Meaning
A white dwarf is a low mass star which has run out of low mass elements to fuse.
About White Dwarves
- A white dwarf is formed from the core of a red giant after it has run out of Helium.
- A white dwarf glows due to its gravitational collapse transferring energy from the gravitational potential energy store of its matter to the thermal energy store of its matter.
- A white dwarf is a hot, dense ball of Carbon around the size of planet Earth.
