SUMMARY
After a star exhausts its nuclear fuel and reaches an iron core, if it lacks sufficient mass, it will evolve into a white or brown dwarf. White dwarfs cool over extensive periods, eventually reaching thermal equilibrium with the universe, potentially below 1 Kelvin. In contrast, massive stars that produce iron will undergo a supernova, resulting in either a neutron star or a stellar-mass black hole. The cooling process of white dwarfs leads to large, cold spherical objects primarily composed of carbon, oxygen, and other dense elements.
