Thomas—Fermi nuclei in neutron star matter

  • Published:
Acta Physica Academiae Scientiarum Hungaricae

Abstract

The nuclear structure of zero temperature neutron star matter is investigated in the density region ϱ=1011−1014 g/cm3. The energy of a nucleus embedded into a nucleon liquid is calculated in the Thomas-Fermi approximation. We find that the beginning of the neutron drip is a first order transition of phase at the critical pressureP=2.0×1030 dyn/cm2. The resulting equation of state is compared with previous predictions and the inside structure of neutron stars are determined by integrating theOppenheimer—Volkoff equations.
