Neutron Stars The period at the end of a massive star’s life Left behind by supernovae after star went through main sequence life and multiple shell burning Comparison WD vs. Neutron Star o WD about the size of earth, radiates light into space, cooling as it loses energy, extremely dense, supported by electron degeneracy pressure o NS Dead cores of massive stars Supported by neutron degeneracy pressure No electrons, but NDP follows same properties Cools as it loses energy 1 trillion lbs in 1 cubic cm could be lots of dead NS we don’t know about in space Formation o Iron catastrophe: core of iron forms at end of massive star o Produced by the infall/collapse of the massive core of a massive star Can not be larger than 3-5 solar masses, similar to but higher than the WD limit o Exact value of this limit is unknown for Neutron stars since neutrons are not fundamental particles (neutrons composed of sub-particles called quarks) Spin At Birth
