Rel. Mean Field and Virial EOS based on the NL3 interaction

The format of these equation of state tables is described in a readme.pdf file

The full equation of state table including baryon, photon, and lepton contributions is in a gzip compressed ~100 MB file NL3eos1.03.dat.gz

The baryon only EOS table without photon and lepton contributions is NL3eosb1.03.dat.gz

readeos.f is a sample fortran file to read the above tables.

The current version of this EOS is 1.03 (as of March, 2011).

Here are short notes regarding updates to the equation of state table. References include: “Equation of state of nuclear matter in a viril expansion of nucleons and nuclei”, G. Shen, C. J. Horowitz, S. Teige, Phys. Rev. C 82, 045802 (2010). “Equation of State of Dense Matter from a density dependent relativistic mean field model”, G. Shen, C. J. Horowitz, S. Teige, Phys. Rev. C 82, 015806 (2010).

NL3eos1.03, 3/8/2011
Corrects error in proton chemical potential at very small proton fraction

Eos1.02, 10/27/2010
Corrects errors in neutron and proton chemical potentials at a small number of low temperature points.

Eos1.01, 10/9/2010
Gives more accurate pressure at low densities.

Eos1.0, 9/22/2010
Smoothes pressure and entropy as a function of density to give better adiabatic index and removes oscillations in sound speed. Now on 40 points per decade grid.

Eos_80, 7/30/2010
Original version of EOS table on 80 points per decade grid.

Older versions of the EOS, that you probably don't want to use unless you have a particular reason, are available here.
