Question

Quizplus · Accepted Answer

The more massive a white dwarf, the greater the gravitational force acting on its interior. This causes the electrons in the white dwarf to become more tightly packed, resulting in a higher density. A higher density leads to a smaller radius due to increased electron degeneracy pressure, which creates a stable equilibrium between the outward pressure of electron degeneracy and the inward pull of gravity.
