What unique phase change occurs in a white dwarf's plasma as it cools significantly during its late life?

Answer

Crystallization into an ordered crystalline lattice structure.

As the temperature drops sufficiently, the atomic nuclei within the degenerate plasma can transition from a disordered liquid state to an ordered crystalline lattice structure, releasing latent heat in the process.
