White Dwarfs
White dwarfs develop when a star from maximum 1.4 solar masses dies. These stars are not heavy enough to generate the core temperatures required to fuse carbon in nucleosynthesis reactions and after they have become a red giant during their helium-burning phase, they will shed their outer layers to form a planetary nebula, leaving behind an inert core consisting mostly of carbon and oxygen....
