In contrast to active stars, what counterintuitive physical behavior is exhibited by white dwarfs as their mass increases beyond normal stellar behavior?

Answer

Their radius shrinks as mass increases

The relationship is decoupled in white dwarfs: compression increases the degeneracy pressure without increasing heat from fusion, causing the radius to shrink as mass increases, which is opposite to how normal stars behave.
