Organizing and summarizing search results for youWhite dwarfs are formed through the following process:- Stars like our sun fuse hydrogen in their cores into helium.
- White dwarfs are stars that have burned up all of the hydrogen they once used as nuclear fuel.
- White dwarfs evolve from stars with an initial mass of up to three or four solar masses.
- They form when the hot planetary nebula created by a red giant star loses its envelope.
- The remaining core becomes a very hot white dwarf.
