Describe white dwarfs.

White Dwarf is the end stage of the stars having mass less than 8 times the mass of Sun. At the end of the evolution these stars explode. The outer envelope is thrown out and the inner parts contracts.

White Dwarfs look white and are of small size similar to the size of earth.

The mass of white dwarf is very large as compared to earth and so density is very high.

The white dwarf is the end stage of the star, when the nuclear fuel is exhausted. The hot core of the star is left in the end.
