Birth and Life of a Star
... Many white dwarfs are about the same size as the Earth, and about 100 times smaller than the Sun. They may weigh the same as the sun, which would make them very dense. The heavier the white dwarf is, then the smaller its size will be. A star like our Sun will become a white dwarf when it has run out ...

... Another way to blow up a star is to consider the evolution of a star with 8 times the mass of the Sun (or more). These stars are very rare. Only one in a thousand stars formed has this much mass. An 8 solar mass star will not live for 10 billion years converting hydrogen into helium in its core. ...
