Quizplus · Accepted Answer

Electron-degeneracy pressure is a quantum mechanical effect that arises from the reluctance of electrons to be squeezed too closely together. This pressure is independent of temperature but increases with density. Therefore, when helium fusion begins in the core of a red giant star, the increasing temperature causes the fusion rate to rise, which in turn increases the energy output of the star. This causes the core to heat up and become more dense, but electron-degeneracy pressure does not increase to counteract the gravitational force. As a result, the core collapses and heats up until the next stage of nuclear burning begins.
