Abstract：
We study the properties of the outer crust of nonaccreting cold neutron stars using a liquid-drop model based on a microscopic Brueckner-Hartree-Fock energy-density functional. We calculate an extended nuclear mass table, particularly near the neutron drip line. Combined with the latest experimental binding energies from AME2020, we determine the sequence of equilibrium nuclei and construct the equation of state for the outer crust. Various properties of the outer crust are calculated in detail and compared with those from other crust models.
