Description

A consistent Hartree-Fock study of the hot, beta-stable baryonic matter of proto-neutron star (PNS) is done based on several choices of the effective (density dependent) nucleon-nucleon interaction, which have been successfully used in different nuclear structure and reaction studies. The equations of state associated with different behaviors of the symmetry energy at supranuclear densities were used to study the npe-muon-neutrino composition of the hot PNS at beta-equilibrium. Both the neutrino-free and neutrino-trapped PNS matters were investigated at different temperature and entropy. The basic properties of PNS like the maximum gravitational mass and radius, the central density, pressure and temperature have been determined at the fixing entropy per baryon and their sensitivity to the nuclear symmetry energy, finite entropy and neutrino trapping are discussed.
