What is a star formed from a white dwarf that has lost its energy?
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.
What comes before white dwarf and after white dwarf?
Before a white dwarf, a star would undergo the red giant phase. After a white dwarf, a star may end its life cycle as a black dwarf, although no black dwarfs are currently known to exist in the universe due to the long timescales required for a white dwarf to cool down.
Is a dwarf star bigger than your sun?
Depends what type of dwarf star. - Our Sun is a yellow dwarf.
Is a yellow star a supergiant?
