Nuclear Matter Density

The nuclear matter density at finite temperature was evaluated analytically in the relativistic mean field theory using Sommerfeld approximation at low temperature. These analytical results are interesting since they allow a more transparent analysis of the contributions of the involved parameters.

We investigate the properties of mixed stars formed by hadronic and quark matter in β-equilibrium described by appropriate equations of state (EOS) in the framework of relativistic mean-field theory. The calculations were performed for T=0 and for finite temperatures and also for fixed entropies with and without neutrino trapping in order to describe neutron and proto-neutron stars. The star properties are discussed. Maximum allowed masses for proto-neutron stars are much larger when neutrino trapping is imposed.

Supernova Collapse

Nuclear matter incompressibility is calculated in the framework of the relativistic mean field theory. Asymmetry reduces the incompressibility. The isothermal incompressibility decreases with increasing temperature, and the isentropic one decreases with increasing entropy. Attention is given to the incompressibility at supernova collapse conditions.
