The words neutron degeneracy pressure and electron degeneracy pressure are thrown around a lot when talk of white dwarfs, neutron stars, and black holes comes up. Despite this, I can't find a quantitative description of these critical pressures ANYWHERE. It is almost always described in terms of solar masses or density, never pressure. How much pressure is required to keep matter degenerate? I wouldn't think it would be this hard to find the answer. I know you could find the answer using the density and gravitational pull, but I doubt newton's law of gravitation is still valid under these conditions, so I don't know how to calculate the gravitational pull either. Can anybody help?
