, the first X-ray source found in the constellation of Scorpius, located in the direction of the center of the Milky Way. Scorpius X-1 is some 9,000 ly from Earth and after the Sun is the strongest X-ray source in the sky at energies below 20 keV. Its X-ray output is 2.3 × 10 W, about 60,000 times the total luminosity of the Sun. Scorpius X-1 itself is a neutron star. This system is classified as a low-mass X-ray binary (LMXB); the neutron star is roughly 1.4 solar masses, while the donor star is only 0.42 solar masses.

text: Gould designations for stars are similar to Flamsteed designations in the way that they number stars within a constellation in increasing order of right ascension. Each star is assigned an integer (starting at 1), followed by " G. " (or occasionally followed directly by a "G" without a space), and then the Latin genitive of the constellation it lies in. See 88 modern constellations for a list of constellations and the genitive forms of their names.

text: The constellations around the South Pole were not observable from north of the equator, by Babylonians, Greeks, Chinese or Arabs. The modern constellations in this region were defined during the Age of Exploration, notably by Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman at the end of sixteenth century. These twelve Dutch-created southern constellations represented flora and fauna of the East Indies and Madagascar. They were depicted by Johann Bayer in his star atlas Uranometria of 1603. Several more were created by Nicolas Louis de Lacaille in his star catalogue, published in 1756. By the end of the Ming Dynasty, Xu Guangqi introduced 23 asterisms of the southern sky based on the knowledge of western star charts. These asterisms have since been incorporated into the traditional Chinese star maps. Among the IAU's 88 modern constellations, there are 15 Dutch-created constellations (including Apus, Camelopardalis, Chamaeleon, Columba, Dorado, Grus, Hydrus, Indus, Monoceros, Musca, Pavo, Phoenix, Triangulum Australe, Tucana and Volans).

text: The concept of an all-star game was not revived until June 1950, when the newly christened "Pro Bowl" was approved. The game was sponsored by the Los Angeles Publishers Association. It was decided that the game would feature all-star teams from each of the league's two conferences rather than the league champion versus all-star format which had been used previously. This was done to avoid confusion with the Chicago College All-Star Game, an annual game which featured the league champion against a collegiate all-star team. The teams would be led by the coach of each of the conference champions. Immediately prior to the Pro Bowl, following the 1949 season, the All-America Football Conference, which contributed three teams to the NFL in a partial merger in 1950, held its own all-star game, the Shamrock Bowl.

text: The Nova Bomb is a weapon with the power to destroy a solar system. It utilizes a powerful fictional element called Voltarium. It is then fired into the core of a star where it reverses the gravity in an area larger than that of the star. The internal pressure of the star then creates a nova, destroying everything in the star's vicinity. On a smaller scale, it can destroy a planet, like the planet Samsarra in the episode "Point of the Spear". In episode 2 of season 1 all of the ship's 40 nova bombs are fired into a black hole, unleashing an explosive power equaling 2 million Teratons of TNT and turning the black hole into a white hole or "a miniature version of the Big Bang".

text: Charmed baryons are formed in high-energy particle collisions, such as those produced by particle accelerators. The general method to find them is to detect their decay products, identify what particles they are, and measure their momenta. If all the decay products are found and measured correctly, then the mass of the parent particle may be calculated. As an example, a favored decay of the  is into a proton, a kaon and a pion. The momenta of these (rather stable) particles are measured by the detector and using the usual rules of four-momentum using the correct relativistic equations, this gives a measure of the mass of the parent particle.

text: On April 1, 2015, it was revealed that Will Ferrell, Kristen Wiig, and Jessica Lowndes were set to star in the film as a parody of the genre of Lifetime films, with Rachel Lee Goldenberg directing and Andrew Steele writing the screenplay. Adam McKay's production company Gary Sanchez Productions and Ferrell are executive producing. The next day, Ferrell issued a statement regarding the film saying "We are deeply disappointed that our planned top-secret project was made public, Kristen and I have decided it is in the best interest for everyone to forgo the project entirely, and we thank Lifetime and all the people who were ready to help us make this film." shooting down the prospect of the film being released. However, in June 2015, a billboard for the film was spotted with a release date of June 20, 2015.

text: In the traditional Arabic astrological system, the moon was seen to move through 28 distinct manazil (singular: manzil = house) during the normal solar year, each manzil lasting, therefore, for about 13 days. One or more manazil were then grouped into a nawaa (pluaral anwaa) which were tied to a given weather pattern. In other words, the yearly pattern was divided in the following manner: A year was divided into anwaa, each of which was made up of one more manazil, which were associated with a dominant star or constellation. These stars and constellations were sometimes, but not always, connected in some way to constellations in the Zodiac. Moreover, as the anwaa' repeat on a regular, solar cycle, they can be correlated to fixed points on the Gregorian calendar.

text: Further types of variable stars, such as RV Tauri variables and PV Telescopii variables, are often described as supergiants.  RV Tau stars are frequently assigned spectral types with a supergiant luminosity class on account of their low surface gravity, and they are amongst the most luminous of the AGB and post-AGB stars, having masses similar to the sun. Likewise the even rarer PV Tel variables are often classified as supergiants, but have lower luminosities than supergiants and peculiar B[e] spectra extremely deficient in hydrogen.  Possibly they are also post-AGB objects, or perhaps "born-again" AGB stars.

text: There are two major differences between the synchrocyclotron and the classical cyclotron. In the synchrocyclotron, only one dee retains its classical shape, while the other pole is open (see patent sketch). Furthermore, the frequency of oscillating electric field in a synchrocyclotron is decreasing continuously instead of kept constant so as to maintain cyclotron resonance for relativistic velocities. One terminal of the oscillating electric potential varying periodically is applied to the dee and the other terminal is on ground potential. The protons or deuterons to be accelerated are made to move in circles of increasing radius. The acceleration of particles takes place as they enter or leave the dee. At the outer edge, the ion beam can be removed with the aid of electrostatic deflector. It was possible to produce 200 MeV deuterons and 400 MeV α-particles with the first synchrocyclotron.

text: This is a chemically peculiar star and was first classified as a silicon star by American astronomer William Morgan in 1933. The stellar spectrum displays an overabundance of heavier elements; particularly silicon and gallium. These abundances may be caused by the magnetic field of the star, which produces concentrations of the observed elements in the outer atmosphere. It is a α² Canum Venaticorum-type variable star, ranging in magnitude from 5.15 down to 5.22. These variations are likely due to large spots or rings on the side of the star being observed.

text: The German cartographer Johann Bayer used the Greek letters Alpha through Eta to label the most prominent stars in the constellation. John Flamsteed gave nine stars Flamsteed designations, while one star he designated in the neighbouring constellation Crater—31 Crateris—ended up in Corvus.  Within the constellation's borders, there are 29 stars brighter than or equal to apparent magnitude 6.5.

text: The NGC 4038 Group is a group of galaxies across Corvus and Crater. The group may contain between 13 and 27 galaxies. The best-known member is the Antennae peculiar galaxy, located 0.25 north of 31 Crateris.  It consists of two interacting galaxies—NGC 4038 and 4039—that appear to have a heart shape as seen from Earth. The name originates from the huge tidal tails that come off the ends of the two galaxies, formed because of the spiral galaxies' original rotation. Both original galaxies were spiral galaxies and are now experiencing extensive star formation due to the interaction of gas clouds. The galaxies are 45 million light-years from Earth and each has multiple ultraluminous X-ray sources, the source of which is unknown. Astronomers theorize that they may be a rare type of x-ray emitting binary stars or intermediate-mass black holes. The Antennae galaxies appear in a telescope at the 10th magnitude. SN 2004gt was a type Ic supernova that erupted on December 12, 2004. The progenitor was not identified from older images of the galaxy, and is either a type WC Wolf-Rayet star with a mass over 40 times that of the Sun, or a star 20 to 40 times as massive as the Sun in a binary star system. SN 2007sr was a Type Ia supernova event that peaked in brightness on  December 14, 2007. The galaxy has been identified as a good place to take detailed images in case of further supernovae.

text: The most common red giants are stars on the red-giant branch (RGB) that are still fusing hydrogen into helium in a shell surrounding an inert helium core. Other red giants are the red-clump stars in the cool half of the horizontal branch, fusing helium into carbon in their cores via the triple-alpha process; and the asymptotic-giant-branch (AGB) stars with a helium burning shell outside a degenerate carbon–oxygen core, and a hydrogen burning shell just beyond that.

text: Operation Redwing was a United States series of 17 nuclear test detonations from May to July 1956.  They were conducted at Bikini and Enewetak atolls. The entire operation followed Project 56 and preceded Project 57. The primary intention was to test new, second-generation thermonuclear devices. Also tested were fission devices intended to be used as primaries for thermonuclear weapons, and small tactical weapons for air defense. Redwing demonstrated the first US airdrop of a deliverable hydrogen bomb - test Cherokee. Because the yields for many tests at Operation Castle in 1954 were dramatically higher than predictions, Redwing was conducted using an "energy budget" - there were limits to the total amount of energy released, and the amount of fission yield was also strictly controlled. Fission, primarily "fast" fission of the natural uranium tamper surrounding the fusion capsule, greatly increases the yield of thermonuclear devices, and contributes the vast majority of the fallout - fusion being a relatively clean reaction.

text: The light curves for type II supernovae are characterised by a much slower decline than type I, on the order of 0.05 magnitudes per day, excluding the plateau phase. The visual light output is dominated by kinetic energy rather than radioactive decay for several months, due primarily to the existence of hydrogen in the ejecta from the atmosphere of the supergiant progenitor star.  In the initial explosion this hydrogen becomes heated and ionised.  The majority of type II supernovae show a prolonged plateau in their light curves as this hydrogen recombines, emitting visible light and becoming more transparent.  This is then followed by a declining light curve driven by radioactive decay although slower than in type I supernovae, due to the efficiency of conversion into light by all the hydrogen.

text: Even planets in more stable orbits of a binary star system would suffer other kinds of problems according to her such as climatic problems. As an example, a planet in a binary star system orbiting the larger star would be drawn closer to its gravitational field, causing the planet to endure heat of great temperatures during this period. As the planet passes its larger star and reaches the orbit of its smaller star, the gravitational field of that star would give the planet more distance from it. The distance (perhaps along with the smaller solar projection of the star) would send the planet into extreme frigid temperatures.

text: Sadhus (Hindu ascetics) still meditate beneath sacred fig trees, and Hindus do pradakshina (circumambulation, or meditative pacing) around the sacred fig tree as a mark of worship. Usually seven pradakshinas are done around the tree in the morning time chanting "vriksha rajaya namah", meaning "salutation to the king of trees." It claimed that the 27 stars (constellations) constituting 12 houses (rasis) and 9 planets are specifically represented precisely by 27 trees—one for each star. The Bodhi Tree is said to represent Pushya (Western star name γ, δ and θ Cancri in the Cancer constellation).

text: The systematic, careful collection of measurements or counts of relevant quantities is often the critical difference between pseudo-sciences, such as alchemy, and science, such as chemistry or biology. Scientific measurements are usually tabulated, graphed, or mapped, and statistical manipulations, such as correlation and regression, performed on them. The measurements might be made in a controlled setting, such as a laboratory, or made on more or less inaccessible or unmanipulatable objects such as stars or human populations. The measurements often require specialized scientific instruments such as thermometers, spectroscopes, particle accelerators, or voltmeters, and the progress of a scientific field is usually intimately tied to their invention and improvement.

text: Linear high-energy accelerators use a linear array of plates (or drift tubes) to which an alternating high-energy field is applied. As the particles approach a plate they are accelerated towards it by an opposite polarity charge applied to the plate. As they pass through a hole in the plate, the polarity is switched so that the plate now repels them and they are now accelerated by it towards the next plate. Normally a stream of "bunches" of particles are accelerated, so a carefully controlled AC voltage is applied to each plate to continuously repeat this process for each bunch.

text: A multiple star system consists of three or more stars that appear from Earth to be close to one another in the sky. This may result from the stars actually being physically close and gravitationally bound to each other, in which case it is a physical multiple star, or this closeness may be merely apparent, in which case it is an optical multiple star (meaning that the stars may appear to be close to each other when viewed from planet Earth, as they both seem to occupy the same point in the sky, but in reality, one star may be much further away from Earth than the other, which is not readily apparent unless one can view them from a different angle). Physical multiple stars are also commonly called multiple stars or multiple star systems.

text: Chemically peculiar stars (CP stars) are common among hot main sequence (hydrogen-burning) stars.  These hot peculiar stars have been divided into 4 main classes on the basis of their spectra, although two classification systems are sometimes used: metallic-lined (Am, CP1), Ap (CP2), mercury-manganese (HgMn, CP3) and helium-weak (He-weak, CP4). The class names provide a good idea of the peculiarities that set them apart from other stars on the main sequence.

text: A number of surveys have been performed to explore the connection between star formation and LINER activity.  If a connection can be found between star formation activity and LINER activity, then this strengthens the possibility that LINERs are powered by the hot gas found in star formation regions.  However, if star formation cannot be found in LINERs, then this definitively excludes star formation as powering LINER emission.

text: The Helmholtz Institute Jena was founded as an outstation of the GSI Helmholtzzentrum für Schwerionenforschung on June 25, 2009 and is located on the campus of the Friedrich Schiller University (FSU) in the city of Jena, Germany. Its purpose is to unite the research activities of the FSU in the fields of high intensity laser physics and x-ray spectroscopy with the expertise of the Deutsches Elektronen-Synchrotron (DESY), GSI Helmholtzzentrum für Schwerionenforschung and Helmholtz-Zentrum Dresden-Rossendorf in the fields of accelerator physics, laser physics and x-ray technology.The research profile of the Helmholtz Institute Jena is focused on the physics occurring at the border between conventional particle-acceleration technology and the fast-evolving field of laser-induced particle acceleration. (e.g. wakefield accelerator). It is concerned with advancing these new laser-induced accelerator concepts, as well as with the production and investigation of intense photon and particle beams, including their interaction with matter. Therefore the main activities of the institute are emphasized on the development of high intensity lasers, new concepts for laser-driven particle acceleration, x-ray spectroscopy and strong-field quantum electrodynamics, as well as on the physics of hot dense plasmas. Apart from that the Helmholtz Institute Jena aims to contribute to the further development of the research facilities at the Helmholtz center GSI, especially the future project FAIR (Facility for Antiproton and Ion Research), and DESY with the free-electron laser (FEL) photon sources FLASH and XFEL (European XFEL).In cooperation with the FSU Jena a completely diode-pumped laser system of the high energy petawatt class (HEPW) with the POLARIS laser is realized in the building of the Helmholtz Institute Jena. First measurements are done since 2008. Due to the missing last amplifier stage the pulse strength of 1 PW couldn't be reached yet.The graduate school "Research School for Advanced Photon Science" (RS-APS) was established at the Helmholtz Institute Jena in July 2012. The RS-APS supports up to 25 PhD students and provides a structured graduation program in cooperation with facilities of the FSU Jena and the Helmholtz Graduate School for Hadron and Ion Research (HGS-HIRe).

text: A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion (thermonuclear weapon). Both reactions release vast quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released the same amount of energy as approximately . The first thermonuclear ("hydrogen") bomb test released the same amount of energy as approximately .

text: The velocity vector can change in magnitude and in direction or both at once. Hence, the acceleration is the rate of change of the magnitude of the velocity vector plus the rate of change of direction of that vector. The same reasoning used with respect to the position of a particle to define velocity, can be applied to the velocity to define acceleration. The acceleration of a particle is the vector defined by the rate of change of the velocity vector.  The average acceleration of a particle over a time interval is defined as the ratio.

text: The spectrum of this star matches a stellar classification of G8 Ib, where the luminosity class of Ib indicates this is a lower luminosity supergiant star. Alternatively, it may be a star that has passed through the asymptotic giant branch stage and possesses a detached shell of dust. The estimated mass of this star is over 19 times the mass of the Sun, and it has expanded to a radius measured at around 105–175 times that of the Sun. Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified.

text: If the core is largely supported by electron degeneracy pressure, helium fusion will ignite on a timescale of days in a helium flash. In more massive stars, the ignition of helium fusion occurs relatively slowly with no flash. The nuclear power released during the helium flash is very large, on the order of 10 times the luminosity of the Sun for a few days and 10 times the luminosity of the Sun (roughly the luminosity of the Milky Way Galaxy) for a few seconds. However, the energy is absorbed by the stellar envelope and thus cannot be seen from outside the star. The energy released by helium fusion causes the core to expand, so that hydrogen fusion in the overlying layers slows and total energy generation decreases. The star contracts, although not all the way to the main sequence, and it migrates to the horizontal branch on the Hertzsprung–Russell diagram, gradually shrinking in radius and increasing its surface temperature.

text: Red giants are evolved from main-sequence stars with masses in the range from about  to around .  When a star initially forms from a collapsing molecular cloud in the interstellar medium, it contains primarily hydrogen and helium, with trace amounts of "metals" (in stellar structure, this simply refers to any element that is not hydrogen or helium i.e. atomic number greater than 2). These elements are all uniformly mixed throughout the star. The star reaches the main sequence when the core reaches a temperature high enough to begin fusing hydrogen (a few million kelvin) and establishes hydrostatic equilibrium. Over its main sequence life, the star slowly converts the hydrogen in the core into helium; its main-sequence life ends when nearly all the hydrogen in the core has been fused. For the Sun, the main-sequence lifetime is approximately 10 billion years. More-massive stars burn disproportionately faster and so have a shorter lifetime than less massive stars.

text: Two systems introduced in historical catalogues remain in use to the present day. The first system comes from the German astronomer Johann Bayer's (1572–1625) Uranometria published in 1603 and is for bright stars. These are given a Greek letter followed by the genitive case of the constellation in which they are located; examples are Alpha Centauri or Gamma Cygni. The major problem with Bayer's naming system was the number of letters in the Greek alphabet (24). It was easy to run out of letters before running out of stars needing names, particularly for large constellations such as Argo Navis. Bayer extended his lists up to 67 stars by using lower-case Roman letters ("a" through "z") then upper-case ones ("A" through "Q"). Few of those designations have survived. It is worth mentioning, however, as it served as the starting point for variable star designations, which start with "R" through "Z", then "RR", "RS", "RT"..."RZ", "SS", "ST"..."ZZ" and beyond.

text: The 2003 Game's format was reverted to its classic East vs. West format. Dany Heatley scored four goals, tying an All-Star Game record, in addition to recording a shootout goal. Heatley also set the record for being the youngest player to score a hat-trick in the All-Star Game, a record previously held by the Edmonton Oilers' Wayne Gretzky. This shootout, the first of its kind in the NHL in the modern era, received an enthusiastic, frenzied response from the crowd when it was announced, and carried on during the event. This was influential in the later decision to decide regular season games tied after overtime with a shootout, thus eliminating tie games.

The most active region of star formation, located in the northeast arm, shows a stellar flux around 1,000 times higher than in the central region, though this may be affected by the density of stellar dust in the core. The extended portions of both arms exhibit young star cluster formations with ages ranging from one to one hundred million years. Star formation rates in the northeast extended arm are twice that of the southwest extended arm, and five times the formation rate in the sections of the arms closer to the central region.

text: Vivian E. Robson notes that many of the traditional constellations outside of the zodiac constellations occupy large degrees of arc and typically compass several of the tropical zodiac signs.  Ptolemy referred to stars by reference to the anatomy or parts of the constellations in which they appeared; thus Arcturus he named the "right knee of Boötes".  Most of the Western names of stars, such as Algol or Betelgeuse, are Arabic in origin.  In 1603 the Augsburg lawyer-uranographer Johann Bayer introduced the current classificatory system for the brighter stars, in which stars are identified as belonging to their constellations by Greek letters, in (roughly) descending order of brightness; so that Regulus, brightest star in Leo, is called α Leonis, the brightest star of the Lion.

text: The focus for discovering new exoplanets has been on sun-like stars. The catalog of more than 400 exoplanets has proved that these searches are successful, because exoplanets of various sizes have been discovered. However, other star types are also a likely place to discover new exoplanets. New research, announced at the meeting, confirms that planet formation is a natural by-product of star formation. Planet formation occurs even around stars much more massive than the Sun. However, the life of the stars which the planets orbit are so short that intelligent extraterrestrial life is not very likely. A and B type stars were surveyed for the research which involved NASA's Spitzer Space Telescope, the Two Micron All-Sky Survey, and astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) and the National Optical Astronomy Observatory (NOAO).

text: Alpha Centauri is the name given to what appears as a single star to the naked eye and the brightest star in the southern constellation of Centaurus. At −0.27 apparent visual magnitude (calculated from A and B magnitudes), it is fainter only than Sirius and Canopus. The next-brightest star in the night sky is Arcturus. Alpha Centauri is a multiple-star system, with its two main stars being Alpha Centauri A  and Alpha Centauri B , usually defined to identify them as the different components of the binary . A third companion—Proxima Centauri (or Proxima or )—has a distance much greater than the observed separation between stars A and B and is probably gravitationally associated with the AB system. As viewed from Earth, it is located at an angular separation of 2.2° from the two main stars. Proxima Centauri would appear to the naked eye as a separate star from  if it were bright enough to be seen without a telescope. Alpha Centauri AB and Proxima Centauri form a visual double star. Direct evidence that Proxima Centauri has an elliptical orbit typical of binary stars has yet to be found. Together, the three components make a triple star system, referred to by double-star observers as the triple star (or multiple star), .

text: Modelling suggests that at near-solar metallicity, stars with an initial mass around  will explode as a supernova while in the LBV stage of their lives. They will be post-red-supergiants with luminosities a few hundred thousand times that of the Sun. The supernova is expected to be of type II, most likely type IIb, although possibly type IIn due to episodes of enhanced mass loss that occur as an LBV and in the yellow-hypergiant stage.

text: A flare star is a variable star that can undergo unpredictable dramatic increases in brightness for a few minutes. It is believed that the flares on flare stars are analogous to solar flares in that they are due to the magnetic energy stored in the stars' atmospheres. The brightness increase is across the spectrum, from X rays to radio waves. The first known flare stars (V1396 Cygni and AT Microscopii) were discovered in 1924. However, the best-known flare star is UV Ceti, discovered in 1948. Today similar flare stars are classified as UV Ceti type variable stars (using the abbreviation UV) in variable star catalogs such as the General Catalogue of Variable Stars.

text: When he arrived at the Comisión Chilena de Energía Nuclear, he started to work in plasmas driven by small transient electrical discharges and small pulsed power devices: z-pinch, capillary discharges and plasma focus. His work has contributed to understand that it is possible to scale the plasma focus in a wide range of energies and sizes, keeping the same value of ion density, magnetic field, plasma sheath velocity, Alfvén speed and the quantity of energy per particle. Therefore, fusion reactions are possible to be obtained in ultra-miniaturized devices (driven by generators of 0.1J for example), as well as they are obtained in bigger devices (driven by generators of 1MJ). However, the stability of the plasma pinch highly depends on the size and energy of the device. A rich plasma phenomenology it has been observed in the table-top plasma focus devices developed by Soto´s group: filamentary structures, toroidal singularities, plasma bursts and plasma jets generations. In addition, possible applications are explored using these kind of small plasma devices: development of portable generator as non-radioactive sources of neutrons and x-rays for field applications, pulsed radiation applied to biological studies, plasma focus as neutron source for nuclear fusion-fission hybrid reactors, and the use of plasma focus devices as plasma accelerators for studies of materials under intense fusion-relevant pulses.

text: Binary systems containing neutron stars often emit X-rays, which are emitted by hot gas as it falls towards the surface of the neutron star.  The source of the gas is the companion star, the outer layers of which can be stripped off by the gravitational force of the neutron star if the two stars are sufficiently close.  As the neutron star accretes this gas its mass can increase; if enough mass is accreted the neutron star may collapse into a black hole.

text: In April 2007, astronomers announced that the Swedish-built Odin satellite had made the first detection of clouds of molecular oxygen in space, following observations in the constellation Ophiuchus. The supernova of 1604 was first observed on 9 October 1604, near θ Ophiuchi. Johannes Kepler saw it first on 16 October and studied it so extensively that the supernova was subsequently called Kepler's Supernova. He published his findings in a book titled De stella nova in pede Serpentarii (On the New Star in Ophiuchus' Foot). Galileo used its brief appearance to counter the Aristotelian dogma that the heavens are changeless. In 2009 it was announced that GJ 1214, a star in Ophiuchus, undergoes repeated, cyclical dimming with a period of about 1.5 days consistent with the transit of a small orbiting planet. The planet's low density (about 40% that of Earth) suggests that the planet may have a substantial component of low-density gas—possibly hydrogen or steam. The proximity of this star to Earth (42 light years) makes it a tempting target for further observations. In April 2010, the naked-eye star ζ Ophiuchi was occulted by the asteroid 824 Anastasia.

text: Blue supergiants newly evolved from the main sequence have extremely high luminosities, high mass loss rates, and are generally unstable.  Many of them become luminous blue variables with episodes of extreme mass loss.  Lower mass blue supergiants continue to expand until they become red supergiants.  In the process they obviously must spend some time as yellow supergiants or yellow hypergiants, but this expansion occurs in just a few thousand years and so these stars are rare.  Higher mass red supergiants blow away their outer atmospheres and evolve back to blue supergiants, and possibly onwards to Wolf–Rayet stars.  Depending on the exact mass and composition of a red supergiant, it can execute a number of blue loops before either exploding as a type II supernova or finally dumping enough of its outer layers to become a blue supergiant again, less luminous than the first time but more unstable.  If such a star can pass through the yellow evolutionary void it is expected that it becomes one of the lower luminosity LBVs.

text: Another eclipsing binary in Auriga, part of the Haedi asterism with Eta Aurigae, is Zeta Aurigae (Sadatoni), an eclipsing binary star at a distance of 776 light-years with a period of 2 years and 8 months. It has an absolute magnitude of −2.3. The primary is an orange-hued K5II-type star (K-type bright giant) and the secondary is a smaller blue star similar to Regulus; its period is 972 days. The secondary is a B7V-type star, a B-type main-sequence star. Zeta Aurigae's maximum magnitude is 3.7 and its minimum magnitude is 4.0. The full eclipse of the small blue star by the orange giant lasts 38 days, with two partial phases of 32 days at the beginning and end. The primary has a diameter of 150 D and a luminosity of ; the secondary has a diameter of 4 D and a luminosity of . Zeta Aurigae was spectroscopically determined to be a double star by Antonia Maury in 1897 and was confirmed as a binary star in 1908 by William Wallace Campbell. The two stars orbit each other about  apart. Zeta Aurigae is moving away from Earth at a rate of  per second. The second of the two Haedi or "Kids" is Eta Aurigae, a B3 class star located 243 light-years from Earth with a magnitude of 3.17.

text: Volcanologists use the regular, predictable Earth tide movements to calibrate and test sensitive volcano deformation monitoring instruments. The tides may also trigger volcanic events.Seismologists have determined that microseismic events are correlated to tidal variations in Central Asia (north of the Himalayas).The semidiurnal amplitude of terrestrial tides can reach about 55 cm at the equator which is important in GPS, VLBI, and SLR measurements. Also to make precise astronomical angular measurements requires knowledge of the Earth's rate of rotation (length of day, precession, and nutation), which is influenced by earth tides (so-called pole tide). Terrestrial tides also need to be taken in account in the case of some particle physics experiments.For instance, at the CERN or SLAC, the very large particle accelerators were designed while taking terrestrial tides into account for proper operation. Among the effects that need to be taken into account are circumference deformation for circular accelerators and particle beam energy.

text: The instability strip intersects the main sequence in the region of A and F stars (1–2 solar mass ()) and extends to G and early K bright supergiants (early M if RV Tauri stars at minimum are included). The lower part of instability strip appears as the Hertzsprung gap on the Hertzsprung–Russell diagram.  Above the main sequence, the vast majority of stars in the instability strip are variable.  Where the instability strip intersects the main sequence, the vast majority of stars are stable, but there are some variables, including the roAp stars.

text: Three star systems have been discovered to have exoplanets. HD 111232 is a yellow main sequence star around 78% as massive as the Sun around 95 light-years distant. It has a planet (HD 111232 b) around 6.8 times the mass of Jupiter that has an orbital period of around 1143 days. HD 112410 is a yellow giant of spectral type G8III located around 439 light-years distant. With around 1.54 times the mass of our Sun, it is cooling and expanding along the red giant branch, having left the main sequence after exhausting its core supply of hydrogen fuel. It has a substellar companion calculated to have a mass 9.2 times that of Jupiter and an orbital period of 124.6 days at a distance of approximately 0.57 AU. Yet another member of the Lower Centaurus Crux subgroup, HD 100546 is a young blue-white Herbig Ae/Be star of spectral type B9V that has yet to settle on the main sequence—the closest of these stars to Earth at around 320 light-years distant. It is surrounded by a circumstellar debris disk from a distance of 0.2 to 4 AU, and again from 13 AU out to a few hundred AU, with evidence for a protoplanet forming at a distance of around 47 AU. There is a gap between 4 and 13 AU, which appears to contain a large planet around 20 times the mass of Jupiter, although further examination of the disk profile indicates it might be a more massive object such as a brown dwarf or more than one planet. LP 145-141 is a white dwarf located 15 light-years distant—the fourth-closest to the Solar System. It is considered a good candidate to look for Jupiter-like planets, on account if its proximity and mass.

text: The McDonald's All-American designation began in 1977 with the selection of the inaugural team. That year, the All-Americans played in an all-star game against a group of high school stars from the Washington, D.C. area.  The following year, the McDonald's game format of East vs. West was begun with a boys contest. In 2002, with the addition of a girls contest, the current girl-game / boy-game doubleheader format began.

text: One or more of the particles may each be subject to one or more holonomic constraints, such a constraint is described by an equation of the form f(r, t) = 0. If the number of constraints in the system is C, then each constraint has an equation, f(r, t) = 0, f(r, t) = 0, ... f(r, t) = 0, each could apply to any of the particles. If particle k is subject to constraint i, then f(r, t) = 0. At any instant of time, the coordinates of a constrained particle are linked together and not independent. The constraint equations determine the allowed paths the particles can move along, but not where they are or how fast they go at every instant of time. Nonholonomic constraints depend on the particle velocities, accelerations, or higher derivatives of position. Lagrangian mechanics can only be applied to systems with holonomic constraints. Three examples are when the constraint equations are nonintegrable, when the constraints have inequalities, or with complicated non-conservative forces like friction. Nonholonomic constraints require special treatment, and one may revert to Newtonian mechanics, or use other methods.

text: Beta Boötis (β Boötis, abbreviated Beta Boo, β Boo), also named Nekkar, is a star in the northern constellation of Boötes. It has an apparent visual magnitude of 3.5, making it one of the brighter members of the constellation. In the modern constellation, it marks the head of Boötis the herdsman. Based upon parallax measurements, this star is approximately  from the Sun. At that distance, the magnitude of the star is reduced by 0.06 from extinction caused by intervening gas and dust.

text: Howes began making silent pictures in Hollywood in 1923. At this stage of his career his youthful good looks led to him supporting or co-starring with many of filmdoms well-known and beautiful female stars of the time i.e. Marie Prevost, Clara Bow, Mildred Harris, Marjorie Daw, Viola Dana, Louise Fazenda and Virginia Brown Faire. He also appeared in low budget pictures with lesser known female stars i.e. Gladys Hulette, Ruth Dwyer, Carmelita Geraghty, Ethel Shannon and Alice Calhoun. Indeed, many of Howes's silent pictures are 'racing car-romance' movies, the kind Wallace Reid made popular before his untimely death in 1923. Howes seems to have picked up where Wally Reid left off and in fact Howes resembles Wally in looks or more precisely a cross between Wallace Reid and Neil Hamilton. The majority of Howes silents were produced by Harry Joe Brown(who also directed) and released through the Rayart company. Al Rogell directed a lot of them. The studios Howes worked for in the silent era were FBO, Warner Brothers, Fox, Paramount and Universal.

text: A small subset of Miras appear to change their period over time—the period increases or decreases by a substantial amount (up to a factor of three) over the course of several decades to a few centuries. This is believed to be caused by thermal pulses, where the helium shell reignites the outer hydrogen shell. This changes the structure of the star, which manifests itself as a change in period. This process is predicted to happen to all Mira variables, but the relatively short duration of thermal pulses (a few thousand years at most) over the asymptotic giant branch lifetime of the star (less than a million years), means we only see it in a few of the several thousand Mira stars known, possibly in R Hydrae.  Most Mira variables do exhibit slight cycle-to-cycle changes in period, probably caused by nonlinear behaviour in the stellar envelope including deviations from spherical symmetry.

text: The gravitational collapse of a star is a natural process that can produce a black hole. It is inevitable at the end of the life of a star, when all stellar energy sources are exhausted. If the mass of the collapsing part of the star is below the Tolman–Oppenheimer–Volkoff (TOV) limit for neutron-degenerate matter, the end product is a compact star — either a white dwarf (for masses below the Chandrasekhar limit) or a neutron star or a (hypothetical) quark star.  If the collapsing star has a mass exceeding the TOV limit, the crush will continue until zero volume is achieved and a black hole is formed around that point in space.

text: Other note-worthy research the South African Astronomical Observatory has achieved using SALT include the discovery of a class of stars known as "polar", or a pair of stars. The "polar" binary star system, where a compactor star called a "white dwarf" whose volume has shrunk about one millionth of a star like our sun. Studies using SALT concluded that these polar binary star systems take only an hour and a half to complete an orbit. Also, the SALT telescope allows scientists to study the rapid brightness changes in exotic stars.

text: M38 is a diffuse open cluster at a distance of 3,900 light-years, the least concentrated of the three main open clusters in Auriga; it is classified as a Trumpler Class II 2 r or III 2 r cluster because of this. It appears as a cross-shaped or pi-shaped object in a telescope and contains approximately 100 stars; its overall magnitude is 6.4. M38, like M36, was discovered by Guillaume Le Gentil in 1749. It has an apparent diameter of approximately 20 arcseconds and a true diameter of about 25 light-years. Unlike M36 or M37, M38 has a varied stellar population. The majority of the population consists of A and B type main sequence stars, the B type stars being the oldest members, and a number of G type giant stars. One yellow-hued G type star is the brightest star in M38 at a magnitude of 7.9. The brightest stars in M38 are magnitude 9 and 10. M38 is accompanied by NGC 1907, a smaller and dimmer cluster that lies half a degree south-southwest of M38; it is at a distance of 4,200 light-years. The smaller cluster has an overall magnitude of 8.2 and a diameter of 6.0 arcminutes, making it about a third the size of M38. However, NGC 1907 is a rich cluster, classified as a Trumpler Class I 1 m n cluster. It has approximately 12 stars of magnitude 9–10, and at least 25 stars of magnitude 9–12.

text: Psi Cancri (ψ Cnc, ψ Cancri) is a star in the constellation Cancer.  It is classified as an orange K-type giant, with an apparent magnitude of +6.44.  It is approximately 1030 light years from Earth. Its designation is unusual as it is one of a very few stars which have a Bayer designation and are not in the Bright Star Catalog.

text: Both stars have a matching stellar classification of B9.5 III, indicating that they are massive, B-type giant stars that have exhausted the supply of hydrogen at their cores and evolved away from the main sequence of stars like the Sun. Hummel et al. (1996) gave the primary component, θ Aql A, an estimated mass of 3.6 solar, a radius 4.8 the Sun's, and 278 the luminosity of the Sun. For the secondary component, θ Aql B, they give the corresponding parameters as 2.9 times the mass, 2.4 times the radius and 68 times the luminosity of the Sun. Based upon their estimated parameters, Kaler (2008) suggests that θ Aql A is actually a subgiant star, while θ Aql B is a main sequence star.

text: During the red giant phase of stellar evolution in stars with less than 2.0  the nuclear fusion of hydrogen ceases in the core as it is depleted, leaving a helium-rich core. While fusion of hydrogen continues in the star’s shell causing a continuation of the accumulation of helium ash in the core, making the core denser, the temperature still is unable to reach the level required for helium fusion, as happens in more massive stars. Thus the thermal pressure from fusion is no longer sufficient to counter the gravitational collapse and create the hydrostatic equilibrium found in most stars. This causes the star to start contracting and increasing in temperature until it eventually becomes compressed enough for the helium core to become degenerate matter. This degeneracy pressure is finally sufficient to stop further collapse of the most central material but the rest of the core continues to contract and the temperature continues to rise until it reaches a point () at which the helium can ignite and start to fuse.

text: Despite the up-or-out system, under President José Sarney the army became top-heavy as generals began to occupy many positions that previously had been reserved for colonels. In 1991 there were fifteen four-stars, forty three-stars, and 110 two-stars generals. The figure for four-stars generals did not include four who were Ministers in the Superior Military Court (Superior Tribunal Militar—STM). Thus, in the mid-1990s the army sought to reduce the number of active-duty generals. In 2014, there are fifteen four-stars, forty five three-stars, and eighty nine two-stars generals in active service.

text: In general, the more massive a star is, the shorter its lifespan on the main sequence. After the hydrogen fuel at the core has been consumed, the star evolves away from the main sequence on the HR diagram. The behavior of a star now depends on its mass, with stars below 0.23  becoming white dwarfs directly, whereas stars with up to ten solar masses pass through a red giant stage. More massive stars can explode as a supernova, or collapse directly into a black hole.

text: Four star systems are known to harbour planets. HD 330075 is a sunlike star around 164 light-years distant that is orbited by a hot Jupiter every 3.4 days. Announced in 2004, it was the first planet discovered by the HARPS spectrograph. HD 148156 is a star 168 ± 7 light-years distant. Slightly larger and hotter than the Sun, it was found to have a roughly Jupiter-size planet with an orbital period of 2.8 years. HD 143361 is a binary star system composed of a sunlike star and a faint red dwarf separated by 30.9 AU. A planet roughly triple the mass of Jupiter orbits the brighter star every 1057± 20 days. HD 142415 is approximately 113 light-years distant and has a Jupiter-sized planet with an orbital period of around 386 days.

text: Supergiant luminosity classes are easy to determine and apply to large numbers of stars, but they group a number of very different types of star into a single category.  An evolutionary definition restricts the term supergiant to those massive stars which start core helium fusion without developing a degenerate helium core and without undergoing a helium flash.  They will universally go on to burn heavier elements and undergo core collapse resulting in a supernova.

text: A low-mass X-ray binary (LMXB) is a binary star system where one of the components is either a black hole or neutron star.  The other component, a donor, usually fills its Roche lobe and therefore transfers mass to the compact star.  The donor is less massive than the compact object, and can be on the main sequence, a degenerate dwarf (white dwarf), or an evolved star (red giant).  Approximately two hundred LMXBs have been detected in the Milky Way, and of these, thirteen LMXBs have been discovered in globular clusters.  The Chandra X-ray Observatory has revealed LMXBs in many distant galaxies.

text: Gemini is dominated by Castor and Pollux, two bright stars that appear relatively very closely together forming an o shape, encouraging the mythological link between the constellation and twinship. The twin above and to the right (as seen from the Northern Hemisphere) is Castor, whose brightest star is α Gem; it is a second magnitude star and represents Castor's head. The twin below and to the left is Pollux, whose brightest star is β Gem (more commonly called Pollux); it is of the first magnitude and represents Pollux's head. Furthermore, the other stars can be visualized as two parallel lines descending from the two main stars, making it look like two figures.

text: Grus (, or colloquially ) is a constellation in the southern sky. Its name is Latin for the crane, a type of bird. It is one of twelve constellations conceived by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman. Grus first appeared on a 35-cm (14 in) diameter celestial globe published in 1598 in Amsterdam by Plancius and Jodocus Hondius and was depicted in Johann Bayer's star atlas Uranometria of 1603.  French explorer and astronomer Nicolas Louis de Lacaille gave Bayer designations to its stars in 1756, some of which had been previously considered part of the neighbouring constellation Piscis Austrinus. The constellations Grus, Pavo, Phoenix and Tucana are collectively known as the "Southern Birds".

text: In a neutron star less massive than the limit, the weight of the star is balanced by short-range repulsive neutron-neutron interactions mediated by the strong force and also by the quantum degeneracy pressure of neutrons, preventing collapse.  If its mass is above the limit, the star will collapse to some denser form.  It could form a black hole, or change composition and be supported in some other way (for example, by quark degeneracy pressure if it becomes a quark star).  Because the properties of hypothetical, more exotic forms of degenerate matter are even more poorly known than those of neutron-degenerate matter, most astrophysicists assume, in the absence of evidence to the contrary, that a neutron star above the limit collapses directly into a black hole.

text: The proper motions of stars near the center of our own Milky Way provide strong observational evidence that these stars are orbiting a supermassive black hole. Since 1995, astronomers have tracked the motions of 90 stars orbiting an invisible object coincident with the radio source Sagittarius A*. By fitting their motions to Keplerian orbits, the astronomers were able to infer, in 1998, that a 2.6 million  object must be contained in a volume with a radius of 0.02 light-years to cause the motions of those stars. Since then, one of the stars—called S2—has completed a full orbit. From the orbital data, astronomers were able to make refine the calculations of the mass to 4.3 million  and a radius of less than 0.002 lightyears for the object causing the orbital motion of those stars. The upper limit on the object's size is still too large to test whether it is smaller than its Schwarzschild radius; nevertheless, these observations strongly suggest that the central object is a supermassive black hole as there are no other plausible scenarios for confining so much invisible mass into such a small volume. Additionally, there is some observational evidence that this object might possess an event horizon, a feature unique to black holes.

text: A blitzar is thought to start from a neutron star with a mass that would cause it to collapse into a black hole if it were not rapidly spinning.  Instead, the neutron star spins fast enough so that its centrifugal force keeps the collapse from happening.  This makes the neutron star a typical but doomed pulsar.  Over a few million years, the pulsar's strong magnetic field radiates energy away and slows its spin.  Eventually the weakening centrifugal force is no longer able to stop the pulsar from its transformation into a black hole.  At this moment of blitzar formation, part of the pulsar's magnetic field outside the black hole is suddenly cut off from its vanished source.  This magnetic energy is instantly transformed into a burst of wide spectrum radio energy. As of January 20, 2015, seven  radio events detected so far might represent such possible collapses; they are projected to occur every 10 seconds within the observable universe.  Because the magnetic field had previously cleared the surrounding space of gas and dust, there is no nearby material that will fall into the new black hole.  Thus there is no burst of X-rays or gamma rays that usually happens when other black holes form.

text: K-type main-sequence stars are smaller than the Sun and live longer, remaining on the main sequence 15 to 30 billion years compared to the Sun's estimated 10 billion. Despite these properties, the small M-type and K-type stars can pose a threat to life. Because of their high stellar activity at the beginning of their lives, they emit strong solar winds. The duration of this period is inversely linked to the size of the star. However, because of the uncertainty of the age of Kepler-442, it is likely it may have passed this stage, making Kepler-442b potentially more suitable for habitability. Because it is closer to its star than Earth is to the Sun, the planet will probably rotate much more slowly than Earth; its day could be weeks or months long (see Tidal effects on rotation rate, axial tilt and orbit). This is reflected on its orbital distance just outside of the point where the tidal interactions from its star would be strong enough to tidally locked.

text: Vega's spectral class is A0V, making it a blue-tinged white main sequence star that is fusing hydrogen to helium in its core. Since more massive stars use their fusion fuel more quickly than smaller ones, Vega's main-sequence lifetime is roughly one billion years, a tenth of the Sun's. The current age of this star is about 455 million years, or up to about half its expected total main-sequence lifespan. After leaving the main sequence, Vega will become a class-M red giant and shed much of its mass, finally becoming a white dwarf. At present, Vega has more than twice the mass of the Sun and its full luminosity is about 40 times the Sun's value. However, because of its high rate of rotation, the pole is considerably brighter than the equator. Because it is seen nearly pole-on, its apparent luminosity from Earth is notably higher, about 57 times the Sun's value. If Vega is variable, then it may be a Delta Scuti type with a period of about 0.107 days.

text: Reticulum II (or Reticulum 2) is an old dwarf galaxy in the Local Group. Reticulum II was discovered in 2015 by analysing images from the Dark Energy Survey. It is elongated, having an axis ratio of 0.6. The size is given by a half light distance of 30 pc. This is too large for it to be a globular cluster. Magnitude M is -2.7. The distance is 30 kpc. The galaxy contains some blue horizontal branch stars. Other features visible are a main sequence, and a main sequence turn off, and a red giant branch. It has an unusual enhancement of r-process elements; meaning that gold and europium are extra common in the brightest stars in the galaxy. The implication of the unusual enrichment in elements heavier than zinc, is that the r-process is very rare, and only happened once in this galaxy, possibly by the collision of two neutron stars.

text: Marking the herdsman's head is Beta Boötis, or Nekkar, a yellow giant of magnitude 3.5 and spectral type G8IIIa. Like Arcturus, it has expanded and cooled off the main sequence—likely to have lived most of its stellar life as a blue-white B-type main sequence star. Its common name comes from the Arabic phrase for "ox-driver". It is 219 light-years away and has a luminosity of . Located 86 light-years distant, Gamma Boötis, or Seginus, is a white giant star of spectral class A7III, with a luminosity 34 times and diameter 3.5 times that of the Sun. It is a Delta Scuti variable, ranging between magnitudes 3.02 and 3.07 every 7 hours. Thes stars are short period (six hours at most) pulsating stars that have been used as standard candles and as subjects to study astroseismology. Delta Boötis is a wide double star with a primary of magnitude 3.5 and a secondary of magnitude 7.8. The primary is a yellow giant that has cooled and expanded to 10.4 times the diameter of the Sun. Of spectral class G8IV, it is around 121 light-years away, while the secondary is a yellow main sequence star of spectral type G0V. The two are thought to take 120,000 years to orbit each other. Mu Boötis, known as Alkalurops, is a triple star popular with amateur astronomers. It has an overall magnitude of 4.3 and is 121 light-years away. Its name is from the Arabic phrase for "club" or "staff". The primary appears to be of magnitude 4.3 and is blue-white. The secondary appears to be of magnitude 6.5, but is actually a close double star itself with a primary of magnitude 7.0 and a secondary of magnitude 7.6. The secondary and tertiary stars have an orbital period of 260 years. The primary has an absolute magnitude of 2.6 and is of spectral class F0. The secondary and tertiary stars are separated by 2 arcseconds; the primary and secondary are separated by 109.1 arcseconds at an angle of 171 degrees. Nu Boötis is an optical double star. The primary is an orange giant of magnitude 5.0 and the secondary is a white star of magnitude 5.0. The primary is 870 light-years away and the secondary is 430 light-years.

text: Although it appears to be a single star to the naked eye, 61 Cygni is in fact a widely separated binary star system, composed of two K class (orange) main sequence stars, the brighter 61 Cygni A  and fainter 61 Cygni B, which have apparent magnitudes of 5.2 and 6.1, respectively. Both appear to be old-disk stars, with an estimated age that is older than the Sun. The system has a net space velocity of 108 km/s relative to the Sun, which results in the high proper motion across the sky. At a distance of just over 11 light-years, it is the 15th-nearest-known star system to the Earth (not including the Sun). 61 Cygni A is the fourth-nearest star that is visible to the naked eye for mid-latitude northern observers, after Sirius, Epsilon Eridani, and Procyon A. This system will make its closest approach at about 20,000 CE, when the separation from the Sun will be about 9 light-years.

text: A popular child-oriented derivative of the Milky Way bar known as 'Milky Way Magic Stars' is also sold in the UK and consists of small aerated chocolate star shapes. Originally, every star was engraved with a different smiley face, each representing one of the magic star characters portrayed on the packaging. The characters were: Pop Star, Jess Star, Bright Star, Super Star, Twinkle Star, Falling Star, Happy Star, Sport Star, Clever Star and Baby Star. Recently, however, the characters and their respective engravings have been discontinued, possibly to lower production costs.

text: Chattopadhyay returned to Lawrence Berkeley National Laboratory in 1984, where he led and defined the accelerator physics of the Advanced Light Source (ALS) and contributed to the conceptual design of the Superconducting Super Collider (SSC), pioneered the accelerator physics which underpinned the Berkeley-Stanford asymmetric B-factory (PEP-II) for CP-violation studies, and initiated the Berkeley FEL/Femtosecond X-ray Source and Laser-Plasma Acceleration development. He was a Senior Scientist, a Guest Professor, and the Founder/Director of the Center for Beam Physics at Berkeley, until his move to Thomas Jefferson National Accelerator Facility in 2001 as the Associate Laboratory Director for Accelerators, after 25 years at the University of California and Lawrence Berkeley National Lab.At Thomas Jefferson National Accelerator Facility, he made critical advancements in microwave superconducting linear accelerators leading the way to current and future grand instruments of science such as the high precision CEBAF and its 12 GeV upgrade for precision research in hadronic physics, Spallation Neutron Source at Oak Ridge National Laboratory, USA to advance neutron sciences and novel materials research, and the current superconducting version of the International Linear Collider, to name a few.His research at the Cockcroft Institute in UK included development of sources of “ultra-cold” relativistic free electron beams to advance coherent electron diffraction techniques; production of novel coherent and ultra-short pulses of photons (e.g. x-ray FELs); novel acceleration methods; investigation of photonic crystals and metamaterial structures for charged particle acceleration; novel high energy colliders; cavity search for “dark matter” and laboratory investigation of “dark energy” via atom interferometer techniques. Chattopadhyay is currently working for Fermilab and Northern Illinois University (NIU) acting as a distinctive professor and director of accelerator research.Having contributed to the conception, design, construction, commissioning and operation of numerous accelerators for particle and nuclear physics, photon and neutron sciences around the world, with significant research accomplishments in advanced particle and photon beam physics, and mentoring scientists around the world, in the developing nations in particular, in accelerator developments as a unifying global force among nations, Prof. Chattopadhyay is a frequently invited speaker and advisor at professional societies and government research agencies, serving on numerous editorial, advisory and review committees throughout the world.

text: Named Gorgonea Tertia, Rho Persei varies in brightness like Algol, but is a pulsating rather than eclipsing star. At an advanced stage of stellar evolution, it is a red giant that has expanded for the second time to have a radius around 150 times that of our Sun. Its helium has been fused into heavier elements and its core is composed of carbon and oxygen. It is a semiregular variable star of the Mu Cephei type, whose apparent magnitude varies between 3.3 and 4.0 with periods of 50, 120 and 250 days. The Double Cluster contains three even larger stars, each over 700 solar radii: S, RS, and SU Persei are all semiregular pulsating M-type supergiants. The stars are not visible to the naked eye;  SU Persei, the brightest of the three, has an apparent magnitude of 7.9 and thus is visible through binoculars. AX Persei is another binary star, the primary component is a red giant in an advanced phase of stellar evolution, which is transferring material onto an accretion disc around a smaller star. The star system is one of the few eclipsing symbiotic binaries, but is unusual because the secondary star is not a white dwarf, but an A-type star. DY Persei is a variable star that is the prototype of DY Persei variables, which are carbon-rich R Coronae Borealis variables that exhibit the variability of asymptotic giant branch stars. DY Persei itself is a carbon star that is too dim to see through binoculars, with an apparent magnitude of 10.6.

text: The first large proton synchrotron was the Cosmotron at Brookhaven National Laboratory, which accelerated protons to about 3 GeV (1953–1968). The Bevatron at Berkeley, completed in 1954, was specifically designed to accelerate protons to sufficient energy to create antiprotons, and verify the particle-antiparticle symmetry of nature, then only theorized. The Alternating Gradient Synchrotron (AGS) at Brookhaven (1960–) was the first large synchrotron with alternating gradient, "strong focusing" magnets, which greatly reduced the required aperture of the beam, and correspondingly the size and cost of the bending magnets. The Proton Synchrotron, built at CERN (1959–), was the first major European particle accelerator and generally similar to the AGS.

text: Current models indicate that matter at the surface of a neutron star is composed of ordinary atomic nuclei crushed into a solid lattice with a sea of electrons flowing through the gaps between them. It is possible that the nuclei at the surface are iron, due to iron's high binding energy per nucleon. It is also possible that heavy elements, such as iron, simply sink beneath the surface, leaving only light nuclei like helium and hydrogen. If the surface temperature exceeds 10 kelvin (as in the case of a young pulsar), the surface should be fluid instead of the solid phase that might exist in cooler neutron stars (temperature

text: The time until Betelgeuse explodes depends on the predicted initial conditions and on the estimate of the time already spent as a red supergiant.  The total lifetime from the start of the red supergiant phase to core collapse varies from about 300,000 years for a rotating  star, 550,000 years for a rotating  star, up to a million years for a non-rotating  star.  Given the estimated time since Betelgeuse became a red supergiant, estimates of its remaining lifetime range from a "best guess" of under 100,000 years for a non-rotating  model to far longer for rotating models or lower mass stars.  Betelgeuse's suspected birthplace in the Orion OB1 Association is the location of several previous supernovae. It is believed that runaway stars may be caused by supernovae, and there is strong evidence that OB stars μ Columbae, AE Aurigae and 53 Arietis all originated from such explosions in Ori OB1 2.2, 2.7 and 4.9 million years ago.

text: Before the Standard Model (SM) was developed in the 1970s (the key elements of the Standard Model known as quarks were proposed by Murray Gell-Mann and George Zweig in 1964), physicists observed hundreds of different kinds of particles in particle accelerators. These were organized into relationships on their physical properties in a largely ad-hoc system of hierarchies, not entirely unlike the way taxonomy grouped animals based on their physical features. Not surprisingly, the huge number of particles was referred to as the "particle zoo".

text: Trained  at Caltech as a nuclear physicist by Wm. A. Fowler, Clayton was well positioned to consider interactions of heavy nuclei with neutrons. These were believed by Fowler to govern the nucleosynthesis of nuclei heavier than iron. Clayton calculated the isotopic abundances produced by neutron irradiation of iron in stars for both the slow neutron capture S-process and the ra[id neutron capture R-process of heavy-element stellar nucleosynthesis (processes first defined by BFH). Clayton's two papers (1961 and 1965) on those topics demonstrated that solar-system abundances had been created not by a single neutron irradiation but as superpositions of abundance patterns established in presolar stars by differing neutron irradiations. His 1961 calculations of s-process abundance patterns, achieved by mathematical analysis rather than by computers, established Clayton as a nucleosynthesis theorist. They provided standard models that guided four decades of progress on the s process and on characteristics of the r process. In 1967 Clayton turned to the supernova origin of the abundances of elements that can be created in stars from hydrogen and helium alone. Those so-called primary nucleosynthesis nuclei having atomic weights between silicon and nickel (A=28-62) are very abundant. To understand their dramatic alternating abundances he tested a new conceptual idea that he named nuclear quasiequilibrium during silicon burning. The quasiequilibrium  concept did explain the observed numbers of isotopes in the A=28-62 mass range, which had previously been unsolved. Nuclear quasiequilibrium was at that time the grandest advance in theory of primary nucleosynthesis in supernovae since Hoyle's 1954 paper, whose focus it validated. Of extreme importance was its demonstration that supernova silicon burning should become profoundly radioactive because rapid quasiequilibrium between atomic weights A=44-62 is overwhelmingly of radioactive nuclei. Clayton's recent description in 2016 in terms of a secondary supernova machine of this important process with B. S. Meyer clarified that the intense radioactivity resulted from supernova shock waves forcing excess Coulomb energy into those nuclei.

The generation of nuclear energy in these low-density outer regions causes the protostar to swell, delaying the gravitational contraction of the object and postponing its arrival on the main sequence.

text: Arcturus had several names that described its significance to indigenous Polynesians. In the Society Islands, Arcturus, called Ana-tahua-taata-metua-te-tupu-mavae ("a pillar to stand by"), was one of the ten "pillars of the sky", bright stars that represented the ten heavens of the Tahitian afterlife. In Hawaii, the pattern of Boötes was called Hoku-iwa, meaning "stars of the frigate bird". This constellation marked the path for Hawaiiloa on his return to Hawaii from the South Pacific Ocean. The Hawaiians called Arcturus Hoku-leʻa. It was equated to the Tuamotuan constellation Te Kiva, meaning "frigate-bird", which could either represent the figure of Boötes or just Arcturus. However, Arcturus may instead be the Tuamotuan star called Turu. The Hawaiian name for Arcturus as a single star was likely Hoku-leʻa, which means "star of gladness", or "clear star". In the Marquesas Islands, Arcturus was probably called Tau-tou and was the star that ruled the month approximating January. The Maori and Moriori called it Tautoru, a variant of the Marquesan name and a name shared with Orion's Belt.

text: One suggested source of UHECR particles is their origination from neutron stars.  In young neutron stars with spin periods of <10ms, the magnetohydrodynamic (MHD) forces from the quasi-neutral fluid of superconducting protons and electrons existing in a neutron superfluid accelerate iron nuclei to UHECR velocities.  The magnetic field produced by the neutron superfluid in rapidly rotating stars creates a magnetic field of 10–10 tesla, at which point the neutron star is classified as a magnetar.  This magnetic field is the strongest in the observed universe and creates the relativistic MHD wind believed to accelerate iron nuclei remaining from the supernova to the necessary energy.

text: The binary system is classified as a white A-type main sequence dwarf with a mean apparent magnitude of +5.20.  Both component stars are detached main sequence stars which do not fill their Roche lobes.  Because the components regularly eclipse each other, 31 Camelopardalis is classified as a variable star and its brightness varies from magnitude +5.12 to +5.29 with a period of 2.93 days, which is the orbital period of the binary.

text: Reviews for the fifth episode were somewhat mixed. SFX magazine gave it 3.5 stars out of 5 and said that the episode had "some classic Red Dwarf moments ... but [was] not a classic episode." Similarly Starburst magazine gave it 6 stars out of 10, and said that "it’s clearly not the most complete of the recent episodes and there was plenty in there which felt like padding, but there was enough good stuff on show too to ensure it kept up the quality of the series." Radio Times liked the episode and said that "Red Dwarf is always at its finest when it jettisons the sci-fi plots and concentrates on Lister’s sense of loneliness", and reserved particular praise for Cat’s attempt at charades saying that it was "both excruciating and hilarious."

text: Particle physics (also high energy physics) is the branch of physics that studies the nature of the particles that constitute matter (particles with mass) and radiation (massless particles). Although the word "particle" can refer to various types of very small objects (e.g. protons, gas particles, the Tylertron, or even household dust), "particle physics" usually investigates the irreducibly smallest detectable particles and the irreducibly fundamental force fields necessary to explain them. The Tylertron is a newly discovered quark that was found using the Harritron particle accelerator. It is named after the highly renouned physics student, Taylor Robb. By our current understanding, these elementary particles are excitations of the quantum fields that also govern their interactions. The currently dominant theory explaining these fundamental particles and fields, along with their dynamics, is called the Standard Model. Thus, modern particle physics generally investigates the Standard Model and its various possible extensions, e.g. to the newest "known" particle, the Higgs boson, or even to the oldest known force field, gravity.

text: Bayer is most famous for his star atlas Uranometria Omnium Asterismorum ("Uranometry of all the asterisms"), which was first published in 1603 in Augsburg and dedicated to two prominent local citizens. This was the first atlas to cover the entire celestial sphere. It was based upon the work of Tycho Brahe and may have borrowed from Alessandro Piccolomini's 1540 star atlas, De le stelle fisse ("Of the fixed stars"), although Bayer included an additional 1,000 stars. The Uranometria introduced a new system of star designation which has become known as the Bayer designation. Bayer's atlas included twelve new constellations invented a few years earlier to fill in the far south of the night sky, which was unknown to ancient Greece and Rome.

text: Stars with an initial mass above about  quickly move away from the main sequence and increase somewhat in luminosity to become blue supergiants.  They cool and enlarge at approximately constant luminosity to become a red supergiant, then contract and increase in temperature as the outer layers are blown away.  They may "bounce" backwards and forwards executing one or more "blue loops", still at a fairly steady luminosity, until they explode as a supernova or completely shed their outer layers to become a Wolf–Rayet star.  Stars with an initial mass above about  are simply too luminous to develop a stable extended atmosphere and so they never cool sufficiently to become red supergiants.

text: Trapezia are usually very young, unstable systems. These are thought to form in stellar nurseries, and quickly fragment into stable multiple stars, which in the process may eject components as galactic high-velocity stars. They are named after the multiple star system known as the Trapezium Cluster in the heart of the Orion Nebula. Such systems are not rare, and commonly appear close to or within bright nebulae. These stars have no standard hierarchical arrangements, but compete for stable orbits, where the center of gravity is not fixed at some point but moves as the stars change their mutual positions. This relationship is called interplay. Such stars eventually settle down to a close binary with a distant companion, with the other star(s) previously in the system ejected into interstellar space at high velocities. Example of such events may explain the runaway stars that might have been ejected during a collision of two binary star groups or a multiple system. This event is credited with ejecting AE Aurigae, Mu Columbae and 53 Arietis at above 200 km·s and has been traced to the Trapezium cluster in the Orion Nebula some two million years ago.

text: Perseus is bordered by Aries and Taurus to the south, Auriga to the east, Camelopardalis and Cassiopeia to the north, and Andromeda and Triangulum to the west. Covering 615 square degrees, it ranks twenty-fourth of the 88 constellations in size. It appears prominently in the northern sky during the Northern Hemisphere's spring. Its main asterism consists of 19 stars. The constellation's boundaries, as set by Eugène Delporte in 1930, are defined by a 26-sided polygon. In the equatorial coordinate system, the right ascension coordinates of these borders lie between  and , while the declination coordinates are between  and . The International Astronomical Union (IAU) adopted the three-letter abbreviation "Per" for the constellation in 1922.

text: Johann Elert Bode renamed the constellation Telescopium Herschelii and omitted the smaller telescope constellation in his 1801 Uranographia  star atlas. In his atlas, the constellation depicted Herschel's earlier 7-foot telescope. It was ignored by some celestial cartographers such as Argelander in 1843, Proctor in 1876, Rosser in 1879 and Pritchard in 1885, yet did appear in two works of the 1890s. However, it was noted by Allen in 1899 that it was becoming obsolete. In 1930, when the official borders of the constellations were drawn up, its stars were absorbed into Auriga, Gemini and Lynx.

text: Stars with large proper motions tend to be nearby; most stars are far enough away that their proper motions are very small, on the order of a few thousandths of an arcsecond per year.  It is possible to construct nearly complete samples of high proper motion stars by comparing photographic sky survey images taken many years apart. The Palomar Sky Survey is one source of such images. In the past, searches for high proper motion objects were undertaken using blink comparators to examine the images by eye, but modern efforts use techniques such as image differencing to automatically search through digitized image data.  Because the selection biases of the resulting high proper motion samples are well-understood and well-quantified, it is possible to use them to construct an unbiased census of the nearby stellar population — how many stars exist of each true brightness, for example.  Studies of this kind show that the local population of stars consists largely of intrinsically faint, inconspicuous stars such as red dwarfs.

text: Star formation is taking place at a rate that is strongly correlated with the local gas density, and the rate per unit area is higher than in the neighboring Andromeda Galaxy. (The rate of star formation is about 3.4 Gyr pc in the Triangulum galaxy, compared to 0.74 in Andromeda.) The total integrated rate of star formation in the Triangulum galaxy is about . It is uncertain whether this net rate is currently decreasing or remaining constant.

text: The remnant's age is still uncertain. There is some agreement that the progenitor supernova happened between 3,000 and 30,000 years ago. Recent Chandra and XMM-Newton observationsidentified a plerion nebula, close to the remnant southern rim. The point source near the apex of the nebula is a neutron star, relic of a SN explosion. The location in a star forming region and the presence of a neutron star favor a Type II supernova,  the ultimate fate of a massive star, as the progenitor explosion.

text: The formation of the stars themselves is also unclear.  Standard stellar evolution models do not produce large luminous stars with essentially zero hydrogen.  The two main theories to explain these stars are both somewhat exotic, perhaps befitting such rare stars.  In one, a merger occurs between two white dwarf stars, one a Helium white dwarf and the other a carbon-oxygen white dwarf.  White dwarfs are naturally lacking in hydrogen and the resultant star would also lack that element.  The second model postulates a massive convective event at the onset of burning of an outer helium shell, causing the little remaining atmospheric Hydrogen to be turned over into the interior of the star.  It is possible that the diversity of R CrB stars is caused by a diversity of formation mechanisms, relating them to extreme helium stars and hydrogen-deficient carbon stars.

text: Astronomy provides a spectacular demonstration of the effect of the Pauli principle, in the form of white dwarf and neutron stars. In both bodies, atomic structure is disrupted by large gravitational forces, but the stars are held in hydrostatic equilibrium by degeneracy pressure, also known as Fermi pressure.  This exotic form of matter is known as degenerate matter. The immense gravitational force of a star's mass is normally held in equilibrium by thermal pressure caused by heat produced in thermonuclear fusion in the star's core. In white dwarfs, which do not undergo nuclear fusion, an opposing force to gravity is provided by electron degeneracy pressure. In neutron stars, subject to even stronger gravitational forces, electrons have merged with protons to form neutrons. Neutrons are capable of producing an even higher degeneracy pressure, neutron degeneracy pressure, albeit over a shorter range. This can stabilize neutron stars from further collapse, but at a smaller size and higher density than a white dwarf. Neutrons are the most "rigid" objects known; their Young modulus (or more accurately, bulk modulus) is 20 orders of magnitude larger than that of diamond. However, even this enormous rigidity can be overcome by the gravitational field of a massive star or by the pressure of a supernova, leading to the formation of a black hole.

text: The stars called white or degenerate dwarfs are made up mainly of degenerate matter: typically carbon and oxygen nuclei in a sea of degenerate electrons. White dwarfs arise from the cores of main-sequence stars and are therefore very hot when they are formed. As they cool they will redden and dim until they eventually become dark black dwarfs. White dwarfs were observed in the 19th century, but the extremely high densities and pressures they contain were not explained until the 1920s.

text: The visible component, Epsilon Aurigae A, is a semiregular pulsating post-asymptotic giant branch star belonging to the spectral class F0. This F-type star has around 135 to 190 times the diameter of the Sun, and is 70,000 to 80,000 times as luminous. (Reliable sources vary considerably in their estimates of both quantities.) If the star were in the position of the Sun, it would envelop Mercury and possibly Venus. F-type stars like Epsilon Aurigae tend to glow white and display strong ionized calcium absorption lines and weak hydrogen absorption lines; being a class above the Sun (which is a G-type star), F-type stars are typically hotter than sunlike stars. Other F-type stars include Procyon's primary star, the brightest star in the Canis Minor constellation; and Canopus, the second brightest star in the night sky and the brightest star in the Carina constellation.

text: MACHO-1997-BLG-41, commonly abbreviated as 97-BLG-41 or MACHO-97-BLG-41, was a gravitational microlensing event located in Sagittarius which occurred in July 1999. The source star is likely a giant or subgiant star of spectral type K located at a distance of around 8 kiloparsecs (26,000 light years). The lens star is a binary system approximately 10,000 light years away in the constellation Sagittarius. The two stars are separated from each other by about 0.9 AU and have an orbital period of around 1.5 years. The most likely mass of the system is about 0.3 times that of our Sun. Star A and star B are both red dwarfs.

text: Theoretical models show that Hot Jupiters and Hot Neptunes can evolve by hydrodynamic loss of their atmospheres to Mini-Neptunes (as it could be the Super-Earth GJ 1214 b), or even to rocky planets known as chthonian planets (after migrating towards the proximity of their parent star). The amount of the outermost layers that is lost depends on the size and the material of the planet and the distance from the star. In a typical system a gas giant orbiting 0.02 AU around its parent star loses 5–7% of its mass during its lifetime, but orbiting closer than 0.015 AU can mean evaporation of the whole planet except for its core.

text: White dwarfs with a spectrum that indicates high levels of metal contamination often possess a circumstellar disk. In the case of van Maanen 2, observations of the star at a wavelength of 24 μm do not show the infrared excess that might be generated by a dusty disk. Instead there is a noticeable deficit. The predicted flux at 24 μm is 0.23 mJy, whereas the measured value is . This deficit may be explained by collision-induced absorption in the atmosphere of the star. However, this is normally only known to happen with white dwarfs that have temperatures below 4,000 K, as a result of collisions between hydrogen molecules or between hydrogen molecules and helium.

This deficit may be explained by collision-induced absorption in the atmosphere of the star. However, this is normally only known to happen with white dwarfs that have temperatures below 4,000 K, as a result of collisions between hydrogen molecules or between hydrogen molecules and helium.

text: Stars are usually formed in the center of the galaxy. The center part of M51 appears to be undergoing a period of enhanced star formation. The present efficiency of star formation, defined as the ratio of mass of new stars to the mass of star-forming gas, is only ~1%, quite comparable to the global value for the Milky Way and other galaxies. It is estimated that the current high rate of star formation can last no more than another 100 million years or so.

text: It was in this region where the striking prevalence of filamentary cloud structures seen by ESA's Herschel Space Observatory was first noted. These filaments of cloud have dense "cores" of gas embedded within them—many of which are likely to gravitationally collapse and form stars. The Herschel results for this region, and subsequently reported results for other star-forming regions, imply that fragmentation of molecular-cloud filaments are fundamental to the star-formation process. The Herschel results for W40 and the Aquila Rift, compared to those for molecular clouds in the Polaris region, suggest that star-formation occurs when the linear density (mass per unit length) exceeds a threshold making them susceptible to gravitational instability. This accounts for the high star-formation rate in W40 and the Aquila Rift, in contrast to the low star-formation rate in the Polaris clouds. These observational results complement computer simulations of star-formation, which also emphasize the role that molecular-cloud filaments play in the birth of stars.

text: X-ray emission is expected from astronomical objects that contain extremely hot gasses at temperatures from about a million kelvin (K) to hundreds of millions of kelvin (MK). Although X-rays have been observed emanating from the Sun since the 1940s, the discovery in 1962 of the first cosmic X-ray source was a surprise. This source is called Scorpius X-1 (Sco X-1), the first X-ray source found in the constellation Scorpius. The X-ray emission of Scorpius X-1 is 10,000 times greater than its visual emission, whereas that of the Sun is about a million times less. In addition, the energy output in X-rays is 100,000 times greater than the total emission of the Sun in all wavelengths. Based on discoveries in this new field of X-ray astronomy, starting with Scorpius X-1, Riccardo Giacconi received the Nobel Prize in Physics in 2002. It is now known that such X-ray sources as Sco X-1 are compact stars, such as neutron stars or black holes. Material falling into a black hole may emit X-rays, but the black hole itself does not. The energy source for the X-ray emission is gravity. Infalling gas and dust is heated by the strong gravitational fields of these and other celestial objects.

text: However, there are some cautions about the study. First, the method used was actually an indirect method of calculation, and not Keplerian orbital estimation; the latter being a more precise estimate. It is unlikely for a quasar as luminous as S5 0014+81, which will just outshine the stars within its vicinity, thereby making estimates very inaccurate. Second, the spectra used is actually a long spectra, not accounting for the observed parameters. Third, the quasar is surrounded by a large accretion disc, a few parsecs in size, and it shines at 40% of its Eddington luminosity, the maximum luminosity through which radiation pressure is strong enough to blow up the disc away from the gravitational influence of the central black hole, so the observed characteristics are unknown due to intervening dust and gases. However, the possibility of an ultramassive black hole has not been ruled out entirely, since only a black hole of that mass can account for the observed power output of the quasar.

text: 57 Aquilae (abbreviated 57 Aql) is a double star in the constellation of Aquila. 57 Aquilae is its Flamsteed designation. The primary star has an apparent visual magnitude of 5.70, while the secondary is magnitude 6.48. The pair have an angular separation of 35.624 arcseconds and probably form a wide binary star system. The estimated distance of the first component is , while the second is at . However, the margin of errors for their respective distance estimates overlap, indicating a probability that they are actually located much closer to each other. Both stars are massive, B-type main sequence stars with rapid rotation rates.

text: On April 19, 2009, Lifetime aired Natalee Holloway, starring Tracy Pollan as Beth Holloway-Twitty, Grant Show as George "Jug" Twitty, Amy Gumenick as Natalee Holloway and Jacques Strydom as Joran van der Sloot. The film does not solve the case, but stages re-creations of various scenarios, based on the testimony of key players and suspects. The broadcast of the film attracted 3.2 million viewers, garnering the highest television ratings in the network's history at the time. Although it set ratings records for Lifetime, the movie was not received well by critic Alec Harvey of The Birmingham News. Harvey called the movie "sloppy and uneven, a forgettable look at the tragedy that consumed the nation's attention for months". However, Jake Meaney of PopMatters found the film to be surprisingly "calm and levelheaded", and praised Tracy Pollan's portrayal of Holloway. Holloway said that she was honored by Pollan's portrayal and that there "could not have been a better choice."

text: Early work in that area includes Turney and Pang who applied different methods for detecting the polarity of product reviews and movie reviews respectively. This work is at the document level. One can also classify a document's polarity on a multi-way scale, which was attempted by Pang and Snyder among others: Pang and Lee expanded the basic task of classifying a movie review as either positive or negative to predict star ratings on either a 3 or a 4 star scale, while Snyder performed an in-depth analysis of restaurant reviews, predicting ratings for various aspects of the given restaurant, such as the food and atmosphere (on a five-star scale). Even though in most statistical classification methods, the neutral class is ignored under the assumption that neutral texts lie near the boundary of the binary classifier, several researchers suggest that, as in every polarity problem, three categories must be identified. Moreover, it can be proven that specific classifiers such as the Max Entropy and the SVMs can benefit from the introduction of a neutral class and improve the overall accuracy of the classification. There are in principle two ways for operating with a neutral class. Either, the algorithm proceeds by first identifying the neutral language, filtering it out and then assessing the rest in terms of positive and negative sentiments, or it builds a three way classification in one step. This second approach often involves estimating a probability distribution over all categories (e.g. Naive Bayes classifiers as implemented by Python's NLTK kit). Whether and how to use a neutral class depends on the nature of the data: if the data is clearly clustered into neutral, negative and positive language, it makes sense to filter the neutral language out and focus on the polarity between positive and negative sentiments. If, in contrast, the data is mostly neutral with small deviations towards positive and negative affect, this strategy would make it harder to clearly distinguish between the two poles.

text: As only 30 to 40 per cent of the gas in the cloud core forms stars, the process of residual gas expulsion is highly damaging to the star formation process. All clusters thus suffer significant infant weight loss, while a large fraction undergo infant mortality. At this point, the formation of an open cluster will depend on whether the newly formed stars are gravitationally bound to each other; otherwise an unbound stellar association will result. Even when a cluster such as the Pleiades does form, it may only hold on to a third of the original stars, with the remainder becoming unbound once the gas is expelled. The young stars so released from their natal cluster become part of the Galactic field population.

text: In some spectroscopic binaries, spectral lines from both stars are visible and the lines are alternately double and single. Such a system is known as a double-lined spectroscopic binary (often denoted "SB2"). In other systems, the spectrum of only one of the stars is seen and the lines in the spectrum shift periodically towards the blue, then towards red and back again. Such stars are known as single-lined spectroscopic binaries ("SB1").

text: There are relatively few stars within ten light-years of the Sun. The closest is the triple star system Alpha Centauri, which is about 4.4 light-years away. Alpha Centauri A and B are a closely tied pair of Sun-like stars, whereas the small red dwarf, Proxima Centauri, orbits the pair at a distance of 0.2 light-year. In 2016, a potentially habitable exoplanet was confirmed to be orbiting Proxima Centauri, called Proxima Centauri b, the closest confirmed exoplanet to the Sun. The stars next closest to the Sun are the red dwarfs Barnard's Star (at 5.9 ly), Wolf 359 (7.8 ly), and Lalande 21185 (8.3 ly).

These particles are studied in chemistry, as well as atomic and molecular physics. The smallest of particles are the subatomic particles, which refer to particles smaller than atoms. These would include particles such as the constituents of atoms – protons, neutrons, and electrons – as well as other types of particles which can only be produced in particle accelerators or cosmic rays.

text: Traditionally, the defining characteristic for starhood has been an object's ability to fuse hydrogen in its core. However, stars such as brown dwarfs have always challenged that distinction. Too small to commence sustained hydrogen fusion, they have been granted star status on their ability to fuse deuterium. However, due to the relative rarity of that isotope, this process lasts only a tiny fraction of the star's lifetime, and hence most brown dwarfs would have ceased fusion long before their discovery. Binary stars and other multiple-star formations are common, and many brown dwarfs orbit other stars. Therefore, since they do not produce energy through fusion, they could be described as planets. Indeed, astronomer Adam Burrows of the University of Arizona claims that "from the theoretical perspective, however different their modes of formation, extrasolar giant planets and brown dwarfs are essentially the same." Burrows also claims that such stellar remnants as white dwarfs should not be considered stars, a stance which would mean that an orbiting white dwarf, such as Sirius B, could be considered a planet. However, the current convention among astronomers is that any object massive enough to have possessed the capability to sustain atomic fusion during its lifetime should be considered a star.

text: In some ancient atlases, the constellations Serpens and Ophiuchus were depicted as two separate constellations, although more often they were shown as a single constellation. One notable figure to depict Serpens separately was Johann Bayer; thus, Serpens' stars are cataloged with separate Bayer designations from those of Ophiuchus. When Eugène Delporte established modern constellation boundaries in the 1920s, he elected to depict the two separately. However, this posed the problem of how to disentangle the two constellations, with Deporte deciding to split Serpens into two areas—the head and the tail—separated by the continuous Ophiuchus. These two areas became known as Serpens Caput and Serpens Cauda, caput being the Latin word for head and cauda the Latin word for tail.

text: These results came at the beginning of the golden age of general relativity, which was marked by general relativity and black holes becoming mainstream subjects of research. This process was helped by the discovery of pulsars in 1967, which, by 1969, were shown to be rapidly rotating neutron stars. Until that time, neutron stars, like black holes, were regarded as just theoretical curiosities; but the discovery of pulsars showed their physical relevance and spurred a further interest in all types of compact objects that might be formed by gravitational collapse.

text: At the next stage, the envelope completely disappears, having been gathered up by the disk, and the protostar becomes a classical T Tauri star.  The latter have accretion disks and continue to accrete hot gas, which manifests itself by strong emission lines in their spectrum. The former do not possess accretion disks. Classical T Tauri stars evolve into weakly lined T Tauri stars. This happens after about 1 million years. The mass of the disk around a classical T Tauri star is about 1–3% of the stellar mass, and it is accreted at a rate of 10 to  per year. A pair of bipolar jets is usually present as well. The accretion explains all peculiar properties of classical T Tauri stars: strong flux in the emission lines (up to 100% of the intrinsic luminosity of the star), magnetic activity, photometric variability and jets. The emission lines actually form as the accreted gas hits the "surface" of the star, which happens around its magnetic poles. The jets are byproducts of accretion: they carry away excessive angular momentum. The classical T Tauri stage lasts about 10 million years.  The disk eventually disappears due to accretion onto the central star, planet formation, ejection by jets, and photoevaporation by ultraviolet radiation from the central star and nearby stars. As a result, the young star becomes a weakly lined T Tauri star, which, over hundreds of millions of years, evolves into an ordinary Sun-like star, dependent on its initial mass.

text: Around 25-33% of white dwarfs have metal lines in their spectra, which is unusual because any heavy elements in a white dwarf should sink into the star's interior in just a small fraction of the star's lifetime. The prevailing explanation for metal-rich white dwarfs is that they have recently accreted rocky planetesimals. The bulk composition of the accreted object can be measured from the strengths of the metal lines. For example, a 2015 study of the white dwarf Ton 345 concluded that its metal abundances were consistent with those of a differentiated, rocky planet whose mantle had been eroded by the host star's wind during its asymptotic giant branch phase.

text: The development begins with two main sequence stars in a binary relation. One of the two evolves into a red giant leaving its remnant white dwarf core in orbit with the remaining star. The second star—which may be either a main sequence star, or an aging giant one as well—begins to shed its envelope onto its white dwarf companion when it overflows its Roche lobe. As a result, the white dwarf will steadily accrete matter from the companion's outer atmosphere; the white dwarf consists of degenerate matter, so the accreted hydrogen does not inflate as its temperature increases. Rapid, uncontrolled fusion occurs when the temperature of this accreted layer reaches ~20 million Kelvins, initiating a burn via the CNO cycle.

text: The initial recordings were made at Rockfield Studios - "Snow Covered Eyes" and "Living In The World Today". The rest of the album was recorded in April 1974 at Chipping Norton Recording Studios.  Released in September 1974 Black Hole Star featured Neutrons' logo, designed by Rick Griffin, whilst the track "Mermaid And Chips" features the lyrics of Pete Brown.  The album spawned one single "Dance of the Psychedelic Lounge Lizard"/"Suzy and the Wonder Boy", The A-side being dedicated to Graham Bond, whilst the B side was not on the album, although it features Dave Edmunds on slide guitar.

text: In 1881 Pickering hired Fleming to join the HCO and taught her how to analyze stellar spectra; she was the first of an all-women cadre of human "computers"  created by Pickering at HCO. Soon she devised a system for classifying stars according to the relative amount of hydrogen observed in their spectra. (Stars showing hydrogen as the most abundant element were  classified A; those of hydrogen as the second-most abundant element, B; and so on.)  Later, Annie Jump Cannon developed an improved classification system based upon the surface temperature of stars.

text: Circumstellar habitable zones change over time with stellar evolution. For example, hot O-type stars, which may remain on the main sequence for fewer than 10 million years, would have rapidly changing habitable zones not conducive to the development of life. Red dwarf stars, on the other hand, which can live for hundreds of billions of years on the main sequence, would have planets with ample time for life to develop and evolve. Even while stars are on the main sequence, though, their energy output steadily increases, pushing their habitable zones farther out; our Sun, for example, was 75% as bright in the Archaean as it is now, and in the future, continued increases in energy output will put Earth outside the Sun's habitable zone, even before it reaches the red giant phase. In order to deal with this increase in luminosity, the concept of a continuously habitable zone has been introduced. As the name suggests, the continuously habitable zone is a region around a star in which planetary-mass bodies can sustain liquid water for a given period of time. Like the general circumstellar habitable zone, the continuously habitable zone of a star is divided into a conservative and extended region.

Its discovery made it the first multiplanetary system to be discovered around a main sequence star, and the first such system known in a multiple star system. The exoplanet was found by using the radial velocity method, where periodic Doppler shifts of spectral lines of the host star suggest an orbiting object.

text: A symbiotic star is a type of binary star. They are usually a white dwarf with a companion late sequence red giant. They are indicated by the exhibition of spectral lines of the highly contrasting temperatures of the red giant (~3000 K) and the white dwarf (~20 000 K). The white dwarf gains mass from stellar wind from the red giant or gravitational streaming.

text: In both the primary and secondary star, their cores will eventually collapse, resulting in a supernova explosion.  The initially-more massive primary will collapse first, probably as a type Ic supernova, within a few hundred thousand years.  The secondary will live on as a single star, or possibly in a binary with a supernova remnant, for a few million years before it also explodes as a supernova, probably a type Ib.  Massive stars at SMC metallicity may produce a low luminosity supernova, or even collapse directly to a black hole without a visible explosion.

text: Natural nuclear reactions occur in the interaction between cosmic rays and matter, and nuclear reactions can be employed artificially to obtain nuclear energy, at an adjustable rate, on demand. Perhaps the most notable nuclear reactions are the nuclear chain reactions in fissionable materials that produce induced nuclear fission, and the various nuclear fusion reactions of light elements that power the energy production of the Sun and stars. Both of these types of reactions are employed in nuclear weapons.

text: Hydrogen generally determines a star's nuclear lifetime because it is used as the main source of fuel in a main sequence star. Hydrogen becomes helium in the nuclear reaction that takes place within stars; when the hydrogen has been exhausted, the star moves on to another phase of its life and begins burning the helium.

text: Rigel A is a blue supergiant that has exhausted burning the hydrogen fuel in its core and left the main sequence, expanding and brightening as it progresses across the Hertzsprung–Russell diagram. Przybilla estimated that it has lost around 3 solar masses since beginning life as a star of 24 ± 3 solar masses 7 to 9 million years ago. It will become a red supergiant and eventually end its stellar life by exploding as a type II supernova, in the process flinging out material that will serve to seed future generations of stars. It is one of the closest known potential supernova progenitors to Earth.

text: The chemical composition of this star differs from that of other yellow supergiant stars. The star is moderately metal-deficient and the main elements present in the star (apart from hydrogen and helium) are oxygen, carbon and nitrogen. Molecules such as hydrogen isocyanide, sulfur monoxide and HCO have been detected in the circumstellar envelope of the star. These molecules may result from an active photochemistry, generated by UV photons emitted by the central star as it warms up, or can be produced in shocks.

text: In general, stars with lower metallicity are smaller and hotter than stars with higher metallicity.  For subgiants, this is complicated by different ages and core masses at the main sequence turnoff.  Low metallicity stars develop a larger helium core before leaving the main sequence, hence lower mass stars show a hook at the start of the subgiant branch.  The helium core mass of a Z=0.001 (extreme population II)  star at the end of the main sequence is nearly double that of a Z=0.02 (population I) star.  The low metallicity star is also over 1,000 K hotter and over twice as luminous at the start of the subgiant branch.  The difference in temperature is less pronounced at the end of the subgiant branch, but the low metallicity star is larger and nearly four times as luminous.  Similar differences exist in the evolution of stars with other masses, and key values such as the mass of a star that will become a supergiant instead of reaching the red giant branch are lower at low metallicity.

text: SN 1987A appears to be a core-collapse supernova, which should result in a neutron star given the size of the original star. The neutrino data indicate that a compact object did form at the star's core. However, since the supernova first became visible, astronomers have been searching for the collapsed core but have not detected it. The Hubble Space Telescope has taken images of the supernova regularly since August 1990, but, so far, the images have shown no evidence of a neutron star. A number of possibilities for the 'missing' neutron star are being considered, although none are clearly favored. The first is that the neutron star is enshrouded in dense dust clouds so that it cannot be seen. Another is that a pulsar was formed, but with either an unusually large or small magnetic field. It is also possible that large amounts of material fell back on the neutron star, so that it further collapsed into a black hole. Neutron stars and black holes often give off light when material falls onto them. If there is a compact object in the supernova remnant, but no material to fall onto it, it would be very dim and could therefore avoid detection. Other scenarios have also been considered, such as if the collapsed core became a quark star.

text: In the initial film, Solo brags that the Falcon made the Kessel Run in "less than twelve parsecs". As the parsec is a unit of distance, not time, different explanations have been provided. In the fourth draft of the script, Kenobi "reacts to Solo’s stupid attempt to impress them with obvious misinformation". In the Expanded Universe, the Kessel Run is a pathway from Kessel past the Maw Black Hole Cluster: used by smugglers to transport precious Glitterstim spice; and Solo's bragging refers to his ability to move the ship closer to the Maw's black holes and therefore shorten the distance traveled. On the Star Wars DVD audio commentary, Lucas comments that, in the Star Wars universe, traveling through hyperspace requires careful navigation to avoid stars, planets, asteroids, and other obstacles, and that because no long-distance journey can be made in a straight line, the "fastest" ship is the one that can plot the "most direct course", thereby traveling the least distance.However, since a parsec relates to a measurement of distance dependent on the motion of the observer and the angular shift in the position of a distant object, it would be unsuitable (to say the least) as a standard unit of distance for use by a galactic empire or in interstellar navigation, rendering any attempt to make the line have any scientifically accurate meaning futile.

text: Colgate's supernova research during this investigation ignited his interest in astrophysics. Colgate and Johnson's first attempts to understand the mechanism of a supernova began with determining the actual cause of one. They assumed that "a shockwave from the core bounce smashes into nuclear ash plummeting inwards due to the inward tug of gravity". The shock wave would turn this matter around, heating it up, causing the supernova. However this turned out to be wrong, as Richard H. White used computer simulations to show that the shock wave would not be strong enough to trigger the event. Colgate and White began developing models of stars on the verge of collapse. White wrote a computer program combining software used to design bombs with equations of state for a star. In discussions with a friend, Colgate found that neutrinos can develop degeneracy pressure. This pressure aided the shock wave in blowing off the outer shells of an expiring star, leaving a neutron star behind. While this research helped validate Chandrasekhar's work on limits, neutron stars were still purely hypothetical.

text: The progenitor of this white dwarf had an estimated 2.6 solar masses and remained on the main sequence for about . This gives the star a combined age of about 4.1 billion years. When this star left the main sequence, it expanded into a red giant that reached a maximum radius of 650 times the current radius of the Sun, or about 3 astronomical units. Any planets that were orbiting within this radius would have interacted directly with the star's extended envelope.

text: A star's metallicity measurement is one parameter that helps determine if a star will have planets and the type of planets, as there is a direct correlation between metallicity and the type of planets a star may have. Measurements have demonstrated the connection between a star's metallicity and gas giant planets, like Jupiter and Saturn.  The more metals in a star and thus its planetary system and proplyd, the more likely the system may have gas giant planets and rocky planets.  Current models show that the metallicity along with the correct planetary system temperature and distance from the star are key to planet and planetesimal formation. Metallicity also affects a star's color temperature.  Metal poor stars are bluer and metal rich stars are redder. The Sun, with 8 planets and 5 planetesimals, is used as the reference, with a [Fe/H] of 0.00. Other stars are noted with a positive or negative value.  A star with a  has the same iron abundance as the Sun. A star with  has one tenth heavy elements of that found in the Sun. At , the heavy element abundance is 10 times the Sun's value. The survey of stellar population of stars shows that older stars have less metallicity.

text: Draco is home to several double stars and binary stars. η Draconis is a double star with a yellow-hued primary of magnitude 2.8 and a white-hued secondary of magnitude 8.2 located south of the primary. The two are separated by 4.8 arcseconds. Mu Draconis, traditionally called Alrakis, is a binary star with two white components. Magnitude 5.6 and 5.7, the two components orbit each other every 670 years. The Alrakis system is 88 light-years from Earth. Nu Draconis is a similar binary star with two white components, 100 light-years from Earth. Both components are of magnitude 4.9 and can be distinguished in a small amateur telescope or a pair of binoculars. Omicron Draconis is a double star divisible in small telescopes. The primary is an orange giant of magnitude 4.6, 322 light-years from Earth. The secondary is of magnitude 7.8. Psi Draconis is a binary star divisible in binoculars and small amateur telescopes, 72 light-years from Earth. The primary is a yellow-white star of magnitude 4.6 and the secondary is a yellow star of magnitude 5.8. 16 Draconis and 17 Draconis are part of a triple star 400 light-years from Earth, divisible in medium-sized amateur telescopes. The primary, a blue-white star of magnitude 5.1, is itself a binary with components of magnitude 5.4 and 6.5. The secondary is of magnitude 5.5 and the system is 400 light-years away. 20 Draconis is a binary star with a white-hued primary of magnitude 7.1 and a yellow-hued secondary of magnitude 7.3 located east-northeast of the primary. The two are separated by 1.2 arcseconds at their maximum and have an orbital period of 420 years. As of 2012, the two components are approaching their maximum separation. 39 Draconis is a triple star 188 light-years from Earth, divisible in small amateur telescopes. The primary is a blue star of magnitude 5.0, the secondary is a yellow star of magnitude 7.4, and the tertiary is  a star of magnitude 8.0; the tertiary appears to be a close companion to the primary. 40 Draconis and 41 Draconis are a binary star divisible in small telescopes. The two orange dwarf stars are 170 light-years from Earth and are of magnitude 5.7 and 6.1.

text: The study of stars and stellar evolution is fundamental to our understanding of the Universe. The astrophysics of stars has been determined through observation and theoretical understanding; and from computer simulations of the interior. Star formation occurs in dense regions of dust and gas, known as giant molecular clouds. When destabilized, cloud fragments can collapse under the influence of gravity, to form a protostar. A sufficiently dense, and hot, core region will trigger nuclear fusion, thus creating a main-sequence star.

text: A mix of D-T at standard conditions does not undergo fusion; the nuclei must be forced together before the nuclear force can pull them together into stable collections. Even in the hot, dense center of the sun, the average proton will exist for billions of years before it fuses. For practical fusion power systems, the rate must be dramatically increased; heated to tens of millions of degrees, and/or compressed to immense pressures. The temperature and pressure required for any particular fuel to fuse is known as the Lawson criterion. These conditions have been known since the 1950s when the first H-bombs were built. To meet the Lawson Criterion is extremely difficult on Earth, which explains why fusion research has taken many years to reach the current high state of technical prowess.

text: During this phase of the contraction, the potential energy of gravitational contraction heats the interior to 5 GK (430 keV) and this opposes and delays the contraction. However, since no additional heat energy can be generated via new fusion reactions, the final unopposed contraction rapidly accelerates into a collapse lasting only a few seconds. The central portion of the star is now crushed into either a neutron star or, if the star is massive enough, a black hole. The outer layers of the star are blown off in an explosion known as a Type II supernova that lasts days to months. The supernova explosion releases a large burst of neutrons, which may synthesize in about one second roughly half of the supply of elements in the universe that are heavier than iron, via a rapid neutron-capture sequence known as the r-process (where the “r” stands for rapid neutron capture).

text: A particle accelerator is a machine that uses electromagnetic fields to propel charged particles to nearly light speed and to contain them in well-defined beams.Large accelerators are used in particle physics as colliders (e.g. the LHC at CERN, KEKB at KEK in Japan, RHIC at Brookhaven National Laboratory, and Tevatron at Fermilab), or as synchrotron light sources for the study of condensed matter physics. Smaller particle accelerators are used in a wide variety of applications, including particle therapy for oncological purposes, radioisotope production for medical diagnostics, ion implanters for manufacture of semiconductors, and accelerator mass spectrometers for measurements of rare isotopes such as radiocarbon.  There are currently more than 30,000 accelerators in operation around the world.

text: This star is roughly halfway through the initial phase of its stellar evolution and will, within the next few million years, expand into a red supergiant star wider than the orbit of Jupiter before ending its life in a supernova explosion leaving behind a neutron star or pulsar. From the Earth, a significant fraction of the light from this star is absorbed by interstellar dust, particularly at the blue end of the spectrum. In fact, were it not for this dust, ζ Ophiuchi would shine several times brighter and be among the very brightest stars visible.

text: After leaving NASA, Huntress continued to provide testimony to Congress regarding space funding and budgetary issues, including a series of congressional hearings in October 2003 on the future of NASA. In 2001 he testified before the House Subcommittee on Space and Aeronautics, setting forward four "grand challenges" for American space exploration. According to the Washington Times, those challenges were: "(1) To seek evidence of life elsewhere in the solar system where liquid water existed in the past or exists now. (2) To study planets around other stars (the sun being the star of our planetary system). (3) To send a spacecraft to a nearby star, something we don't know how to do today - "but in 1900 we didn't know how to fly either." (4) To develop a plan of human exploration beyond Earth orbit."

text: Within any giant luminosity class, the cooler stars (spectral class K, M, S, and C) are called red giants. Red giants include stars in a number of distinct evolutionary phases of their lives: a main red-giant branch (RGB); a red horizontal branch or red clump; the asymptotic giant branch (AGB), although AGB stars are often large enough and luminous enough to get classified as supergiants; and sometimes other large cool stars such as immediate post-AGB stars.  The RGB stars are by far the most common type of giant star due to their moderate mass, relatively long stable lives, and luminosity. They are the most obvious grouping of stars after the main sequence on most HR diagrams, although white dwarfs are more numerous but far less luminous.

text: All current thermonuclear weapons use a fission bomb as a first stage to create the high temperatures and pressures necessary to start a fusion reaction between deuterium and tritium in a second stage.  For many years, nuclear weapon designers have researched whether it is possible to create high enough temperatures and pressures inside a confined space to ignite a fusion reaction, without using fission. Pure fusion weapons offer the possibility of generating very small nuclear yields and the advantage of reduced collateral damage stemming from fallout because these weapons would not create the highly radioactive byproducts associated with fission-type weapons. These weapons would be lethal not only because of their explosive force, which could be large compared to bombs based on chemical explosives, but also because of the neutrons they generate.

text: WNh stars, spectroscopically similar but actually a much less evolved star which has only just started to expel its atmosphere, are an exception and still retain much of their initial mass.  The most massive stars currently known are all WNh stars rather than O-type main-sequence stars, an expected situation because such stars show helium and nitrogen at the surface only a few thousand years after they form, possibly before they become visible through the surrounding gas cloud.  An alternative explanation is that these stars are so massive that they could not form as normal main-sequence stars, instead being the result of mergers of less extreme stars.

text: Kepler-20 is a Sun-like star in the constellation Lyra with a mass of 0.91 (± 0.03)  and a radius of 0.94 (± 0.06) , and is thought to be 8.8 billion years old, though there is a large uncertainty in its age. In other words, Kepler-20 is approximately 9% less massive and 6% shorter than the Sun. The star's metallicity is 0.01 (± 0.04), meaning that the level of iron (and, presumably, other elements) in the star is almost the same as that of the Sun. Metallicity plays an important role in planetary systems, and stars with higher metallicity are more likely to have planets detected around them. This may be because the higher metallicity provides more material with which to quickly build planets into gas giants or because the higher metallicity increases planet migration towards the host star, making the planet easier to detect. The star has four other known planets in orbit: Kepler-20b, Kepler-20c, Kepler-20d, and Kepler-20e. All of the planets in the system would fit inside the orbit of Mercury.

text: The number of protons and neutrons in the atomic nucleus can be modified, although this can require very high energies because of the strong force. Nuclear fusion occurs when multiple atomic particles join to form a heavier nucleus, such as through the energetic collision of two nuclei. For example, at the core of the Sun protons require energies of 3–10 keV to overcome their mutual repulsion—the coulomb barrier—and fuse together into a single nucleus. Nuclear fission is the opposite process, causing a nucleus to split into two smaller nuclei—usually through radioactive decay. The nucleus can also be modified through bombardment by high energy subatomic particles or photons. If this modifies the number of protons in a nucleus, the atom changes to a different chemical element.

text: The Book of Abraham is unclear about Kolob being a star or a planet, and Mormon writings have taken positions on either side of this issue. One part of the Book of Abraham states that Abraham "saw the stars ... and that one of them was nearest unto the throne of God; ... and the name of the great one is Kolob." Thus, Kolob is referred to as a "star". However, the book defines the word "Kokaubeam" (a transliteration of the Hebrew "כּוֹכָבִים" [c.f., Gen. 15:5]) as meaning "all the great lights, which were in the firmament of heaven". This would appear to include planets as among the "stars", and the Book of Abraham refers to Earth as a star. In addition, the Book of Abraham text appears to classify Kolob as among a hierarchy of "planets". On the other hand, in the Egyptian Alphabet and Grammar paper, Kolob is classified as one of twelve "fixed stars", in distinction with fifteen "moving planets". The term "fixed star" generally refers to an astronomical object that does not seem to move across the sky, but may have a slow proper motion, as discovered in 1718 by Edmund Halley. Though "fixed", according to Smith, Kolob moves "swifter than the rest of the twelve fixed stars". Moreover, in the Book of Abraham, Smith refers to "fixed planets or stars", implying that some planets may be "fixed". He also refers to the Sun as a "governing planet", which further complicates the terminology. Therefore, there is no consensus on whether Smith understood Kolob to be a planet or a star as those terms are used in modern astronomy.

text: In 1595 Plancius asked Pieter Dirkszoon Keyser, the chief pilot on the Hollandia, to make observations to fill in the blank area around the south celestial pole on European maps of the southern sky. Keyser died in Java the following year – the expedition had many casualties – but his catalogue of 135 stars, probably measured up with the help of explorer-colleague Frederick de Houtman, was delivered to Plancius.  These stars appear as 12 new southern constellations, on a 35-cm celestial globe designed by Plancius in late 1597 (or early 1598) and produced in collaboration with the Amsterdam cartographer Jodocus Hondius the Elder. The 12 new constellations (mostly referring to animals and subjects described in natural history books and travellers' journals of his day) are Apis the Bee (later changed to Musca by Lacaille), Apus the Bird of Paradise, Chamaeleon, Dorado the Goldfish (or Swordfish), Grus the Crane, Hydrus the Small Water Snake, Indus the Indian, Pavo the Peacock, Phoenix, Triangulum Australe the Southern Triangle, Tucana the Toucan, and Volans the Flying Fish. (The Southern Triangle and Southern Cross were reported as asterisms by earlier navigators and appear on earlier charts, but the globe of 1598 is the first surviving source that plots their locations reasonably accurately.)  Also notable is the inclusion of Achernar as Alpha Eridani.

text: Stars more massive than about  cannot expand into a red supergiant.  They burn too quickly and lose their outer layers too quickly, so they reach the blue supergiant stage, or perhaps yellow hypergiant, and then return to become hotter stars.  The most massive stars, above about , hardly move at all from their position as O main-sequence stars.  These stars convect so efficiently that they mix hydrogen from the surface right down to the core.  They continue to fuse hydrogen until it is almost entirely depleted throughout the star, then very rapidly evolve through a series of stages of very similar hot and luminous stars, if supergiants, slash stars, WNh-, WN-, and possibly WC- or WO-type stars. They are expected to explode as supernovae, but it is not clear how far they evolve before this happens.  The existence of these supergiants still burning hydrogen in their cores may necessitate a slightly more complex definition of supergiant: a massive star with increased size and luminosity due to fusion products building up, but still with some hydrogen remaining.

text: The components of binary stars are denoted by the suffixes A and B appended to the system's designation, A denoting the primary and B the secondary. The suffix AB may be used to denote the pair (for example, the binary star α Centauri AB consists of the stars α Centauri A and α Centauri B.) Additional letters, such as C, D, etc., may be used for systems with more than two stars. In cases where the binary star has a Bayer designation and is widely separated, it is possible that the members of the pair will be designated with superscripts; an example is Zeta Reticuli, whose components are ζ Reticuli and ζ Reticuli.

text: There are several dimmer stars within the borders of Crux. Epsilon Crucis is an orange-hued giant star of magnitude 3.6, 228 light-years from Earth. Iota Crucis is a binary star 125 light-years from Earth. The primary is an orange-hued giant of magnitude 4.6 and the secondary is of magnitude 9.5. Mu Crucis is a double star where the unrelated components are about 370 light-years from Earth. The primary is a blue-white hued star of magnitude 4.0 and the secondary is a blue-white hued star of magnitude 5.1. Mu Crucis is divisible in small amateur telescopes or large binoculars.

text: The stellar classification of this star has undergone some revision over time, with the star being classified anywhere from an F-type main sequence star to a giant star. In 2006, the NStars program assigned it a class of F5 IV, where the luminosity class of 'IV' indicates this is a subgiant star that is exhausting the supply of hydrogen at its core and is in the process of evolving into a giant star. It has around 175% of the Sun's mass with an estimated age of 1.1 billion years. The star is radiating about 18 times the luminosity of the Sun from its outer atmosphere at an effective temperature of 6,519 K. It is this heat that gives it a yellow-white hue that is typical for an F-type star.

text: Algol (from the Arabic رأس الغول Ra's al-Ghul, which means The Demon's Head), also known by its Bayer designation Beta Persei, is the best-known star in Perseus. Representing the eye of the Gorgon Medusa in Greek mythology, it was called Horus in Egyptian mythology and Rosh ha Satan ("Satan's Head") in Hebrew. Located 92.8 light-years from Earth, it varies in apparent magnitude from a minimum of 3.5 to a maximum of 2.3 over a period of 2.867 days.The star system is the prototype of a group of eclipsing binary stars named Algol variables, though it has a third member to make up what is actually a triple star system. The brightest component is a blue-white main-sequence star of spectral type B8V, which is 3.5 times as massive and 180 times as luminous as the Sun. The secondary component is an orange subgiant star of type K0IV that has begun cooling and expanding to 3.5 times the radius of the Sun, and has 4.5 times the luminosity and 80% of its mass. These two are separated by only 0.05 astronomical units (AU)—five percent of the distance between the Earth and Sun; the main dip in brightness arises when the larger fainter companion passes in front of the hotter brighter primary. The tertiary component is a main sequence star of type A7, which is located on average 2.69 AU from the other two stars. AG Persei is another Algol variable in Perseus, whose primary component is a B-type main sequence star with an apparent magnitude of 6.69. Phi Persei is a double star, although the two components do not eclipse each other. The primary star is a Be star of spectral type B0.5, possibly a giant star, and the secondary companion is likely a stellar remnant. The secondary has a similar spectral type to O-type subdwarfs.

text: The revised Yerkes Atlas system (Johnson & Morgan 1953) listed a dense grid of F-type dwarf spectral standard stars; however, not all of these have survived to this day as standards.The anchor points of the MK spectral classification system among the F-type main-sequence dwarf stars, i.e. those standard stars that have remained unchanged over years and can be used to define the system, are considered to be 78 Ursae Majoris (F2 V) and pi3 Orionis (F6 V). In addition to those two standards, Morgan & Keenan (1973) considered the following stars to be dagger standards: HR 1279 (F3 V), HD 27524 (F5 V), HD 27808 (F8 V), HD 27383 (F9 V), and Beta Virginis (F9 V). Other primary MK standard stars include HD 23585 (F0 V), HD 26015 (F3 V), and HD 27534 (F5 V). Note that two Hyades members with almost identical HD names (HD 27524 and HD 27534) are both considered strong F5 V standard stars, and indeed they share nearly identical colors and magnitudes.Gray & Garrison (1989) provide a modern table of dwarf standards for the hotter F-type stars. F1 and F7 dwarf standards stars are rarely listed, but have changed slightly over the years among expert classifiers. Often-used standard stars include 37 Ursae Majoris (F1 V) and Iota Piscium (F7 V). No F4 V standard stars have been published. Unfortunately F9 V defines the boundary between the hot stars classified by Morgan, and the cooler stars classified by Keenan, and there are discrepancies in the literature on which stars define the F/G dwarf boundary. Morgan & Keenan (1973) listed Beta Virginis and HD 27383 as F9 V standards, but Keenan & McNeil (1989) listed HD 10647 as their F9 V standard. Eta Cassiopeiae A should probably be avoided as a standard star because it was often considered F9 V in Keenan's publications, but G0 V in Morgan's publications.

text: Star formation does not seem to be occurring currently at the Galactic Center, although the Circumnuclear Disk of molecular gas that orbits the Galactic Center at two parsecs seems a fairly favorable site for star formation. Work presented in 2002 by Antony Stark and Chris Martin mapping the gas density in a 400-light-year region around the Galactic Center has revealed an accumulating ring with a mass several million times that of the Sun and near the critical density for star formation. They predict that in approximately 200 million years there will be an episode of starburst in the Galactic Center, with many stars forming rapidly and undergoing supernovae at a hundred times the current rate. This starburst may also be accompanied by the formation of galactic jets as matter falls into the central black hole. It is thought that the Milky Way undergoes a starburst of this sort every 500 million years.

text: In physical cosmology, a protogalaxy, which could also be called a "primeval galaxy", is a cloud of gas which is forming into a galaxy. It is believed that the rate of star formation during this period of galactic evolution will determine whether a galaxy is a spiral or elliptical galaxy; a slower star formation tends to produce a spiral galaxy. The smaller clumps of gas in a protogalaxy form into stars.

text: A helium flash is a very brief thermal runaway nuclear fusion of large quantities of helium into carbon through the triple-alpha process in the core of low mass stars (between 0.8 solar masses () and 2.0 ) during their red giant phase (the Sun is predicted to experience a flash 1.2 billion years after it leaves the main sequence). A much rarer runaway helium fusion process can also occur on the surface of accreting white dwarf stars.

text: To determine if the expansion rate of the universe is speeding up or slowing down over time, cosmologists make use of the finite velocity of light. It takes billions of years for light from a distant galaxy to reach the Earth. Since the universe is expanding, the universe was smaller (galaxies were closer together) when light from distant galaxies was emitted. If the expansion rate of the universe is speeding up due to dark energy, then the size of the universe increases more rapidly with time than if the expansion were slowing down. Using supernovae, we cannot quite measure the size of the universe versus time. Instead we can measure the size of the universe (at the time the star exploded) and the distance to the supernova. With the distance to the exploding supernova in hand, astronomers can use the value of the speed of light along with the theory of General Relativity to determine how long it took the light to reach the Earth. This then tells them the age of the universe when the supernova exploded.

text: Stars greater than 8 solar masses (M) will likely end their lives in dramatic supernovae explosions, while planetary nebulae seemingly only occur at the end of the lives of intermediate and low mass stars between 0.8 M to 8.0 M. Progenitor stars that form planetary nebulae will spend most of their lifetimes converting their hydrogen into helium in the star's core by nuclear fusion at about 15 million K. This generated energy creates outward pressure from fusion reactions in the core, equally balancing the crushing inward pressures of the star's gravity. Hence, all single intermediate to low-mass stars on the main sequence can last for tens of millions to billions of years.

text: Working together with Kip Thorne in 1976, Żytkow developed a theoretical model for a new star type, the Thorne–Żytkow object (TŻO), which contains either a neutron star or a black hole core at the center of a stellar envelope. The evolution of such a star occurs rarely and only two processes exist that define the structure and evolution of a TŻO. In the first process a collision between a neutron star and a normal star, either dwarf or giant, must occur in order to merge the two into a single object. This occurrence is rare since stars do not usually collide with each other. This could only happen in a dense cluster of stars. The second possible evolution of a larger TŻO can occur when a  star expands into a red supergiant a and engulfs its companion neutron star.

text: The planet orbits a (M-type) red dwarf star named Gliese 667 C, orbited by a total of two planets. The star is part of a trinary star system, with Gliese 667 A and B both being more massive than the smaller companion. Gilese 667 C has a mass of 0.31  and a radius of 0.42 . It has a temperature of 3700 K, but its age is poorly constrained, estimates place it greater than 2 billion years old. In comparison, the Sun is 4.6 billion years old and has a surface temperature of 5778 K. This star is radiating only 1.4% of the Sun's luminosity from its outer atmosphere. It is known to have a system of two planets: claims have been made for up to seven, but these may be in error due to failure to account for correlated noise in the radial velocity data. Since red dwarfs emit little ultraviolet light, the planets likely receive minimal amounts of ultraviolet radiation.

text: As of August 27, 2007, discoveries concerning asymmetric iron line broadening and their implications for relativity have been a topic of much excitement. With respect to the asymmetric iron line broadening, Edward Cackett of the University of Michigan commented, "We're seeing the gas whipping around just outside the neutron star's surface,". "And since the inner part of the disk obviously can't orbit any closer than the neutron star's surface, these measurements give us a maximum size of the neutron star's diameter. The neutron stars can be no larger than 18 to 20.5 miles across, results that agree with other types of measurements."

text: In Orbient, players control a white star.  The game starts with the white star able to take 5 hits before it is destroyed.  To make it grow, the player must collide his/her star with a similar-sized, blue star.  Stars smaller than the player's star are gray-colored.  Colliding with these stars will not change the white star's size, but if the player positions the white star just right, the gray star will orbit the white and become a satellite.  Red stars are bigger than the white.  The white star is able to orbit red stars to help travel through space.  Whenever the white star grows large enough, the target star glows orange, and is able to be a satellite; as soon as that happens, a small crescent star appears, and having it successfully orbit the white star will give the player bonus points, (and collecting all different crescent stars unlocks new galaxies and are the goal to complete the game 100%).  Colliding with the orange star will take away a hit, but having it orbit the white star will clear the round. The player guides the star by pressing the A and B buttons on the Wii Remote to utilize gravity and anti-gravity, respectively, and attract it towards or repel against (also respectively) the gravitational wells of celestial objects.  Players must be careful not to crash their star into the red stars or floating objects like asteroids, or be sucked into black holes, which takes away a hit (and in the case of black holes, restart the entire stage).

text: Chattopadhyay completed his B.Sc. degree from Calcutta University in 1970, with Honors in Physics, graduating from St. Xavier’s College, a well known institution run by the early Jesuit clergy in India, which also boasts of having graduated the famous Indian scientist Prof. Jagadish Chandra Bose and Indian steel tycoon Laxmi Mittal. Caught in the turmoil of the politically vibrant and active university community in the city of Calcutta in the state of West Bengal in the late 1960s and early 1970s, he circumvented a delayed prospect of admission into the university’s post-graduate program by joining the Indian Institute of Technology at Kharagpur, eighty miles south-west of Calcutta, for his post-graduate studies, completing his M.Sc. degree with specialization in Particle Physics in 1972.Hoping to combine his passion for physics with the desire to explore nature, and upon direct invitation from Prof. Michael Moravscik as Chair of the Physics Interview Committee of the American Physical Society, he then joined in 1972 the Physics department of the University of Oregon at Eugene in the Pacific Northwest region of USA, known for its rugged natural beauty. However, over time, the draw towards the larger, diverse and vibrant campus of the University of California at Berkeley got stronger and with direct support and recommendation from Prof. Rudy Hwa and Prof. Berndt Crasemann while working on research projects with them in the summers of 1973 and 1974, he joined the University of California at Berkeley in 1974, as a Ph.D. student in the Department of Physics. After flirting for two years (1974-1976) with the inimitable Berkeley brand of theoretical particle physics, then known as the “S-matrix” and “Bootstrap” theories of “strong interactions”, under tutelage of Prof. Geoffrey Chew, Chattopadhyay was attracted away by the eclectic and pragmatic charm of accelerator physics dealing with charged particle and light beams under mentorship of some of the most prominent accelerator pioneers in the original accelerator laboratory created by Ernest Orlando Lawrence at Berkeley, such as: Edward J. Lofgren, Andrew Sessler, Denis Keefe, L. Jackson Laslett and Glen Lambertson, to name a few. In 1978, he was also heavily influenced by the visit of Simon van der Meer and Carlo Rubbia to the laboratory, speaking on the possibilities of stochastic phase space cooling of antiproton beams and the exciting possibilities with proton-antiproton collisions. He was also simultaneously being encouraged by Prof. Owen Chamberlain, discoverer of the ‘antiproton’ and a Berkeley Nobel laureate, to engage in antiproton beam research. He subsequently completed his PhD dissertation on the timely and critical topic of stochastic cooling of bunched beams of antiproton from the University of California (Berkeley) Physics department in 1982 and continued onto CERN as an “attaché scientifique” in the Super Proton Antiproton Synchrotron working with Daniel Boussard, Simon van der Meer and Carlo Rubbia, contributing to the ongoing program of stochastic cooling of antiproton beams, which led to the discovery of the W and Z vector bosons at CERN, and to the early ideas of stochastic cooling of “bunched” beams, which today are being applied successfully to phase space cooling of heavy ions at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory, leading to exciting new investigations of the ‘quark-gluon’ plasma in gold-on-gold collisions.

text: in 1972.Hoping to combine his passion for physics with the desire to explore nature, and upon direct invitation from Prof. Michael Moravscik as Chair of the Physics Interview Committee of the American Physical Society, he then joined in 1972 the Physics department of the University of Oregon at Eugene in the Pacific Northwest region of USA, known for its rugged natural beauty. However, over time, the draw towards the larger, diverse and vibrant campus of the University of California at Berkeley got stronger and with direct support and recommendation from Prof. Rudy Hwa and Prof. Berndt Crasemann while working on research projects with them in the summers of 1973 and 1974, he joined the University of California at Berkeley in 1974, as a Ph.D. student in the Department of Physics. After flirting for two years (1974-1976) with the inimitable Berkeley brand of theoretical particle physics, then known as the “

text: at Berkeley, such as:

text: Edward J. Lofgren

text: Andrew Sessler

text: , Denis Keefe, L. Jackson Laslett and Glen Lambertson, to name a few. In 1978, he was also heavily influenced by the visit of

text: beams and the exciting possibilities with proton-antiproton collisions. He was also simultaneously being encouraged by

text: Prof. Owen Chamberlain

text: , discoverer of the ‘antiproton’ and a Berkeley Nobel laureate, to engage in antiproton beam research. He subsequently completed his PhD dissertation on the timely and critical topic of stochastic cooling of bunched beams of antiproton from the University of California (Berkeley) Physics department in 1982 and continued onto CERN as an “attaché scientifique” in the Super Proton Antiproton Synchrotron working with Daniel Boussard, Simon van der Meer and Carlo Rubbia, contributing to the ongoing program of stochastic cooling of antiproton beams, which led to the discovery of the

text: This star has about 12% of the Sun's mass and 16% of the Sun's radius, but only 0.2% of the Sun's luminosity. It has a stellar classification of M6 V, which indicates it is a type of main sequence star known as a red dwarf. This is a flare star that occasionally increases in luminosity. With high probability there appears to be a long-term cycle of variability with a period of 4.20 years. This variability causes the star to range in visual magnitude from 12.23 to 12.34. In 1950, this became the first star to have a small variation in magnitude attributed to spots on its photosphere.

text: Depicting the eyepiece of the microscope is Gamma Microscopii, which—at magnitude of 4.68—is the brightest star in the constellation. Having spent much of its 620-million-year lifespan as a blue-white main sequence star, it has swollen and cooled to become a yellow giant of spectral type G6III, with a diameter ten times that of the Sun. Measurement of its parallax yields a distance of 229±4 light years from Earth. Alpha Microscopii is also an ageing yellow giant star of spectral type G7III with an apparent magnitude of 4.90. Located 380±30 light-years away from Earth, it has swollen to 17.5 times the diameter of the Sun. Alpha has a 10th magnitude companion, visible in 7.5 cm telescopes, though this is a coincidental closeness rather than a true binary system. Epsilon Microscopii lies 182±2 light years away, and is a white star of apparent magnitude 4.7, and spectral type A1V. Theta and Theta Microscopii make up a wide double whose components are splittable to the naked eye. Both are white A-class magnetic spectrum variable stars with strong metallic lines, similar to Cor Caroli. They mark the constellation's specimen slide.

text: Zeta Persei is the third-brightest star in the constellation at magnitude 2.86. Around 750 light-years from Earth, it is a blue-white supergiant 26–27 times the radius of the Sun and 47,000 times its luminosity. It is the brightest star (as seen from Earth) of a moving group of bright blue-white giant and supergiant stars, the Perseus OB2 Association or Zeta Persei Association. Zeta is a triple star system, with a companion blue-white main sequence star of spectral type B8 and apparent magnitude 9.16 around 3900 AU distant from the primary, and a white main sequence star of magnitude 9.90 and spectral type A2, some 50,000 AU away, that may or may not be gravitationally bound to the other two. X Persei is a double system in this association; one component is a hot, bright star and the other is a neutron star. With an apparent magnitude of 6.72, it is too dim to be seen with the naked eye even in perfectly dark conditions. The system is an X-ray source and the primary star appears to be undergoing substantial mass loss. Once thought to be a member of the Perseus OB2 Association, Omicron Persei is a multiple star system with a combined visual magnitude of 3.85. It is composed of two blue-white starsa giant of spectral class B1.5 and main sequence star of B3which orbit each other every 4.5 days and are distorted into ovoids due to their small separation. The system has a third star about which little is known. At an estimated distance of 1475 light-years from Earth, the system is now thought to lie too far from the center of the Zeta Persei group to belong to it.

text: Stars more massive than  spend a few million years on the main sequence as class O and early B stars until the hydrogen in their cores becomes depleted.  Then they expand and cool to become supergiants.  They spend only a few thousand years as a yellow supergiant while cooling to become a red supergiant, then one to four million years as a red supergiant.  Such massive stars make up less than 1% of all stars.  Combined with the relative lifetime of the yellow supergiant phase, this explains the rarity of these stars.

text: Paramount originally began work on a Star Trek feature film in 1975 after lobbying by the creator of the franchise, Gene Roddenberry. The studio scrapped the project two years later in favor of creating a television series, Star Trek: Phase II, with the original cast. However, following the huge success of Star Wars and Close Encounters of the Third Kind, Paramount changed its mind again, halting production on the television series and adapting its pilot episode into the Star Trek feature film, Star Trek: The Motion Picture (1979). Five more films featuring the entire original cast followed. The cast of the 1987–1994 spin-off series Star Trek: The Next Generation starred in a further four films. After a 6-year hiatus following the release of Star Trek: Nemesis (2002), a new film was released on May 16, 2009, simply titled Star Trek, serving as a reboot to the franchise with a new cast portraying younger versions of the original series' characters. A sequel to Star Trek (2009), Star Trek Into Darkness, was released in theaters on May 16, 2013. A second sequel, Star Trek Beyond, was released on July 22, 2016, on the franchise's 50th anniversary.

text: If the star's mass, when on the main sequence, was below approximately , it will never reach the central temperatures necessary to fuse helium.  It will therefore remain a hydrogen-fusing red giant until it runs out of hydrogen, at which point it will become a helium white dwarf. This is entirely theoretical because no star of such low mass has been in existence long enough to evolve to that stage.

text: After a star has formed, it generates thermal energy in the dense core region through nuclear fusion of hydrogen atoms into helium. During this stage of the star's lifetime, it is located along the main sequence at a position determined primarily by its mass, but also based upon its chemical composition and other factors. All main-sequence stars are in hydrostatic equilibrium, where outward thermal pressure from the hot core is balanced by the inward pressure of gravitational collapse from the overlying layers. The strong dependence of the rate of energy generation in the core on the temperature and pressure helps to sustain this balance. Energy generated at the core makes its way to the surface and is radiated away at the photosphere. The energy is carried by either radiation or convection, with the latter occurring in regions with steeper temperature gradients, higher opacity or both.

text: In the first phase (early 2017), the array will consist of 3 telescopes of 2.7 square degrees field of view each, later to be extended to more units with a total field of view of 40 square degrees. This also makes the BlackGEM array a very good survey instrument. The first phase of operations will therefore perform a complete survey of the southern sky. In parallel to this phase, multi-epoch imaging will give a characterization of any fast (shorter than one day) transient sources down to 23rd magnitude. In parallel, the BlackGEM array will act on triggers from the gravitational wave detectors to look for optical emission from such events as merging black holes and neutron stars.

text: Other names for Betelgeuse included the Persian Bašn "the Arm", and Coptic Klaria "an Armlet". Bahu was its Sanskrit name, as part of a Hindu understanding of the constellation as a running antelope or stag. In traditional Chinese astronomy, Betelgeuse was known as 参宿四 (Shēnxiùsì, the Fourth Star of the constellation of Three Stars) as the Chinese constellation 参宿 originally referred to the three stars in the girdle of Orion. This constellation was ultimately expanded to ten stars, but the earlier name stuck. In Japan, the Taira or Heike clan adopted Betelgeuse and its red color as its symbol, calling the star Heike-boshi, (平家星), while the Minamoto or Genji clan had chosen  Rigel and its white color. The two powerful families fought a legendary war in Japanese history, the stars seen as facing each other off and only kept apart by the Belt.

text: Astronomer Anatoly Miroshnichenko has made it the prototype of a new type of variable star, FS Canis Majoris stars. These are hot blue-white stars that exhibit forbidden line emission and strong infra-red excess suggestive of very young (pre-main-sequence) stars yet they do not lie in star-forming regions. Nor did they appear to be stars that had evolved off the main sequence into giant or supergiant stars. It is now thought that they are main sequence stars that have absorbed or are absorbing matter, most likely from a companion star, and are surrounded by a compact dusty shell. These stars are thought to be significant contributors to interstellar dust.

text: Most compact stars are the endpoints of stellar evolution and are thus often referred to as stellar remnants, the form of the remnant depending primarily on the mass of the star when it formed. These objects are all small in volume for their mass, giving them a very high density. The term compact star is often used when the exact nature of the star is not known, but evidence suggests that it is very massive and has a small radius, thus implying one of the above-mentioned categories. A compact star that is not a black hole may be called a degenerate star.

text: These stars, known as neutron stars, are extremely small—on the order of radius 10 km, no bigger than the size of a large city—and are phenomenally dense. Their period of rotation shortens dramatically as the stars shrink (due to conservation of angular momentum); observed rotational periods of neutron stars range from about 1.5 milliseconds (over 600 revolutions per second) to several seconds. When these rapidly rotating stars' magnetic poles are aligned with the Earth, we detect a pulse of radiation each revolution. Such neutron stars are called pulsars, and were the first neutron stars to be discovered. Though electromagnetic radiation detected from pulsars is most often in the form of radio waves, pulsars have also been detected at visible, X-ray, and gamma ray wavelengths.

text: Protostars with masses less than roughly  never reach temperatures high enough for nuclear fusion of hydrogen to begin. These are known as brown dwarfs. The International Astronomical Union defines brown dwarfs as stars massive enough to fuse deuterium at some point in their lives (13 Jupiter masses (), 2.5 × 10 kg, or ). Objects smaller than  are classified as sub-brown dwarfs (but if they orbit around another stellar object they are classified as planets). Both types, deuterium-burning and not, shine dimly and die away slowly, cooling gradually over hundreds of millions of years.

text: In 1984, a Type II-L supernova was discovered in this galaxy. Designated 1984E, the spectrum of this event at maximum light showed prominent balmer lines that indicated the explosion occurred inside a dense shell of hydrogen surrounding the star. This shell was likely created by a strong stellar wind from the progenitor star. A second supernova was discovered in 2003; this time of type 1a. It was designated SN 2003 cg and reached peak magnitude 15.94.

text: A nanoFET works in a fairly straight forward manner. It consists of 3 main parts: a particle storage area, a charging pad, and an acceleration grid. To start, it transports  cylindrical particles to the charging pad which then imposes a charge on the particles. As the particle gains charge, the pulling force from the acceleration grid increases. Eventually, this pulling force overpowers the electro-magnetic and surface adhesion forces between the particles and charging pad. Now the particle begins accelerating towards the acceleration grid until it is shot out of the nanoFET, consequently pushing the nanoFET in the opposite direction.

text: Stars with mass less than the Sun's mass, have very long lifetimes, long enough to be discovered. The distinctive chemical patterns of these low mass stars can be used to estimate the mass of the first generation stars.In the past thirty years astronomers have conducted large-scale investigations to find low-mass and metal-poor stars formed in the early Universe. The Sloan Digital Sky Survey (SDSS) and Sloan Extension for Galactic Understanding and Exploration (SEGUE) projects are the latest to obtain evidence for the age, chemical composition and distribution of stars in the Milky Way, and provided crucial clues to understand the structure, formation and evolution of the Milky Way Galaxy.

text: Although white dwarfs are known with estimated masses as low as 0.17  and as high as 1.33 , the mass distribution is strongly peaked at 0.6 , and the majority lie between 0.5 and 0.7 . The estimated radii of observed white dwarfs are typically 0.8–2 % the radius of the Sun; this is comparable to the Earth's radius of approximately 0.9% solar radius. A white dwarf, then, packs mass comparable to the Sun's into a volume that is typically a million times smaller than the Sun's; the average density of matter in a white dwarf must therefore be, very roughly, 1,000,000 times greater than the average density of the Sun, or approximately 10 g/cm, or 1 tonne per cubic centimetre. A typical white dwarf has a density of between 10 and 10 g/cm^3. White dwarfs are composed of one of the densest forms of matter known, surpassed only by other compact stars such as neutron stars, black holes and, hypothetically, quark stars.

text: PMS stars can be differentiated empirically from main-sequence stars by using stellar spectra to measure their surface gravity.  A PMS object has a larger radius than a main-sequence star with the same stellar mass and thus has a lower surface gravity. Although they are optically visible, PMS objects are rare relative to those on the main sequence, because their contraction lasts for only 1 percent of the time required for hydrogen fusion. During the early portion of the PMS stage, most stars have circumstellar disks, which are the sites of planet formation.

The 28 Chinese constellations, Xiu (), are quite different from Western constellations.  For example, the Big Bear (Ursa Major) is known as Dou (); the belt of Orion is known as Shen (), or the "Happiness, Fortune, Longevity" trio of demigods. The seven northern constellations are referred to as Xuan Wu ().  Xuan Wu is also known as the spirit of the northern sky or the spirit of Water in Taoism belief.

text: Deneb spent much of its early life as a  O-type main-sequence star but it has now exhausted the supply of hydrogen in its core and begun to cool and expand.  Stars in the mass range of Deneb eventually expand to become the most luminous red supergiants, and within a few million years their cores will collapse producing a supernova explosion.  It is now known that red supergiants up to a certain mass explode as the commonly seen type II-P supernovae, but more massive ones lose their outer layers to become hotter again.  Depending on their initial masses and the rate of mass loss, they may explode as yellow hypergiants or luminous blue variables, or they may become Wolf-Rayet stars before exploding in a type Ib or Ic supernova.  Identifying whether Deneb is currently evolving towards a red supergiant or is currently evolving bluewards again would place valuable constraints on the classes of stars that explode as red supergiants and those that explode as hotter stars.

text: In the mid-nineties, Bussard publications prompted the development of a fusors at the University of Wisconsin–Madison and at the University of Illinois at Urbana–Champaign.  Madison's machine was first built in 1995 and the group still produces some of the best IEC research in the world. Dr George H. Miley team at Illinois, built a 25 cm fusor which has produced 10 neutrons using deuterium gas  and discovered the "star mode" of fusor operation in 1994.  The following year, the first "US-Japan Workshop on IEC Fusion", was conducted. This is now the premier conference for IEC researchers.  At this time in Europe, an IEC device was developed as a commercial neutron source by Daimler-Chrysler Aerospace under the name FusionStar.  In the late nineties, hobbyist Richard Hull began building the first amateur fusors in his home in Virginia. In March 1999, he achieved a neutron rate of 10 neutrons per second. Hull and Paul Schatzkin, started fusor.net in 1998.  Through this open forum, a community of amateur fusioneers have done nuclear fusion using homemade fusors.

text: Two star systems have had exoplanets discovered by doppler spectroscopy, and the substellar companion of a third star system—the sunlike star HD 131664—has turned out to be a brown dwarf with a predicted mass of the companion to 23 times that of Jupiter (minimum of 18 and maximum of 49 Jovian masses). HD 134606 is a yellow sunlike star of spectral type G6IV that has begun expanding and cooling off the main sequence. Three planets orbit it with periods of 12, 59.5 and 459 days, successively larger as they are further away from the star. HD 137388 is another star—of spectral type K2IV—that is cooler than the Sun and has begun cooling off the main sequence. Around 47% as luminous and 88% as massive as the Sun, with 85% of its diameter, it is thought to be around 7.4 ± 3.9 billion years old. It has a planet that is 79 times as massive as the Earth and orbits its sun every 330 days at an average distance of 0.89 astronomical units (AU).

text: In this spacetime, it is possible to come up with coordinate systems such that if you pick a hypersurface of constant time (a set of points that all have the same time coordinate, such that every point on the surface has a space-like separation, giving what is called a 'space-like surface') and draw an "embedding diagram" depicting the curvature of space at that time, the embedding diagram will look like a tube connecting the two exterior regions, known as an "Einstein–Rosen bridge". Note that the Schwarzschild metric describes an idealized black hole that exists eternally from the perspective of external observers; a more realistic black hole that forms at some particular time from a collapsing star would require a different metric. When the infalling stellar matter is added to a diagram of a black hole's history, it removes the part of the diagram corresponding to the white hole interior region, along with the part of the diagram corresponding to the other universe.

text: While the position, velocity and acceleration of a particle can be described with respect to any observer in any state of motion, classical mechanics assumes the existence of a special family of reference frames in terms of which the mechanical laws of nature take a comparatively simple form. These special reference frames are called inertial frames. An inertial frame is one that when an object that has no force interactions (an idealized situation) is viewed from that frame, it appears either to be at rest or in a state of uniform motion in a straight line. This is the fundamental definition of an inertial frame. They are characterized by the requirement that all forces entering the observer's physical laws originate from identifiable sources caused by fields, such as electro-static field (caused by static electrical charges), electro-magnetic field (caused by moving charges), gravitational field (caused by mass), and so forth. A non-inertial reference frame is one that is accelerating with respect to an inertial frame, and in such a non-inertial frame a particle appears to be acted on by other forces not explained by existing fields. Such other forces are called variously fictitious forces, inertia forces, pseudo-forces. Hence, there appears to be other forces that enter the equations of motion solely as a result of the observed accelerations. A key concept of inertial frames is the method for identifying them. For practical purposes, reference frames that are unaccelerated with respect to the distant stars (an extremely distant point) are regarded as good approximations to inertial frames.

text: Five star systems have been found to have planets, four of which have been discovered by the High Accuracy Radial Velocity Planet Searcher (HARPS) in Chile. HD 4308 is a star with around 83% of the Sun's mass located 72 light-years away with a super-Earth planet with an orbital period of around 15 days. HD 215497 is an orange star of spectral type K3V around 142 light-years distant. It is orbited by a hot super-Earth every 3 days and a second planet around the size of Saturn with a period of around 567 days. HD 221287 has a spectral type of F7V and lies 173 light-years away, and has a super-Jovian planet. HD 7199 has spectral type KOIV/V and is located 117 light-years away. It has a planet with around 30% the mass of Jupiter that has an orbital period of 615 days. HD 219077 has a planet around 10 times as massive as Jupiter in a highly eccentric orbit.

text: Zeta Coronae Borealis is a double star with two blue-white components 6.3 arcseconds apart that can be readily separated at 100x magnification. The primary is of magnitude 5.1 and the secondary is of magnitude 6.0. Nu Coronae Borealis is an optical double, whose components are a similar distance from Earth but have different radial velocities, hence are assumed to be unrelated. The primary, Nu Coronae Borealis, is a red giant of spectral type M2III and magnitude 5.2, lying 640±30 light-years distant, and the secondary, Nu Coronae Borealis, is an orange-hued giant star of spectral type K5III and magnitude 5.4, estimated to be 590±30 light-years away. Sigma Coronae Borealis, on the other hand, is a true multiple star system divisible by small amateur telescopes. It is actually a complex system composed of two stars around as massive as the Sun that orbit each other every 1.14 days, orbited by a third Sun-like star every 726 years. The fourth and fifth components are a binary red dwarf system that is 14,000 AU distant from the other three stars. ADS 9731 is an even rarer multiple system in the constellation, composed of six stars, two of which are spectroscopic binaries.

It is a symbiotic star system composed of an orange giant of spectral type K2III and white dwarf in close orbit, with the smaller star ionizing the stellar wind of the larger star. The system is metal-poor. Combined with its high galactic latitude, this indicates that the star system has its origin in the galactic halo of the Milky Way.

text: Although most supergiant stars are less luminous than hypergiants of the same temperature, a few fall in the same luminosity range.  Ordinary supergiants lack the strong H emission and broadened spectral lines that indicate rapid mass loss in the hypergiants.  Lower mass supergiants do not return from the red supergiant phase, either exploding as supernovae or leaving behind a white dwarf.

text: Constellation cards represent star constellations in the sky which impact play in some way.  For example, a given Constellation might confer an additional power to the Neopets in play, or otherwise might change the game in some fashion. Wizards of the Coast has not given any official ruling as to the rules regarding constellations, but popular rule sets online (most notably in player-created "guilds" on the Neopets web site) considered them similar to Magic's enchantments.

text: Nuclear engineering is the branch of engineering concerned with the application of the breakdown (fission) as well as the fusion of atomic nuclei and/or the application of other sub-atomic physics, based on the principles of nuclear physics. In the sub-field of nuclear fission, it particularly includes the interaction and maintenance of systems and components like nuclear reactors, nuclear power plants, and/or nuclear weapons. The field also includes the study of medical and other applications of (generally ionizing) radiation, nuclear safety, heat/thermodynamics transport, nuclear fuel and/or other related technology (e.g., radioactive waste disposal), and the problems of nuclear proliferation.

text: Supergiants have masses from 8 to 12 times the Sun () upwards, and luminosities from about 1,000 to over a million times the Sun (). They vary greatly in radius, usually from 30 to 500, or even in excess of 1,000 solar radii (). They are massive enough to begin core helium burning gently before the core becomes degenerate, without a flash, and without the strong dredge-ups that lower-mass stars experience. They go on to successively ignite heavier elements, usually all the way to iron. Also because of their high masses they are destined to explode as supernovae.

This matches the expected parameters of lower mass red supergiants.  A small number of progenitors of type II-L and type IIb supernovae have been observed, all having luminosities around  and somewhat higher temperatures up to 6,000K.  These are a good match for slightly higher mass red supergiants with high mass loss rates.  There are no known supernova progenitors corresponding to the most luminous red supergiants, and it is expected that these evolve to Wolf Rayet stars before exploding.

text: The progenitor of SN 1993J was identified in pre-explosion ground-based images. The progenitor was observed to be a K-supergiant star, with an excess in the ultraviolet possibly due to surrounding hot stars or a hot binary companion.  While the supernova is located in a region populated by young massive stars, late-time photometry with the Hubble Space Telescope and spectroscopy with the Keck 10m-telescope presented by Maund and collaborators revealed the presence of the long suspected B-supergiant companion star.

text: Hydrogen fusion (nuclear fusion of four protons to form a helium-4 nucleus) is the dominant process that generates energy in the cores of main-sequence stars. It is also called "hydrogen burning", which should not be confused with the chemical combustion of hydrogen in an oxidizing atmosphere. There are two predominant processes by which stellar hydrogen fusion occurs: proton-proton chain and the carbon-nitrogen-oxygen (CNO) cycle. Ninety percent of all stars, with the exception of white dwarfs, are fusing hydrogen by these two processes.

text: It has been proposed that white dwarfs with surface temperatures of less than 10,000 kelvins could harbor a habitable zone at a distance between ~0.005 to 0.02 AU that would last upwards of 3 billion years. The goal is to search for transits of hypothetical Earth-like planets that could have migrated inward and/or formed there. As a white dwarf has a size similar to that of a planet, these kinds of transits would produce strong eclipses. Newer research casts some doubts on this idea, given that the close orbits of those hypothetical planets around their parent stars would subject them to strong tidal forces that could render them unhabitable by triggering a greenhouse effect. Another suggested constraint to this idea is the origin of those planets. Leaving aside in-situ formation on an accretion disk surrounding the white dwarf, there are two ways a planet could end in a close orbit around stars of this kind: by surviving being engulfed by the star during its red giant phase, and then spiraling towards its core, or inward migration after the white dwarf has formed. The former case is implausible for low-mass bodies, as they are unlikely to survive being absorbed by their stars. In the latter case, the planets would have to expel so much orbital energy as heat, through tidal interactions with the white dwarf, that they would likely end as uninhabitable embers.

text: The ISR (standing for "Intersecting Storage Rings") was a particle accelerator at CERN.  It was the world's first hadron collider, and ran from 1971 to 1984, with a maximum center of mass energy of 62 GeV.  From its initial startup, the collider itself had the capability to produce particles like the J/ψ and the upsilon, as well as observable jet structure; however, the particle detector experiments were not configured to observe events with large momentum transverse to the beamline, leaving these discoveries to be made at other experiments in the mid-1970s.  Nevertheless, the construction of the ISR involved many advances in accelerator physics, including the first use of stochastic cooling, and it held the record for luminosity at a hadron collider until surpassed by the Tevatron in 2004.

text: Of all the strands of his work, Velikovsky published least on his belief that electromagnetism plays a role in orbital mechanics. Although he appears to have retreated from the propositions in his 1946 monograph Cosmos without Gravitation, no such retreat is apparent in Stargazers and Gravediggers. Cosmos without Gravitation, which Velikovsky placed in university libraries and sent to scientists, is a probable catalyst for the hostile response of astronomers and physicists to his later claims about astronomy.  However, other Velikovskian enthusiasts such as Ralph Juergens (dec.), Earl Milton (dec.), Wal Thornhill, and Donald E. Scott have claimed that stars are powered not by internal nuclear fusion, but by galactic-scale electrical discharge currents. Such ideas do not find support in the conventional literature and are rejected as pseudoscience by the scientific community.

text: For at least a portion of its life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses the star's interior and then radiates into outer space. Almost all naturally occurring elements heavier than helium are created by stellar nucleosynthesis during the star's lifetime, and for some stars by supernova nucleosynthesis when it explodes. Near the end of its life, a star can also contain degenerate matter. Astronomers can determine the mass, age, metallicity (chemical composition), and many other properties of a star by observing its motion through space, its luminosity, and spectrum respectively. The total mass of a star is the main factor that determines its evolution and eventual fate. Other characteristics of a star, including diameter and temperature, change over its life, while the star's environment affects its rotation and movement. A plot of the temperature of many stars against their luminosities produces a plot known as a Hertzsprung–Russell diagram (H–R diagram). Plotting a particular star on that diagram allows the age and evolutionary state of that star to be determined.

text: A Polar (also AM Herculis Star) is a highly magnetic type of cataclysmic variable binary star system. Like other cataclysmic variables (CVs), polars contain two stars: an accreting white dwarf (WD), and a low-mass donor star (usually a red dwarf) which is transferring mass to the WD as a result of the WD's gravitational pull. (In technical terms, the donor star overfills its Roche lobe.) Polars are distinguished from other CVs by the presence of a very strong magnetic field in the WD. Typical magnetic field strengths of polar systems are 10 million to 80 million gauss (1000–8000 teslas). The WD in the polar AN Ursae Majoris has the strongest known magnetic field among cataclysmic variables, with a field strength of 230 million gauss (23 kT). The presence of such a strong magnetic field gives rise to a number of fundamental differences between polars and non-magnetic CVs.

text: For most ships, travel between star systems is only possible by using structures called "Stargates".

While travel within a star system by warp drive is relatively free-form, the need to use stargates to travel between systems makes them focal points for combat.

text: Fusion reactions occur when two (or more) atomic nuclei come close enough for long enough that the strong nuclear force pulling them together exceeds the electrostatic force pushing them apart, fusing them into heavier nuclei. For nuclei lighter than iron-56, the reaction is exothermic, releasing energy. For nuclei heavier than iron-56, the reaction is endothermic, requiring an external source of energy. Hence, nuclei smaller than iron-56 are more likely to fuse while those heavier than iron-56 are more likely to break apart.

text: After its cancellation, Star Trek engendered a cult following during the 1970s from syndicated reruns, and Captain Kirk became a cultural icon. Shatner began appearing at Star Trek conventions organized by Trekkies. In the mid-1970s, Paramount began pre-production for a revised Star Trek television series, tentatively titled Star Trek: Phase II. However, the phenomenal success of Star Wars (1977) led the studio to instead consider developing a Star Trek motion picture. Shatner and the other original Star Trek cast members returned to their roles when Paramount produced Star Trek: The Motion Picture, released in 1979. He played Kirk in the next six Star Trek films, ending with the character's death in Star Trek Generations (1994). Some later appearances in the role are in the movie sequences of the video game Starfleet Academy (1997), briefly for a DirecTV advertisement using footage from Star Trek VI: The Undiscovered Country running from late summer 2006, and the 2013 Academy Awards, in which he reprised the role for a comedic interlude with host Seth MacFarlane.

text: Black holes give off radiation because matter falling into them loses gravitational energy which may result in the emission of radiation before the matter falls into the event horizon. The infalling matter has angular momentum, which means that the material cannot fall in directly, but spins around the black hole. This material often forms an accretion disk. Similar luminous accretion disks can also form around white dwarfs and neutron stars, but in these the infalling gas releases additional energy as it slams against the high-density surface with high speed. In case of a neutron star, the infall speed can be a sizeable fraction of the speed of light.

An optical illusion causes things close to the red star to appear slightly greenish.The classical example is Antares B, the blue companion of the red supergiant  Antares, and another example is the star system Almach.

text: The non-classical kinds of carbon stars, belonging to the types C-J and C-H, are believed to be binary stars, where one star is observed to be a giant star (or occasionally a red dwarf) and the other a white dwarf. The star presently observed to be a giant star accreted carbon-rich material when it was still a main-sequence star from its companion (that is, the star that is now the white dwarf) when the latter was still a classical carbon star. That phase of stellar evolution is relatively brief, and most such stars ultimately end up as white dwarfs. We are now seeing these systems a comparatively long time after the mass transfer event, so the extra carbon observed in the present red giant was not produced within that star. This scenario is also accepted as the origin of the barium stars, which are also characterized as having strong spectral features of carbon molecules and of barium (an s-process element). Sometimes the stars whose excess carbon came from this mass transfer are called "extrinsic" carbon stars to distinguish them from the "intrinsic" AGB stars which produce the carbon internally. Many of these extrinsic carbon stars are not luminous or cool enough to have made their own carbon, which was a puzzle until their binary nature was discovered.

text: The bat'leth appeared in 29 television episodes across the Star Trek franchise in Star Trek: The Next Generation, Star Trek: Voyager, Star Trek: Deep Space Nine and Star Trek: Enterprise. The Bat'leth was also used in the 1994 film Star Trek Generations.  The mek'leth appeared in the television series Deep Space Nine and in the 1996 film Star Trek: First Contact. The Sword of Kahless appeared in the 2000 video game Star Trek: Armada and normal bat'leths appeared in the 1996 video game Star Trek: Klingon.  Some of the bat'leth's uses were in the debut episode "Reunion", where Worf teaches his son Alexander how to use one. Worf used a bat'leth to kill Durasa Klingon who killed Worf's mate K'Ehleyr. Notable uses of the weapon occurred in the Voyager episode "Barge of the Dead"in which Tuvok uses a bat'leth to teach B'Elanna Torres about her Klingon heritage, and in the Deep Space Nine episode "Tacking into the Wind" in which Worf kills the leader of the Klingon High Council, Gowron in a bat'leth duel to give the Klingon Chancellorship to General Martok.

text: Xi Telescopii is an irregular variable star that ranges between magnitudes 4.89 and 4.94. Located 1079 light-years distant, it is a red giant of spectral type M2III that has a diameter around 5.6 times the Sun's, and a luminosity around 2973 times that of the Sun. Another irregular variable, RX Telescopii is a red supergiant that varies between magnitudes 6.45 and 7.47, just visible to the unaided eye under good viewing conditions. BL Telescopii is an Algol-like eclipsing binary system that varies between apparent magnitudes 7.09 and 9.08 over a period of just over 778 days (2 years 48 days). The primary is a yellow supergiant that is itself intrinsically variable. Dipping from its baseline magnitude of 9.6 to 16.5, RS Telescopii is a rare R Coronae Borealis variable—an extremely hydrogen-deficient supergiant thought to have arisen as the result of the merger of two white dwarfs; fewer than 100 have been discovered as of 2012. The dimming is thought to be caused by carbon dust expelled by the star. As of 2012, four dimmings have been observed. PV Telescopii is a class B-type (blue) extreme helium star that is the prototype of a class of variables known as PV Telescopii variables. First discovered in 1952, it was found to have a very low level of hydrogen. One theory of its origin is that it is the result of a merger between a helium- and a carbon-oxygen white dwarf. If the combined mass does not exceed the Chandrasekhar limit, the former will accrete onto the latter star and ignite to form a supergiant. Later this will become an extreme helium star before cooling to become a white dwarf.

text: In Potsdam in 1906, the Danish astronomer Ejnar Hertzsprung noticed that the reddest stars—classified as K and M in the Harvard scheme—could be divided into two distinct groups. These stars are either much brighter than the Sun, or much fainter. To distinguish these groups, he called them "giant" and "dwarf" stars. The following year he began studying star clusters; large groupings of stars that are co-located at approximately the same distance. He published the first plots of color versus luminosity for these stars. These plots showed a prominent and continuous sequence of stars, which he named the Main Sequence.

text: The conventional color descriptions are traditional in astronomy, and represent colors relative to the mean color of an A-class star, which is considered to be white. The apparent color descriptions are what the observer would see if trying to describe the stars under a dark sky without aid to the eye, or with binoculars. However, most stars in the sky, except the brightest ones, appear white or bluish white to the unaided eye because they are too dim for color vision to work. Red supergiants are cooler and redder than dwarfs of the same spectral type, and stars with particular spectral features such as carbon stars may be far redder than any black body.

text: Lauren Murphy from The Irish Times gave only two stars out of five, commented "this unfortunately titled record is neither original nor uplifting enough to generate a high of any description." Brittany Spanos from the Rolling Stone magazine gave the album three out of five stars, stating that "even when the lyrics verge on ridiculousness [...], he's one of the biggest personalities in pop."  Maura Johnson from The Boston Globe wrote that the album is "an appealing snapshot of how Lambert has grown, and how he’s still willing to surprise his listeners and himself." Joey Guerra of the Houston Chronicle was similarly impressed, writing that the album "builds on the brash appeal that made [Lambert] a star."  Pip Ellwood of Entertainment Focus called The Original High "the strongest record that Lambert has released to date."

text: Canis Minor contains only two stars brighter than fourth magnitude. At magnitude 0.34, Procyon, or Alpha Canis Minoris, is the seventh-brightest star in the night sky, as well as one of the closest. Its name means "before the dog" or "preceding the dog" in Greek, as it rises an hour before the "Dog Star", Sirius, of Canis Major. It is a binary star system, consisting of a yellow-white main sequence star of spectral type F5 IV-V, named Procyon A, and a faint white dwarf companion of spectral type DA, named Procyon B. Procyon B, which orbits the more massive star every 41 years, is of magnitude 10.7. Procyon A is 1.4 times the Sun's mass, while its smaller companion is 0.6 times as massive as the Sun. The system is   from Earth, the shortest distance to a northern-hemisphere star of the first magnitude.  Gomeisa, or Beta Canis Minoris, with a magnitude of 2.89, is the second-brightest star in Canis Minor. Lying  from the Solar System, it is a blue-white main sequence star of spectral class B8 Ve. Although fainter to Earth observers, it is much brighter than Procyon, and is 250 times as luminous and three times as massive as the Sun.  Although its variations are slight, Gomeisa is classified as a shell star (Gamma Cassiopeiae variable), with a maximum magnitude of 2.84 and a minimum magnitude of 2.92. It is surrounded by a disk of gas which it heats and causes to emit radiation.

text: Particles that are produced in accelerators must also be observed, and this is the task of particle detectors. While interesting phenomena may occur when protons collide it is not enough to just produce them. Particle detectors must be built to detect particles, their masses, momentum, energies, lifetime, charges, and nuclear spins. In order to identify all particles produced at the interaction point where the particle beams collide, particle detectors are usually designed in layers like an onion. The layers are made up of detectors of different types, each of which is designed to observe specific types of particles.  The different traces that particles leave in each layer of the detector allow for effective particle identification and accurate measurements of energy and momentum. (The role of each layer in the detector is discussed below.) As the energy of the particles produced by the accelerator increases, the detectors attached to it must grow to effectively measure and stop higher-energy particles. ATLAS is the largest detector ever built at a particle collider.

text: There are two basic shapes of accelerators. Linear accelerators ("linacs") accelerate elementary particles along a straight path. Circular accelerators ("synchrotrons"), such as the Tevatron, the LEP, and the Large Hadron Collider (LHC), use circular paths. Circular geometry has significant advantages at energies up to and including tens of GeV: With a circular design, particles can be effectively accelerated over longer distances. Also, only a fraction of the particles brought onto a collision course actually collide. In a linear accelerator, the remaining particles are lost; in a ring accelerator, they keep circulating and are available for future collisions. The disadvantage of circular accelerators is that charged particles moving along bent paths will necessarily emit electromagnetic radiation known as synchrotron radiation. Energy loss through synchrotron radiation is inversely proportional to the fourth power of the mass of the particles in question. That is why it makes sense to build circular accelerators for heavy particles—hadron colliders such as the LHC for protons or, alternatively, for lead nuclei. An electron–positron collider of the same size would never be able to achieve the same collision energies. In fact, energies at the LEP, which used to occupy the tunnel now given over to the LHC, were limited to 209 GeV by energy loss via synchrotron radiation.

text: Once the neutron star enters the red giant, drag between the neutron star and the outer, diffuse layers of the red giant causes the binary star system's orbit to decay, and the neutron star and core of the red giant spiral inward toward one another. Depending on their initial separation, this process may take hundreds of years. When the two finally collide, the neutron star and red giant core will merge. If their combined mass exceeds the Tolman-Oppenheimer-Volkoff limit then the two will collapse into a black hole, resulting in a supernova that disperses the outer layers of the star.  Otherwise, the two will coalesce into a single neutron star.

text: Detroit has hosted five of the games. The 4th, 6th, 8th, and 9th games all took place at the Detroit Olympia. On October 8, 1950 the Red Wings, winner of the 1950 Stanley Cup Finals, played a team of All-Stars in the 4th All-Star Game. Only 9,166 people attended the game, making it is the smallest attendance figure in All-Star Game history. Ted Lindsay scored the first hat trick in an All-Star Game, as the Red Wings won 7–1. The 6th All-Star Game was held on October 5, 1952. For the second year in a row, the format had the First and Second Team All-Stars, with additional players on each team, play each other. After the game ended in a tie for the second year in a row, the NHL decided that they would continue with the previous format of the Stanley Cup winner playing an all-star team. The Red Wings won both the 1954 Stanley Cup Finals and the 1955 Stanley Cup Finals and so hosted the 8th and 9th All-Star Games, each on October 2.  The 1954 match ended in a 2–2 tie while the Red Wings won the 1955 game by a score of 3–1. The 32nd National Hockey League All-Star Game  was held at Joe Louis Arena in Detroit on February 5, 1980. The Wales Conference all-star team won for the fifth consecutive time. Gordie Howe, then of the Hartford Whalers, appeared in his twenty-third and final All-Star game, his first twenty-two coming during his career in Detroit.

text: Eclipsing variables are star systems that vary in brightness because of one star passing in front of the other rather than from any intrinsic change in luminosity. W Ursae Minoris is one such system, its magnitude ranging from 8.51 to 9.59 over 1.7 days. The combined spectrum of the system is A2V, but the masses of the two component stars are unknown. A slight change in the orbital period in 1973 suggests there is a third component of the multiple star system—most likely a red dwarf—with an orbital period of 62.2±3.9 years. RU Ursae Minoris is another example, ranging from 10 to 10.66 over 0.52 days. It is a semidetached system, as the secondary star is filling its Roche lobe and transferring matter to the primary.

text: Usually the only thing the stars in a constellation have in common is that they appear near each other in the sky when viewed from the Earth.  In galactic space, the stars of a constellation usually lie at a variety of distances. Since stars also travel on their own orbits through the Milky Way, the star patterns of the constellations change slowly over time. After tens to hundreds of thousands of years, their familiar outlines will become unrecognisable.

text: A thermonuclear weapon is a nuclear weapon that uses the energy from a primary nuclear fission reaction to compress and ignite a secondary nuclear fusion reaction. The result is greatly increased explosive power when compared to single-stage fission weapons. It is colloquially referred to as a hydrogen bomb or H-bomb because it employs fusion of isotopes of hydrogen.

text: Fred Hoyle authored the first two research papers ever published on the synthesis of the chemical elements heavier than helium by nuclear reactions in stars. The first of these  in 1946 showed that the cores of stars will evolve to temperatures of billions of degrees, much hotter than temperatures considered for thermonuclear origin of stellar power in main sequence stars. Hoyle showed that at such high temperatures the element iron can become much more abundant than other heavy elements owing to thermal equilibrium among nuclear particles, explaining the high natural abundance of iron. This idea would later be called the e Process.  Hoyle's second foundational nucleosynthesis publication showed that the elements between carbon and iron cannot be synthesized by such equilibrium processes. Hoyle attributed those elements to specific nuclear fusion reactions between abundant constituents in concentric shells of evolved massive, pre-supernova stars. This startlingly modern picture is the accepted paradigm today for the supernova nucleosynthesis of these primary elements.  In the mid 1950s, Hoyle became the leader of a group of very talented experimental and theoretical physicists who met in Cambridge:  William Alfred Fowler, Margaret Burbidge, and Geoffrey Burbidge.  This group systematized basic ideas of how all the chemical elements in our universe were manufactured, with this now being a field called nucleosynthesis.  Famously, in 1957, this group produced the BFH paper (known for the initials of the four authors) in which the field of nucleosynthesis was organized into complementary nuclear processes. They also added much new material on the synthesis of heavy elements by neutron-capture reactions, the so-called s process and the r process. So influential did the BFH paper become that for the remainder of the twentieth century it became the default citation of almost all researchers wishing to cite an accepted origin for nucleosynthesis theory, and as a result the path breaking Hoyle 1954 paper fell into obscurity. Many younger researchers appear to have never read it. Historical research in the 21st century  has brought Hoyle's 1954 paper back to scientific prominence. Those historical arguments were first presented to a gathering of nucleosynthesis experts attending a 2007 conference at Caltech organized after the deaths of both Fowler and Hoyle to celebrate the 50th anniversary of the publication of BFH. Ironically the BFH paper did not review Hoyle's 1954 supernova-shells attribution of the origin of elements between silicon and iron despite Hoyle's co authorship of BFH. Based on his many personal discussions with Hoyle  Donald D. Clayton has attributed this seemingly inexplicable oversight in BFH to the lack of proofreading by Hoyle of the draft composed at Caltech in 1956 by G.R. Burbidge and E.M. Burbidge.

text: Rey's interest in astronomy began during World War I and led to his desire to redraw constellation diagrams, which he found difficult to remember, so that they were more intuitive. This led to the 1952 publication of The Stars: A New Way to See Them, (ISBN 0-395-24830-2). His constellation diagrams were adopted widely and now appear in many astronomy guides, such as Donald H. Menzel's A Field Guide to the Stars and Planets. As of 2003 The Stars: A New Way to See Them, and a simplified presentation for children called Find the Constellations, are still in print. A new edition of Find the Constellations was released in 2008, updated with modern fonts, the new status of Pluto, and some more current measurements of planetary sizes and orbital radii.

text: A B[e] star, frequently called a B(e)-type star, is a B-type star with distinctive forbidden neutral or low ionisation emission lines in its spectrum. The designation results from combining the spectral class B, the lowercase e denoting emission in the spectral classification system, and the surrounding square brackets signifying forbidden lines.  These stars frequently also show strong hydrogen emission lines, but this feature is present in a variety of other stars and is not sufficient to classify a B[e] object.  Other observational characteristics include optical linear polarization and often infrared radiation that is much stronger than in ordinary B-class stars, called infrared excess.  As the B[e] nature is transient, B[e]-type stars might exhibit a normal B-type spectrum at times, and hitherto normal B-type stars may become B[e]-type stars.

text: The only star in the constellation to have received a name is Alfecca Meridiana or Alpha CrA. The name combines the Arabic name of the constellation with the Latin for "southern". In Arabic, Alfecca means "break", and refers to the shape of both Corona Australis and Corona Borealis. Also called simply "Meridiana", it is a white main sequence star located 130 light years away from Earth, with an apparent magnitude of 4.10 and spectral type A2Va. A rapidly rotating star, it spins at almost 200 km per second at its equator, making a complete revolution in around 14 hours. Like the star Vega, it has excess infrared radiation, which indicates it may be ringed by a disk of dust.  It is currently a main-sequence star, but will eventually evolve into a white dwarf; currently, it has a luminosity 31 times greater, and a radius and mass of 2.3 times that of the Sun. Beta Coronae Australis is an orange giant 510 light years from Earth. Its spectral type is K0II, and it is of apparent magnitude 4.11. Since its formation, it has evolved from a B-type star to a K-type star. Its luminosity class places it as a bright giant; its luminosity is 730 times that of the Sun, designating it one of the highest-luminosity K0-type stars visible to the naked eye. 100 million years old, it has a radius of 43 solar radii () and a mass of between 4.5 and 5 solar masses (). Alpha and Beta are so similar as to be indistinguishable in brightness to the naked eye.

text: ASASSN-16ma was a bright nova in the constellation Sagittarius discovered by All Sky Automated Survey for SuperNovae, which peaked at magnitude of 5.4 in early November of 2016. It is one of the brightest novae in recent history, and the brightest since V5668 Sagittarii in 2015. Being in one of the densest regions of the sky (the galactic core) it is nearly impossible to determine the culprit system, but due to the nature of the nova, a white dwarf and giant star binary system is the most likely origin.

text: A preon star is a proposed type of compact star made of preons, a group of hypothetical subatomic particles. Preon stars would be expected to have huge densities, exceeding 10 kg/m. They may have greater densities than quark stars and neutron stars although they are smaller and, therefore, less massive than white dwarfs and neutron stars. Preon stars could originate from supernova explosions or the big bang. Such objects could be detected in principle through gravitational lensing of gamma rays. Preon stars are a potential candidate for dark matter. However, current observations from particle accelerators speak against the existence of preons, or at least do not prioritize their investigation, since the only particle detector presently able to explore very high energies (the Large Hadron Collider) is not designed specifically for this, and its research program is directed towards other areas such as the Higgs boson, quark-gluon plasma and evidence related to physics beyond the Standard Model.

text: This is an A-type main sequence star with a stellar classification of A1 V. It has about 2.45 times the mass of the Sun and shines with 40 times the Sun's luminosity. This energy is being radiated into outer space at an effective temperature of 10.300 K, giving it the white-hued glow of an A-type star. It is roughly 23% of the way through its lifetime on the main sequence of core hydrogen burning stars.

text: The kicked rotator approximates systems studied in the fields of mechanics of particles, accelerator physics, plasma physics, and solid state physics. For example, circular particle accelerators accelerate particles by applying periodic kicks, as they circulate in the beam tube. Thus, the structure of the beam can be approximated by the kicked rotor.  However, this map is interesting from a fundamental point of view in physics and mathematics because it is a very simple model of a conservative system that displays Hamiltonian chaos. It is therefore useful to study the development of chaos in this kind of system.

text: There are a number of difficulties reconciling modelled and observed stellar evolution leading up to core collapse supernovae.  Red supergiants are the expected progenitors for the vast majority of core collapse supernovae, and these have been observed but only at relatively low masses and luminosities, below about  and  respectively.  Most progenitors of type II supernovae are not detected and must be considerably fainter, and presumably less massive.  It is now proposed that higher mass red supergiants do not explode as supernovae, but instead evolve back towards hotter temperatures.  Several progenitors of type IIb supernovae have been confirmed, and these were K and G supergiants, plus one A supergiant.  Yellow hypergiants or LBVs are proposed progenitors for type IIb supernovae, and almost all type IIb supernovae near enough to observe have shown such progenitors.

text: Star formation is the process by which dense regions within molecular clouds in interstellar space collapse to form stars. As a branch of astronomy, star formation includes the study of the interstellar medium and giant molecular clouds (GMC) as precursors to the star formation process, and the study of protostars and young stellar objects as its immediate products.  Star formation theory, as well as accounting for the formation of a single star, must also account for the statistics of binary stars and the initial mass function.

text: The shape and position of the Hayashi track on the Hertzsprung–Russell diagram depends on the star's mass and chemical composition. For solar-mass stars, the track lies at a temperature of roughly 4000 K. Stars on the track are nearly fully convective and have their opacity dominated by hydrogen ions. Stars less than  are fully convective even on the main sequence, but their opacity begins to be dominated by Kramers' opacity law after nuclear fusion begins, thus moving them off the Hayashi track. Stars between 0.5 and  develop a radiativezone prior to reaching the main sequence. Stars between 3 and  are fully radiative at the beginning of the pre-main-sequence. Even heavier stars are born onto the main sequence, with no PMS evolution.

text: The primary component in this system is a blue straggler, which is a type of star that is created by the interaction between two or more stars. Most likely the source of this mass transfer was the secondary member of the system, and what is now the primary star was probably once the secondary component. At an estimated age of 4 million years, this star is much younger than the age of the surrounding IC 2602 cluster, which is consistent with it being a straggler. At present the primary star has about 15 times the mass of the Sun and five times the Sun's radius. It has an intensely hot outer envelope that is radiating more than 25,000 the Sun's luminosity at an effective temperature of 31,000 K, giving it a blue-white glow. When the primary reaches the age of around 11 million years, it will expand to the point where it will begin to transfer part of its mass back to its companion. Little is known about this secondary component, but it may be an F-type star with a luminosity less than 1% of the primary.

text: These injected elements ultimately enrich the molecular clouds that are the sites of star formation. Thus, each stellar generation has a slightly different composition, going from an almost pure mixture of hydrogen and helium to a more metal-rich composition. Supernovae are the dominant mechanism for distributing these heavier elements, which are formed in a star during its period of nuclear fusion. The different abundances of elements in the material that forms a star have important influences on the star's life, and may decisively influence the possibility of having planets orbiting it.

text: This is a long-period spectroscopic binary with an orbital period of approximately 15,000 days (41 years) and an overall apparent visual magnitude of approximately 3.28. The primary of the spectroscopic binary has a stellar classification of K3 III, indicating that it is a giant star. It most likely evolved from a F-type main sequence star after consuming the hydrogen at its core. The secondary is believed to be relatively faint, as it has not been observed interferometrically. The star has two optical companions, the closest of which may be an orbiting red dwarf of class M3 with a separation of at least 900 astronomical units.

text: Diphda has an apparent visual magnitude of 2.02, making it the brightest star in Cetus. The stellar classification of this star is K0 III, although some sources list a classification of G9.5 III indicating that it lies along the dividing line separating G-type from K-type stars. The luminosity class of 'III' means that it is a giant star that has consumed the hydrogen at its core and evolved away from an A-type main sequence star. After passing through the red giant stage, it underwent the helium flash event and is generating energy through the thermonuclear fusion of helium at its core. Beta Ceti will remain in this mode for over 100 million years.

text: Different types of galaxies have different histories of star formation and hence planet formation. Planet formation is affected by the ages, metallicities, and orbits of stellar populations within a galaxy. Distribution of stellar populations within a galaxy varies between the different types of galaxies.Stars in elliptical galaxies are much older than stars in spiral galaxies. Most elliptical galaxies contain mainly low-mass stars, with minimal star-formation activity. The distribution of the different types of galaxies in the universe depends on their location within galaxy clusters, with elliptical galaxies found mostly close to their centers.

Towards the top of this transition region, the pressure is great enough that conventional nuclei will be condensed into much more massive semi-spherical collections. These formations would be unstable outside the star, due to their high neutron content and size, which can vary between tens and hundreds of nucleons. This semispherical phase is known as the gnocchi phase.

text: Sirius is a binary star system consisting of two white stars orbiting each other with a separation of about 20 AU (roughly the distance between the Sun and Uranus) and a period of 50.1 years. The brighter component, termed Sirius A, is a main-sequence star of spectral type A1V, with an estimated surface temperature of 9,940 K. Its companion, Sirius B, is a star that has already evolved off the main sequence and become a white dwarf. Currently 10,000 times less luminous in the visual spectrum, Sirius B was once the more massive of the two. The age of the system has been estimated at around 230 million years. Early in its lifespan it was thought to have been two bluish white stars orbiting each other in an elliptical orbit every 9.1 years. The system emits a higher than expected level of infrared radiation, as measured by IRAS space-based observatory. This may be an indication of dust in the system, and is considered somewhat unusual for a binary star. The Chandra X-ray Observatory image shows Sirius B outshining its bright partner as it is a brighter X-ray source.

text: This cluster is of interest because of the high number of Be stars, with a total of about 24 discovered. These are spectral class B stars that show prominent emission lines of hydrogen in their spectrum. Most of the Be stars in the cluster lie between spectral class B0 and B3. A candidate member of the cluster, LS I +61° 235, is a Be star with an X-ray binary component that has a period of about three years. There are at least five blue stragglers in the cluster. These are stars that formed by the merger of two other stars. Two of the cluster's star systems are likely eclipsing binaries with periods of 0.6 and 1.03 days.

text: A star remains near its initial position on the main sequence until a significant amount of hydrogen in the core has been consumed, then begins to evolve into a more luminous star. (On the HR diagram, the evolving star moves up and to the right of the main sequence.) Thus the main sequence represents the primary hydrogen-burning stage of a star's lifetime.

text: Another alternative was the so-called emission theory of light. As in special relativity the aether concept is discarded, yet the main difference from relativity lies in the fact that the velocity of the light source is added to that of light in accordance with the Galilean transformation. As the hypothesis of complete aether drag, it can explain the negative outcome of all aether drift experiments. Yet, there are various experiments that contradict this theory. For example, the Sagnac effect is based on the independence of light speed from the source velocity, and the image of Double stars should be scrambled according to this model—which was not observed. Also in modern experiments in particle accelerators no such velocity dependence could be observed.  These results are further confirmed by  are the De Sitter double star experiment (1913), conclusively repeated in the x-ray spectrum by K. Brecher in 1977;and the terrestrial experiment by Alväger, et al. (1963);, which all show that the speed of light is independent of the motion of the source within the limits of experimental accuracy.

text: During the formation of a Sun-like star, the object passes through the T-Tauri phase during which it is surrounded by a disk-shaped nebula. Out of this material are formed planetesimals, which can undergo an accretion process to form planets. The nebula continues to orbit the pre-main-sequence star for a period of  until it is cleared out by radiation pressure and other processes. Additional dust may then be generated about the star by collisions between the planetesimals, which forms a disk out of the resulting debris. At some point during their lifetime, at least 45% of these stars are surrounded by a debris disk, which then can be detected by the thermal emission of the dust using an infrared telescope. Repeated collisions can cause a disk to persist for much of the lifetime of a star.

text: The conditions in neutron stars are very different from those encountered on Earth, as a result of the high density and gravity of neutron stars; their masses are of order the mass of a star, but they have sizes around  in radius, which is comparable to the size of the center of large cities such as London. Neutron stars also have the property that as they become more massive, their diameter decreases. The mass of PSR J1614–2230 is the second highest of all the known neutron stars. The existence of a neutron star with such a high mass constrains the composition and structure of neutron stars, both of which are poorly understood. The reason for this is that the maximum mass of a neutron star is dependent upon its composition. A neutron star composed of matter such as hyperons or kaon condensates would collapse to form a black hole before it could reach the observed mass of PSR J1614–2230, meaning neutron star models that include such matter are strongly constrained by this result.

text: Seven star systems have been found to have planets. Nu Canis Majoris is an ageing orange giant of spectral type K1III of apparent magnitude 3.91 located around 64 light-years distant. Around 1.5 times as massive and 11 times as luminous as the Sun, it is orbited over a period of 763 days by a planet 2.6 times as massive as Jupiter. HD 47536 is likewise an ageing orange giant found to have a planetary system—echoing the fate of the Solar System in a few billion years as the Sun ages and becomes a giant. Conversely, HD 45364 is a star 107 light-years distant that is a little smaller and cooler than the Sun, of spectral type G8V, which has two planets discovered in 2008. With orbital periods of 228 and 342 days, the planets have a 3:2 orbital resonance, which helps stabilise the system. HD 47186 is another sunlike star with two planets; the inner—HD 47186 b—takes four days to complete an orbit and has been classified as a Hot Neptune, while the outer—HD 47186 c—has an eccentric 3.7-year period orbit and has a similar mass to Saturn. HD 43197 is a sunlike star around 183 light-years distant that has a Jupiter-size planet with an eccentric orbit.

text: Pulsations with a stable period, similar to those resulting from the spin of a neutron star, have never been seen from Cygnus X-1. The pulsations from neutron stars are caused by the neutron star's magnetic field, however, the no hair theorem guarantees that black holes do not have magnetic poles. For example, the X-ray binary V 0332+53 was thought to be a possible black hole until pulsations were found. Cygnus X-1 has also never displayed X-ray bursts similar to those seen from neutron stars. Cygnus X-1 unpredictably changes between two X-ray states, although the X-rays may vary continuously between those states as well. In the most common state, the X-rays are "hard", which means that more of the X-rays have high energy. In the less common state, the X-rays are "soft", with more of the X-rays having lower energy. The soft state also shows greater variability. The hard state is believed to originate in a corona surrounding the inner part of the more opaque accretion disk. The soft state occurs when the disk draws closer to the compact object (possibly as close as ), accompanied by cooling or ejection of the corona. When a new corona is generated, Cygnus X-1 transitions back to the hard state.

text: The Hayashi track is a luminosity–temperature relationship obeyed by infant stars of less than  in the pre-main-sequence phase (PMS phase) of stellar evolution. It is named after Japanese astrophysicist Chushiro Hayashi. On the Hertzsprung–Russell diagram, which plots luminosity against temperature, the track is a nearly vertical curve. After a protostar ends its phase of rapid contraction and becomes a T Tauri star, it is extremely luminous. The star continues to contract, but much more slowly.  While slowly contracting, the star follows the Hayashi track downwards, becoming several times less luminous but staying at roughly the same surface temperature, until either a radiative zone develops, at which point the star starts following the Henyey track, or nuclear fusion begins, marking its entry onto the main sequence.

text: When two massive stars are born close together from the same cloud of gas, they can form a binary system and orbit each other from birth. If those two stars are at least a few times as massive as our sun, their lives will both end in supernova explosions. The more massive star explodes first, leaving behind a neutron star. If the explosion does not kick the second star away, the binary system survives. The neutron star can now be visible as a radio pulsar, and it slowly loses energy and spins down. Later, the second star can swell up, allowing the neutron star to suck up its matter. The matter falling onto the neutron star spins it up and reduces its magnetic field. This is called "recycling" because it returns the neutron star to a quickly-spinning state. Finally, the second star also explodes in a supernova, producing another neutron star. If this second explosion also fails to disrupt the binary, a double neutron star binary is formed. Otherwise, the spun-up neutron star is left with no companion and becomes a "disrupted recycled pulsar", spinning between a few and 50 times per second.

text: Theta Apodis is a cool red giant of spectral type M7 III located  370 ± 20 light years distant. It shines with a luminosity approximately 3879 times that of the Sun and has a surface temperature of 3151 K. A semiregular variable, it varies by 0.56 magnitudes with a period of 119 days—or approximately 4 months, It is losing mass at the rate of  times the mass of the Sun per year through its stellar wind. Dusty material ejected from this star is interacting with the surrounding interstellar medium, forming a bow shock as the star moves through the galaxy. NO Apodis is a red giant of spectral type M3III that varies between magnitudes 5.71 and 5.95. Located around 883 light-years distant, it shines with a luminosity approximately 2059 times that of the Sun and has a surface temperature of 3568 K. S Apodis is a rare R Coronae Borealis variable, an extremely hydrogen-deficient supergiant thought to have arisen as the result of the merger of two white dwarfs; fewer than 100 have been discovered as of 2012. It has a baseline magnitude of 9.7. R Apodis is a star that was given a variable star designation, yet has turned out not to be variable. Of magnitude 5.3, it is another orange giant.

text: Theoretically, a red supergiant star may be too massive to explode into a supernova, and collapse directly into being a black hole, without the bright flash. They would however generate a burst of gravitational waves. This process would occur in the higher mass red supergiants, explaining the absence of observed supernovae with such progenitors.

text: Spin-down of rapidly spinning stellar mass black holes in their lowest energy state takes tens of seconds against an inner disk, representing the remnant debris of the merger of two neutron stars, the break-up of a neutron star around a companion black hole or formed in core-collapse of a massive star.

text: Both parts of Bailey's vision would, however, come true: The first game of the annual tradition, and the first official NHL All-Star Game, would be played in Maple Leaf Gardens, on October 13, 1947. The format of the All-Star Game, which remained the same, with two exceptions, until the 1967–68 NHL season, called for the defending Stanley Cup champions to play against a selection of players from the other five teams. For the first year, the All-Stars were a team composed of the First and Second NHL All-Star Teams (not to be confused with the All-Stars that played against the Cup champions), as well as three players from the New York Rangers and one player each from the Detroit Red Wings and the Chicago Black Hawks.

text: Concerns were noted during the construction of the Large Hadron Collider (LHC), which began operations in 2008, is the world's largest and highest-energy particle accelerator complex, intended to collide opposing beams of either protons or lead nuclei with very high kinetic energy. It was built by the European Organization for Nuclear Research (CERN) near Geneva, in Switzerland. The LHC's main purpose is to explore the validity and limitations of the Standard Model, the current theoretical picture for particle physics. The first particle collisions at the LHC took place shortly after startup in November 2009, at energies up to  per beam. On 30 March 2010, the first planned collisions took place between two 3.5 TeV beams, which set another new world record for the highest energy man-made particle collisions. In 2012 the beam energy was increased to 4 TeV, after upgrades in 2013 and 2014 collisions in 2015 and 2016 happened at an energy of 6.5 TeV per proton.

text: The amount of fuel available for nuclear fusion is proportional to the mass of the star. Thus, the lifetime of a star on the main sequence can be estimated by comparing it to solar evolutionary models. The Sun has been a main-sequence star for about 4.5 billion years and it will become a red giant in 6.5 billion years, for a total main sequence lifetime of roughly 10 years. Hence:

text: Cox travels to Kathmandu and visits the Pashupatinath Temple where he discusses the link between the stars and the elements of which all living things, including humans, are made. He explores the beginnings of the universe and the origins of humanity, going far back in time to look at the process of stellar evolution and comparing it to the formation cycle of the Himalayas. He describes 92 known elements found on Earth, which are mirrored in the spectrum observed through stellar classification. In northern Chile at El Tatio he compares the three states of water to the states found in the universe. He further explains how these basic elements are combined to form complexity through nuclear fusion. However, 26 more complex elements only form when stars die and eject material during a supernova. In an abandoned prison in Rio de Janeiro Cox describes the dying stages of fusion, and in the 16-to-1 Mine he describes how the rarest and heaviest elements are made. In the Atacama Desert he concludes with the recycling of matter in the Universe and the possibility that the Earth was seeded with  life from space.

text: In a 1981 paper, Thabit was observed to have nonradial pulsations over a period of around 12 hours, and has been classified as a Slowly pulsating B star. Subsequent review of Hipparcos catalog data indicated it was most likely a Beta Cephei variable, and is hence considered a candidate for that class. These are blue-white main sequence stars of around 10 to 20 times the mass of the Sun that pulsate with periods of 0.1 to 0.3 days; their changes in magnitude are much more pronounced in the ultraviolet than in the visual spectrum. It is classified as a Beta Cephei variable by the American Association of Variable Star Observers, and has an apparent magnitude of +4.62.

text: Type Ia supernovae derive their energy from a runaway nuclear fusion of a carbon-oxygen white dwarf. The details of the energetics are still not fully understood, but the end result is the ejection of the entire mass of the original star at high kinetic energy.  Around half a solar mass of that mass is Ni generated from silicon burning.  Ni is radioactive and decays into Co by beta plus decay (with a half life of six days) and gamma rays.  Co itself decays by the beta plus (an anti-electron) path with a half life of 77 days into stable Fe.  These two processes are responsible for the electromagnetic radiation from type Ia supernovae. In combination with the changing transparency of the ejected material, they produce the rapidly declining light curve.

text: Chandra X-ray imaging of NGC 1553 show diffuse hot gas making up 70% of the emissions, dotted with many point-like sources (low-mass X-ray binaries) making up the rest.  Similarly to NGC 4697 and Messier 60, these bright spots are due to binary star systems of black holes and neutron stars most of which are located in globular clusters and reflect this old galaxy's very active past.  In these systems, material pulled off a regular star is heated and gives off X-rays as it falls toward the accompanying black hole or neutron star. The brightest of the point sources is coincident with the galaxy's optical nucleus. Its luminosity and spectrum suggest its being an obscured central active galactic nucleus (AGN). This source is visible in the center of the X-ray image of NGC 1553 shown above.

text: In a physical triple star system, each star orbits the center of mass of the system. Usually, two of the stars form a close binary system, and the third orbits this pair at a distance much larger than that of the binary orbit. This arrangement is called hierarchical. The reason for this is that if the inner and outer orbits are comparable in size, the system may become dynamically unstable, leading to a star being ejected from the system. Triple stars that are not all gravitationally bound might comprise a physical binary and an optical companion, such as Beta Cephei, or rarely, a purely optical triple star, such as Gamma Serpentis.

text: A theme in Big History is what has been termed Goldilocks conditions or the Goldilocks principle, which describes how "circumstances must be right for any type of complexity to form or continue to exist," as emphasized by Spier in his recent book. For humans, bodily temperatures can neither be too hot nor too cold; for life to form on a planet, it can neither have too much nor too little energy from sunlight. Stars require sufficient quantities of hydrogen, sufficiently packed together under tremendous gravity, to cause nuclear fusion.

text: There are no strict upper limits for giant stars, but early O types become increasingly difficult to classify separately from main sequence and supergiant stars, have almost identical sizes and temperatures to the main-sequence stars from which they develop, and very short lifetimes.  A good example is Plaskett's star, a close binary consisting of two O type giants both over , temperatures over 30,000 K, and more than 100,000 times the luminosity of the Sun ().  Astronomers still differ over whether to classify at least one of the stars as a supergiant, based on subtle differences in the spectral lines.

text: With optical spectrometry, the red giant has been calculated as having a surface temperature of 3500 K and spectral type M4.5III, with around 1.3 times the Sun's mass, 86 times its radius and 1000 times its luminosity. The white dwarf is only 0.43 times the mass of the Sun. The two stars are 1.72 astronomical units (AU) apart, and take 624 days to orbit each other. The red giant also pulsates with a period of 56 days. The surface of the giant star extends to 40% of the distance to the Lagrange point L, and hence does not fill its Roche Lobe and cause the white dwarf to gain an accretion disc. The system was calculated at being around 850 parsecs (2771 light-years) distant.

text: The magnetic radiation reaction force is the result of the most fundamental calculation of the effect of self-generated fields. It arises from the observation that accelerating non-relativistic particles with associated magnetic moment emit radiation. The Abraham–Lorentz force is the average force that an accelerating charged particle feels in the recoil from the emission of radiation.  The introduction of quantum effects leads one to quantum electrodynamics. The self-fields in quantum electrodynamics generate a finite number of infinities in the calculations that can be removed by the process of renormalization. This has led to a theory that is able to make the most accurate predictions that humans have made to date. See precision tests of QED.  The renormalization process fails, however, when applied to the gravitational force. The infinities in that case are infinite in number, which causes the failure of renormalization. Therefore general relativity has unsolved self-field problems. String theory is a current attempt to resolve these problems for all forces.

text: When nuclear fusion of hydrogen becomes the dominant energy production process and the excess energy gained from gravitational contraction has been lost, the star lies along a curve on the Hertzsprung–Russell diagram (or HR diagram) called the standard main sequence. Astronomers will sometimes refer to this stage as "zero age main sequence", or ZAMS. The ZAMS curve can be calculated using computer models of stellar properties at the point when stars begin hydrogen fusion. From this point, the brightness and surface temperature of stars typically increase with age.

text: The Standard Model of particle physics is a theory which describes three of the four known fundamental interactions between the elementary particles that make up all matter. This theory allows predictions to be made about how particles will interact under many conditions. The energy per particle in a supernova is typically one to one hundred and fifty picojoules (tens to hundreds of MeV). The per-particle energy involved in a supernova is small enough that the predictions gained from the Standard Model of particle physics are likely to be basically correct. But the high densities may require corrections to the Standard Model. In particular, Earth-based particle accelerators can produce particle interactions which are of much higher energy than are found in supernovae, but these experiments involve individual particles interacting with individual particles, and it is likely that the high densities within the supernova will produce novel effects. The interactions between neutrinos and the other particles in the supernova take place with the weak nuclear force, which is believed to be well understood. However, the interactions between the protons and neutrons involve the strong nuclear force, which is much less well understood.

text: Less massive stars may develop a supergiant spectral luminosity class at relatively low luminosity, around , when they are on the asymptotic giant branch (AGB) undergoing helium shell burning.  Researchers now prefer to categorise these as AGB stars distinct from supergiants because they are less massive, have different chemical compositions at the surface, undergo different types of pulsation and variability, and will evolve in a different way, usually producing a planetary nebula and white dwarf.  Most AGB stars will not become supernovae although there is interest in a class of super-AGB stars, those almost massive enough to undergo full carbon fusion, which may produce peculiar supernovae although without ever developing an iron core.  One notable group of low mass high luminosity stars are the RV Tauri variables, AGB or post-AGB stars lying on the instability strip and showing distinctive semi-regular variations.

text: The Weather Star XL is a rack-mounted rendering computer, manufactured by Silicon Graphics, Inc., containing a modified SGI O2 computer. The O2 is an entry-level Unix workstation introduced in 1996 by SGI to replace their earlier Indy series. Like the Indy, the O2 used a single MIPS microprocessor and was intended to be used mainly for multimedia purposes; the O2 was SGI's last attempt at a low-end workstation. The Weather Star XL utilizes the SGI IRIX Operating System with custom written software for The Weather Channel. Because of the proprietary SGI hardware and software, the Weather Star XL remains the most expensive STAR system, having a manufacturing cost of $US6,500. As a result of the XL's high price, many smaller cable headends retained their Weather Star 4000 or Weather Star Jr. units until the IntelliStar was released, skipping the XL altogether.

text: Superheavy elements, such as unbinilium, are produced by nuclear fusion. These fusion reactions can be divided into "hot" and "cold" fusion, depending on the excitation energy of the compound nucleus produced. In hot fusion reactions, very light, high-energy projectiles are accelerated toward very heavy targets (actinides), giving rise to compound nuclei at high excitation energy (~40–50 MeV) that may fission, or alternatively evaporate several (3 to 5) neutrons. In cold fusion reactions (which use heavier projectiles, typically from the fourth period, and lighter targets, usually lead and bismuth), the fused nuclei produced have a relatively low excitation energy (~10–20 MeV), which decreases the probability that these products will undergo fission reactions. As the fused nuclei cool to the ground state, they require emission of only one or two neutrons. However, hot fusion reactions tend to produce more neutron-rich products because the actinides have the highest neutron-to-proton ratios of any elements that can presently be made in macroscopic quantities, and is currently the only method to produce the superheavy elements from flerovium (element 114) onwards.
