dwarf

It contains several million stars, most of which are yellow dwarf stars, but also possesses red giants and blue-white stars ; the stars have an average age of 12 billion years.

This has prompted suspicion that Omega Centauri was the core of a dwarf galaxy that had been absorbed by the Milky Way.

Both components are orange-hued dwarf ( main sequence ) stars ; the primary is of magnitude 5. 2 and the secondary is of magnitude 6. 1.

* AM CVn, a very blue star of magnitude 14, is the prototype of a special class of cataclysmic variable stars, in which the companion star is a white dwarf, rather than a main sequence star.

Dwarf elephants, dwarf hippopotamus, and dwarf deer were native to Pleistocene Crete.

Although he is best known for discovering the dwarf planet Pluto in 1930, the first object to be discovered in what would later be identified as the Kuiper belt, Tombaugh also discovered many asteroids ; he also called for serious scientific research of unidentified flying objects.

The name " Pluto " was reportedly suggested by Venetia Burney, then an 11-year-old English school girl, who died in April 2009, having lived to see the reclassification of Pluto as a dwarf planet.

After it was shown that at least one such body was larger than Pluto, on August 24, 2006 the International Astronomical Union ( IAU ) reclassified Pluto, grouping it with two similarly sized " dwarf planets " rather than with the eight " classical planets ".

The Chandrasekhar limit () is the maximum mass of a stable white dwarf star.

Radius – mass relations for a model white dwarf.

Solving the hydrostatic equation then leads to a model white dwarf which is a polytrope of index 3 / 2 and therefore has radius inversely proportional to the cube root of its mass, and volume inversely proportional to its mass.

As the mass of a model white dwarf increases, the typical energies to which degeneracy pressure forces the electrons are no longer negligible relative to their rest masses.

If a main-sequence star is not too massive ( less than approximately 8 solar masses ), it will eventually shed enough mass to form a white dwarf having mass below the Chandrasekhar limit, which will consist of the former core of the star.

Type Ia supernovae derive their energy from runaway fusion of the nuclei in the interior of a white dwarf.

According to a group of astronomers at the University of Toronto and elsewhere, the observations of this supernova are best explained by assuming that it arose from a white dwarf which grew to twice the mass of the Sun before exploding.

One way to potentially explain the problem of the Champagne Supernova was considering it the result of an aspherical explosion of a white dwarf.

Cranberries are a group of evergreen dwarf shrubs or trailing vines in the subgenus Oxycoccus of the genus Vaccinium.

The word chaparral is a loan word from Spanish chaparro, meaning both " small " and " dwarf " evergreen oak, which itself comes from the Basque word txapar, with exactly the same meaning.

Less commonly seen animals include cuvier's beaked whale, false killer whale, pygmy sperm whale, dwarf sperm whale, risso's dolphin, common dolphin, humpback whale and Bryde's whale.

Innovations were also introduced into the regular gladiatorial games such as naval contests, nighttime battles, and female and dwarf gladiator fights.
