Preliminary EoS for core-collapse supernova simulations with the QMC model

Abstract

In this work we present the preliminary results of a complete equation of state (EoS) for core-collapse supernova simulations. We treat uniform matter made of nucleons using the the quark-meson coupling (QMC) model. We show a table with a variety of thermodynamic quantities, which covers the proton fraction range $Y_p=0-0.65$ with the linear grid spacing $\Delta Y_p=0.01$ ($66$ points) and the density range ${\rho }_B=10^{14}-10^{16}$g.cm${}^{-3}$ with the logarithmic grid spacing $\Delta lo{g}_{10}({\rho }_B/[$g.cm${}^{-3}])=0.1$ ($21$ points). This preliminary study is performed at zero temperature and our results are compared with the widely used EoS already available in the literature.
