Consider the sun, of mass Ms = 2×10^30 kg, to be a plasma of completely ionized H atoms, of diameter 1.3×10^6 km. If the surface temperature of the sun is 6,000 K, suppose the sun collapses to form a neutron star, again with the same mass. Assuming a uniform density, what will be the Fermi energy of the nucleons, in both eV and in temperature units?
