What type of pressure primarily supports a white dwarf against gravitational collapse?

Answer

Electron degeneracy pressure

The primary support mechanism in a white dwarf is electron degeneracy pressure, a quantum mechanical phenomenon arising from the Pauli Exclusion Principle, which opposes gravity even without high temperatures sustaining thermal pressure.
