Proto-Neutron and Neutron Stars in a Chiral SU(3) Model

Abstract

A hadronic chiral SU(3) model is applied to neutron and proto-neutron stars, taking into account trapped neutrinos, finite temperature and entropy. The transition to the chirally restored phase is studied and global properties of the stars like minimum and maximum masses and radii are calculated for different cases. In addition, the effects of rotation on neutron star masses are included and the conservation of baryon number and angular momentum determine the maximum frequencies of rotation during the cooling.
