They are a form of dark matter. |   | uncertainty principle | 
| black dwarf | dark halo | greater than 1000 Kelvin | hypothetical | inversely proportional to the wavelength | determined from proper motion and radial velocity | which depends on luminosity class | from the point of view of Earth's orbit | from the point of view of Earth | d | which is diffused out from the hotter core | MACHO | gravitational contraction and or fusion | which takes place primarily within the core | star catalog | inversely proportional to its momentum | massive compact halo object | hydrogen, helium | greater than 0.08 the sun's mass | main sequence star | The final stage in the evolution of a star of roughly 1 Msun. It is a mass of cold, electron-degenerate gas, and can no longer radiate energy, because the whole star is in its lowest energy state. No black dwarfs have ever been observed. Also, an object (M < 0.085 Msun) that is not massive enough to achieve nuclear chain reactions. | V | uncertainty principle |
