Yesterday i had a thought about when our sun runs out of energy and collapses into a white dwarf, it is my understanding when this happens a white dwarf is held up by electron degeneracy, all the electrons are under immense pressure but cannot fall to the lowest energy state therefore stopping the star from collapse due to gravity.
My question is how can this star still emit light as the electrons cannot change energy levels?
Unless my understanding of degeneracy is wrong and they can in fact change energy levels, if this is the case would anyone care to explain?
thanks
