Equations of State of Dense Matter for Astrophysical Simulations

In this web site are equation of state (EOS) tables for dense nuclear matter giving pressure and other properties as a function of density, temperature, and proton fraction. These can be used for astrophysical simulations of core collapse supernovae, black hole formation, and neutron star mergers. These EOS tables are based on relativistic mean field calculations at intermediate and high densities along with Virial and nuclear statistical equilibrium calculations at low densities.

The first EOS based on the NL3 interaction is available.

A PRELIMINARY EOS version based on the FSU gold interaction is now available. PLEASE note this version is still preliminary.
