The term dwarfstar refers to a variety of distinct classes of star s. Dwarfstar alone generally refers to any main sequence main sequence star, a star of Stellar classification Yerkes spectral classification luminosity class V. Red dwarf s are low mass main sequence stars. Yellow dwarf s are main sequence dwarf stars with masses comparable to that of the Sun . The Sun is a yellow dwarf. A Blue dwarf red dwarf stage blue dwarf is a low mass star which is hypothesized to be the post main sequence form of a red dwarf. A white dwarf is a star composed of electron degenerate matter , thought to be the final stage in the evolution of stars not massive enough to undergo a Type II supernova &mdash stars less massive than roughly 9 solar mass es. A black dwarf refers to a white dwarf that has cooled sufficiently such that it no longer emits any visible light. A brown dwarf is a sub stellar object not massive enough to ever fuse hydrogen into helium , but still massive enough to fuse deuterium &mdash less than about 0.08 solar masses and more than about 13 Jupiter masses.

Eager year 2007 month February ref The name is a medieval fantasy complement to ELF that has no official meaning, although the backronym Debugging With Attributed Record Formats was later proposed. ref name eager History The first version of DWARF proved to use excessive amounts of storage, and an incompatible successor, DWARF 2, superseded it and added various encoding schemes to reduce data size. DWARF was not immediately successful for instance, when Sun Microsystems adopted ELF as part of their move to Solaris operating system Solaris , they opted to continue using stabs , in an embedding known as stabs in elf .

Other uses star nav A black dwarf is a hypothetical stellar remnant , created when a white dwarf becomes sufficiently cool to no longer emit significant heat or light . Since the time required for a white dwarf to reach this state is calculated to be longer than the current age of the universe 13.7 billion years , no black dwarfs are expected to exist in the universe yet, and the temperature of the coolest white dwarfs is one observational limit on the age of the universe . A white dwarf is what remains of a main sequence star of low or medium mass below approximately 9 to 10 solar mass es , after it has either expelled or nuclear fusion fused all the chemical element element s which it has sufficient temperature to fuse. ref § 3, cite journal author Heger, A.
