black dwarf |
A dead star that is no longer luminous. The final luminous phase in the evolution of a star less massive than about 1.4 solar masses is spent as a white dwarf. Since no new energy is generated in a white dwarf, all possible sources having been exhausted, the star's final fate is to gradually cool and fade to a dark stellar "corpse". However, the universe is not yet old enough for any black dwarfs to have formed. |
