Question

Quizplus · Accepted Answer

A white dwarf star is prevented from collapsing by degenerate electron gas pressure. Degenerate matter is matter that has been compressed to a point where the quantum mechanical properties of electrons become important in determining its structure, rather than thermal motion. This creates a pressure that can support the star against gravity.
