Neutron Stars, where are those protons?
« on: 21/09/2012 07:25:01 »
If protons and neutrons are bound by an extremely large force, then was it the squeezing energy of the star's collapse to unbind the protons, or were the protons all converted into neutrons due to some pressure?

The actual composition of neutron stars is well and truly up for debate.  It will be some form of degenerate matter (degenerate electron gas, neutron degenerate matter, quark gluon plasma etc) and it will vary from the outside crust to the super pressure nearing the centre.

Neutron degeneracy is when the pressure of gravity is so large that it is favourable for proton and electrons to undergo electron capture in which a proton and electron form a neutron and an electron neutrino.
