Stars much heavier than our sun will not form white dwarf, but collapse further, becoming (if condition are right) neutron stars. They result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past white dwarf star density to that of atomic nuclei. Eventually neutron degeneracy pressure stabilizes the collapse, just as the electron does for white dwarfs. The Fermi Energy is given by where Z/A =1 and V corresponds to volume. The neutron...

Neutron stars are created when giant stars die in supernovas and their remaining cores collapse to a state of immense density where protons and electrons combine to form neutrons. A neutron star is ~1.4 times as massive as the sun and has radius of only ~10 km. For this neutron star compute its escape velocity. What percentage of the speed of light does this correspond to? (Assume for the mass of the sun, M = 1.989 x 10^30 kg).

10. At the end of the Sun’s life it will use up the hydrogen and helium in its core and become a white dwarf. The Sun’s mass is 2.0 × 1030 kg, its radius is 7.0 × 105 km, and it has a rotational period of approximately 28 days. If the Sun should collapse into a white dwarf of radius 3.5 × 103 km, what would its period be if no mass were ejected and a sphere of uniform density...
