Description
A large sample of equation of state (EOS) models built within a Bayesian inference is used to investigate the thermal behavior of homogeneous matter with Brussels extended Skyrme interactions over wide ranges of density and temperature, in both symmetric nuclear matter and pure neutron matter. Our key finding is that, via a lower limit on the effective mass, the condition imposed on neutron Fermi velocity not to exceed the speed of light leads to negative values of thermal pressure, previously predicted by $\chi$-ETF calculations.
Tables of general purpose EOS models, suitable to input in astrophysical simulations, are being produced are made available for the community. We expect that, once implemented in numerical simulations of binary neutron star mergers or core-collapse simulations, these EOS tables will lead to evolutions qualitatively different than those obtained based on traditional Skyrme interactions.
