Hot neutron stars with microscopic equations of state

We study the properties of hot beta-stable nuclear matter using equations of state derived within the Brueckner-Hartree-Fock approach at finite temperature including consistent three-body forces. Simple and accurate parametrizations of the finite-temperature equations of state are provided. The adiabatic index is analyzed in some detail. The properties of hot neutron stars are then investigated within this framework, in particular, the temperature dependence of the maximum mass. We find very small temperature effects and analyze the interplay of the different contributions.
