Query: Proto-Neutron and Neutron Stars   The parity doublet model, containing the SU(2) multiplets including the
baryons identified as the chiral partners of the nucleons is applied to neutron
stars. The maximum mass for the star is calculated for different stages of the
cooling taking into account finite temperature/entropy effect, trapped
neutrinos and fixed baryon number. Rotation effects are also included.
