The “degenerate” nature of the matter means that the pressure is effectively insensitive to temperature (there might be some interesting effects at the ‘surface’). It’s one of these totally weird quantum effects; even at 0K degenerate matter ‘contains’ a lot of energy in the form of the ‘speed’ of the particles!

I was reading some on black dwarfs and degenerate matter, and I see descriptions of what they’re like when it’s a white dwarf…but what about once all the energy has radiated away? I read that the pressure of the degenerate gas depends on the speed of its particles…so would that place a lower limit on how cool it could get before collapsing further into, say, a neutron star? Because as it cools closer to absolute zero, wouldn’t the particles have to slow down and be unable to maintain enough pressure to keep it from collapsing further? Or am I thinking about this incorrectly?
