A white dwarf is the death of a medium sized star - similar to our own Sun.
The Neutron stage follows the White Dwarf stage of star development.
A white dwarf is the last stage of 97% of star evolution. A white dwarf will eventually cool down, and become a "black dwarf". Black dwarves are not expected to exist yet; to cool down to that level, it would take longer than the current age of the Universe.
A stars evolution. Our Sun will go yellow dwarf -> red giant -> white dwarf -> black dwarf.
the next stage of a white dwarf is the black dwarf which is form when the degenerate electron slowly cools down by thermal radiation but the time required for a white dwarf to become a black dwarf is bigger than the current age of universe so the evidence of a black dwarf isn't found yet
A white dwarf is the last stage of stellar evolution for stars with masses similar to our Sun. A black hole, on the other hand, is the last stage of stellar evolution for stars having very large masses, many times greater than that of the Sun. Consequently, very few stars end up as black holes. Additionally, black holes have an escape velocity greater than the speed of light, while a white dwarf's escape velocity is less than the speed of light.
White dwarf stage. Note that not all stars reach this stage. Some stars experience runaway criticality and go supernova. Also, white dwarf stars in binary systems can still go nova if they are acquiring hydrogen from their partner.
The red giant stage, where a star like our sun swells to a much larger size. Then it collapses into a white dwarf.
A white dwarf is a star that is dying and is in its final evolutionary stage.
White Dwarf then Black Dwarf=Dead Star
