11. Likewise, degenerate matter still has normal thermal pressure, but at extremely high densities, the degeneracy pressure usually dominates. 12. If preons exist, preon-degenerate matter might occur at densities greater than that which can be supported by quark-degenerate matter . 13. Quark-degenerate matter may occur in the cores of neutron stars, depending on the equations of state of neutron-degenerate matter. 14. If preons exist, preon-degenerate matter might occur at densities greater than that which can be supported by quark-degenerate matter. 15. Quark-degenerate matter may occur in the cores of neutron stars, depending on the equations of state of neutron-degenerate matter . 16. The white dwarf consists of degenerate matter , and so is largely unresponsive to heat, while the accreted hydrogen is not. 17. Hypothetically, there is a spherical crystal of ( neutronium / nihilon / neutron degenerate matter ) with a 1 cm diametre. 18. The equation of state for degenerate matter is " soft ", meaning that adding more mass will result in a smaller object. 19. :: Agreed-I think we are talking about degenerate matter here, but I don't see how that can be constructed just from protons alone. 20. A fluid of neutrons at 0 K will probably be a form of degenerate matter , suggesting an inherent pressure related to their density.
