They form in close binary systems, one component being a white dwarf accreting matter from the other ordinary star component, and may recur over periods of decades to centuries or millennia.

The electron gas in ordinary metals and in the interior of white dwarf stars constitute two examples of a degenerate electron gas.

Blue giants should not be confused with blue supergiants such as Rigel or ordinary hydrogen-fusing O to B stars such as Regulus which is a main sequence dwarf star.

Within the history of the game, the black orcs were created magically from the ordinary orc by Chaos Dwarf sorcerers in an attempt to engineer a superior slave ( chaos dwarf generals were allowed to field many orc and goblin units in their armies ).

Some Boeotian vase-paintings show a caricature version of the episode, acted out by dwarf pygmies with negroid attributes, and an aged and lame Odysseus leaning on a staff ; they are the mute survivors of some rustic comedy tradition that is impenetrable to us.

De Camp and Ley also claim that Sir John Leslie expanded on Euler's idea, suggesting two central suns named Pluto and Proserpine ( this was unrelated to the dwarf planet Pluto, which was discovered and named some time later ).

The dependence of the hydrogen fusion rate on temperature and pressure means that it is only when it is compressed and heated at the surface of the white dwarf to a temperature of some 20 million kelvin that a nuclear fusion reaction occurs ; at these temperatures, hydrogen burns via the CNO cycle.

Recent astrophysical models suggest that red dwarfs of 0. 1 solar mass may stay on the main sequence for some six to twelve trillion years, and take several hundred billion more to slowly collapse into a white dwarf.

* The prelaunched fuel would provide some visibility into the interstellar medium-thus alerting the trailing spacecraft of unseen hazards ( e. g. brown dwarf stars ).

The plant structure varies between species – some trail along the ground, some are dwarf shrubs, and some are larger shrubs perhaps tall.

While cloud forest today is the most widely used term, in some regions these ecosystems or special types of cloud forests are called mossy forest, elfin forest, montane thicket, dwarf cloud forest, nuboselva, bosque montano nebuloso, selva de neblina, bosque nuboso, bosque de ceja, selva sublada, nebelwald, wolkenwald, forêt néphéliphile, forêt de nuage, unmu-rin, bosque anao, foresta nebular, mata nebular, matinha nebular, floresta fe neblina, floresta nuvigena, mata de neblina, matinha de altitude, floresta nublada, and floresta pluvial e / ou alto.

" Unquestionably, the figure in outline was exactly like a human being, walking upright and stopping occasionally to pull at some dwarf rhododendron bushes.

understood, it is not known precisely how long it will take white dwarfs to cool to blackness .< sup >, § IIIE, IVA .</ sup > Barrow and Tipler estimate that it would take 10 < sup > 15 </ sup > years for a white dwarf to cool to 5 K ; however, if weakly interacting massive particles exist, it is possible that interactions with these particles will keep some white dwarfs much warmer than this for approximately 10 < sup > 25 </ sup > years .< sup >, § IIIE .</ sup > If protons are not stable, white dwarfs will also be kept warm by energy released from proton decay.

On the evening of September 26, 2012, some dwarf resident with a terrible mullet came into the Mankato hospital ER and threatned staff members.

In some cases the magnetic field of the white dwarf is strong enough to disrupt the inner accretion disk or even prevent disk formation altogether.

There are still models for hypernova explosions produced from binary systems, white dwarf or neutron stars in unusual arrangements or undergoing mergers, and some of these are proposed to account for gamma-ray bursts.

As with many other rich galaxy clusters, Virgo's intracluster medium is filled with a hot, rarefied plasma at temperatures of 30 million Kelvin that emits X-Rays, and within it can be found a large number of intergalactic stars ( up to 10 % of the stars in the cluster ), including some planetary nebulae, that it's theorized were expelled of their home galaxies on interactions with other galaxies, as well as some globular clusters, possibly stripped of dwarf galaxies, and even at least one star formation region

Astronomers initially ruled out the possibility that some of the point-like objects are white dwarfs, because they are too blue to be consistent with theories of white dwarf evolution prevalent at the time.

Fishes in the Mackenzie River proper include the northern pike, some minnows, and lake whitefish, and the river's shores are lined with sparse vegetation like dwarf birch and willows, as well as numerous peat bogs.

The dwarf form has a distribution completely separate from the other forms, living in southern oceans, and has a distribution generally north of the Antarctic species, although there is some overlap.

For instance, the world of New Washington and its sister planet Franklin orbit a red dwarf at some distance from the solar system.

African examples are the haplochromines, such as the mbuna and the dwarf mouthbrooders Pseudocrenilabrus multicolor, and some of the tilapiines, such as Oreochromis mossambicus and Oreochromis niloticus.

After some months in London, Lambert was visited by Józef Boruwłaski, a 3-foot 3-inch ( 99 cm ) dwarf then in his seventies.

They have also been reported to eat some deep-sea shrimps, but, compared with dwarf sperm whales, relatively few fish.

The dimensions of these waves dwarf all our usual standards of measurement.

For example, these are all elements he includes in “ Hop-Frog .” The title character, a dwarf taken from his homeland, becomes the jester of a king particularly fond of practical jokes.

The Milky Way and the Andromeda Galaxy are the two brightest galaxies within the group ; many of the other member galaxies are dwarf companions of these two galaxies.

Two dwarf species, named Orcinus nanus and Orcinus glacialis, were described during the 1980s by Soviet researchers, but most cetacean researchers are skeptical about their status, and linking these directly to the types described below is difficult.

To distinguish these groups, he called them " giant " and " dwarf " stars.

When he plotted the spectral types of these stars against their absolute magnitude, he found that dwarf stars followed a distinct relationship.

Parametrically, these clusters lie somewhere between a ( low dark matter ) globular cluster and a ( dark matter-dominated ) dwarf spheroidal galaxy.

Despite these suspicions, the first non-classical white dwarf was not definitely identified until the 1930s.

In order to test these predictions, it is necessary to reconstruct the primordial abundances as faithfully as possible, for instance by observing astronomical objects in which very little stellar nucleosynthesis has taken place ( such as certain dwarf galaxies ) or by observing objects that are very far away, and thus can be seen in a very early stage of their evolution ( such as distant quasars ).

It is, finally, not excluded that the myth of these " little / dwarf men vazimba " was led by the Austronesian from Sunda Islands where they lived before, in which case this myth could actually relate to the Flores hominid type or, more probably, the Negritos ( Orang Asli in Malay ).

Thus far, nine skeletons of Homo floresiensis dating from approximately 38, 000 to 13, 000 years ago have been excavated, suggesting that these " hobbits " would have shared the island with dwarf elephants, giant rats, and Komodo dragons.

The terms " dwarf ", " little person ", " LP ", and " person of short stature " are now generally considered acceptable by most people affected by these disorders.

In addition, the translation of these documents are difficult because in the past the term " Wa " was derogatory meaning " midget pirate " or " dwarf pirate ".

Magnetic systems often show strong and variable polarization in their optical light, and are therefore sometimes called polars ; these often exhibit small-amplitude brightness fluctuations at what's presumed to be the period of rotation of the white dwarf

Astronomers have long thought it was quite likely that many undiscovered dwarf stars exist within 20 light years of Earth, as stellar population surveys show the count of known nearby dwarf stars to be lower than otherwise expected and these stars are dim and easily overlooked.

Based upon their element abundances, these stars may once have been members of Omega Centauri, a globular cluster that is thought to be the remnant of a dwarf galaxy that merged with the Milky Way.

The discovery of low-mass white dwarf companions around two blue stragglers in the Kepler field suggests these two blue stragglers gained mass via stable mass transfer.

To distinguish these groups, he called them " giant " and " dwarf " stars.

It is not well understood how or why these special white dwarf stars form from a star which should, in theory, end up a small supernova.
