According to the historian of science Norwood Russell Hanson: There is no bilaterally-symmetrical, nor excentrically-periodic curve used in any branch of astrophysics or observational astronomy which could not be smoothly plotted as the resultant motion of a point turning within a constellation of epicycles, finite in number, revolving around a fixed deferent. Any path — periodic or not, closed or open — can be represented with an infinite number of epicycles.

Far-infrared astronomy is the branch of astronomy and astrophysics that deals with objects visible in far-infrared radiation ( extending from 30 µm towards submillimeter wavelengths around 450 µm ).

The star contracts, although not all the way to the main sequence, and it migrates to the horizontal branch on the HR-diagram, gradually shrinking in radius and increasing its surface temperature.

The star follows the asymptotic giant branch on the H-R diagram, paralleling the original red giant evolution, but with even faster energy generation ( which lasts for a shorter time ).

In this last stage the star will observationally be a red giant again and structurally an asymptotic giant branch star.

After the asymptotic giant branch ( AGB ) phase, the short planetary nebula phase of stellar evolution begins as gases drift away from the central star at speeds of a few kilometers per second.

Examples include " Morgenstern " (" morning star "), " Safire " (" sapphire "), and " Reis " (" branch ").

The spectrum of this star matches a stellar classification of, with the luminosity class of III indicating that it is an evolved giant star that has exhausted the supply of hydrogen at its core and is now on the red giant branch.

Within the last two thousand years, the central star of the Ring Nebula has left the asymptotic giant branch after exhausting its supply of hydrogen fuel.

Once a star with about 0. 5 – 10 times the mass of the Sun has consumed nearly all the hydrogen at its core, it begins to evolve up the red giant branch.

This process is predicted to happen to all Mira variables, but the relatively short duration of thermal pulses ( a few thousand years ) over the asymptotic giant branch lifetime of the star ( a few million years ), means we only see it in a few of the several thousand Mira stars known, possibly in R Hydrae.

V838 Monocerotis may be a post-asymptotic giant branch star, on the verge of its death.

Other presolar grains ( AGB star grains ) provide isotopic and physical information on asymptotic giant branch stars, which have manufactured the lion's share of the refractory elements lighter than iron in the galaxy.

The previous version was an outright evil villain, willing to blackmail and force his way into stardom ( as opposed to the current Count, who merely tries to get in the legitimate way ) and was fixated on being a TV star, rather than settle for fame in some other branch of entertainment.

Astrophysics ( Greek: Astro-meaning " star ", and Greek: physis – φύσις-meaning " nature ") is the branch of astronomy that deals with the physics of the universe, including the physical properties of celestial objects, as well as their interactions and behavior.

* III-All placed on a sword in pale, pommelled gold, hilted blue, except for the center part, which is red and contains a silver star, all upon a crown formed by a branch of coffee fruited on the dexter side and another of flowering tobacco on the sinister side, both in proper colors, tied blue, the whole assembled on a splendor of gold, the contours of which form a star of 20 points

Perhaps the most bruising encounter between WIA and popular entertainment was the 1995 film Black and Blue which featured a covert recording of a performance by the veteran comedian Bernard Manning as the star of a charity function organised by the Manchester branch of the Police Federation, which represents rank-and-file officers.

During this portion of its evolution, labeled the subgiant branch on the Hertzsprung – Russell diagram, the luminosity of the star remains approximately constant and its surface temperature decreases.

Eventually the star will start to ascend the red giant branch on the Hertzsprung – Russell diagram.

The luminosity of the star decreases, its outer envelope contracts again, and the star leaves the red giant branch.

If not very massive, it may be found in the horizontal branch on the Hertzsprung – Russell diagram, or its position in the diagram may move in loops .< sup >, chapter 6 .</ sup > If the star is not heavier than approximately 8 solar masses, it will eventually exhaust the helium at its core and begin to fuse helium in a shell around the core.

In this way, morphology is the branch of linguistics that studies patterns of word formation within and across languages, and attempts to formulate rules that model the knowledge of the speakers of those languages.

Prior to the formation of the OSS ( the American version of the British Secret Intelligence Service and Special Operations Executive ), American intelligence had been conducted on an ad-hoc basis by the various departments of the executive branch, including the State, Treasury, Navy, and War Departments.

During the war, Alexander Dubček joined the Communist Party of Slovakia ( KSS ), which had been created after the formation of the Slovak state and in 1948 was transformed into the Slovak branch of the Communist Party of Czechoslovakia ( KSČ ).

By means of these scars one can determine the age of any young branch, since each year's growth ends in the formation of a bud, the formation of which produces an additional group of bud scale scars.

Among the activities of this group were the organization of a Miss Nazi beauty contest and the formation of a Chilean branch of the Ku Klux Klan.

" Tillemont, possibly influenced by the fact that no honour is paid to the memory of Nicolas by any branch of the Church, allows more weight to the testimony against him ; rejects peremptorily Cassian's statement — to which Neander gives his adhesion — that some other Nicolas was the founder of the sect ; and concludes that if not the actual founder, he was so unfortunate as to give occasion to the formation of the sect, by his indiscreet speaking.

Its origins go back to the formation of the American branch of Decca Records in 1934.

* Physical cosmology, a branch of astronomy, is the study of the largest-scale structures and dynamics of the universe and is concerned with fundamental questions about its formation and evolution

In particular the Act restricts the formation of such committees to only those which are deemed essential, limits their powers to provision of advice to officers and agencies in the executive branch of the Federal Government, and limits the length of term during which any such committee may operate.

After the formation of London Transport in 1933 this branch became part of the LU Metropolitan Line and was later transferred to the Bakerloo Line in 1939 then to the Jubilee Line in 1979.

The Marxist branch tended to support the formation of workers ' or socialist parties that participated in parliamentary politics in Western liberal democracies to advance their agendas, while anarchists tended to criticize parliamentary politics as not being sufficiently democratic " from the bottom up " and as providing no democratic control over the workplace and the means of production.

The American organization being largely inoperative at the time, he undertook the formation and institution of a branch of the Fraternity in the Western Hemisphere that would devote itself exclusively and assiduously to the true Rosicrucian Art and Operation, open to both sexes on a basis of true equality.

Not long after its formation the BM gained coverage in Leicester, where a growing Midlands branch was being organised by Ray Hill, when local members attacked students who were supporting an Anti-Apartheid Movement protest against a South African trade delegation visiting the city.

The main nerves branch repeatedly, then attach to the lower side of each plate in the batteries, which are composed of hexagonal columns, in honeycomb formation: each column consists of 140 to half a million gelatinous plates.

In 1858 a branch line was constructed through the heart of what was then the hamlet of Brownhills, which led to a migration of the population eastwards, leading to the formation of mining slums in the Ogley Hay area.
