As a white dwarf cools, its radius remains the same. Why is this?



▸

because pressure due to nuclear reactions in a shell just below the surface keeps it from collapsing



▸

because pressure does not depend on temperature for a white dwarf, since the electrons are degenerate



▸

because pressure does not depend on temperature, since the star has exhausted all its nuclear fuels



▸

because material accreting onto it from a companion maintains a constant radius
