8 01 15 Constants | Periodic Table The neutrons in a neutron star (Chapter 44 in the Part A textbook) can be treated as a Fermi gas with neutrons in place of the electrons in our model of an electron gas. Determine the Fermi energy for a neutron star of radius 15 km and mass 2.2 times that of our Sun. Assume that the star is made entirely of neutrons and is of uniform density.
