A white dwarf (or degenerative star) is the stellar remains of a star, that is composed mostly of electron degenerate matter. The electrons are already at the lowest possible energy level.
A white dwarf's mass is comparable to that of the Sun but its volume is comparable to that of the Earth.

Do stars die out after becoming white dwarfs?
No. Stars become white dwarfs after dying.
Why do all white dwarfs have about the same mass?
