- WHITE DWARF
-
- When a star of a certain size (less than 8 solar masses) has used up its fuels for fusion reactions, it goes through a giant
- phase and then ends up as a dense star about the size of the Earth, weighing about the mass of the Sun or less. A star
- like this is called a white dwarf. The name white dwarf is misleading, as the star's colour changes with age, sometimes
- ending as a black sphere, called a black dwarf.
-
- There are an estimated ten billion white dwarfs in our Galaxy. The more mass a dwarf has, the smaller its diameter and
- greater its density. The density of a typical white dwarf is three tons per cubic centimetres. In other words one litre of
- white dwarf matter would weigh as much as a medium size ship.
