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

preprint2015arXivOpen access

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 Yp=0−0.65Y_{p}=0-0.65 with the linear grid spacing ΔYp=0.01 ΔY_{p}=0.01 (6666 points) and the density range ρB=1014−1016ρ_{B}=10^{14}-10^{16}g.cm−3^{-3} with the logarithmic grid spacing Δlog10(ρB/[Δlog_{10}(ρ_{B}/[g.cm−3])=0.1^{-3}])=0.1 (2121 points). This preliminary study is performed at zero temperature and our results are compared with the widely used EoS already available in the literature.
