Nuclear fusion stops at iron in the core of the star, and the iron ash core collapses under its own gravity. Electron degeneracy
pressure stops the core collapse in a low-mass star, but the self-gravity of high-mass stars is large enough to overcome this, and the electrons slam into protons to form neutrons. Like electrons, neutrons are not able to exist within a certain distance of one another.As the core collapses, the neutrons hit this limit in density, and a new, extremely strong outward pressure called neutron degeneracy pressure appears. What effect might this have on the material outside the neutron degenerate core, which was previously collapsing under gravity?Choose one:A. It will continue to collapse at the same rate.B. It will collapse faster.C. It will expand outward.
