HS(DD2) neutron matter (with electrons)
Abstract
This is the zero electron fraction EOS table with RMF interactions DD2 [TRKBP_2010]. Contributions of neutrons, anti-neutrons, protons, anti-protons, electrons, positrons, and photons are included, whereas the net abundances of electrons and protons are always zero. The details of the underlying EOS model at finite Y e can be found in Ref. [HSNP_2010], where the TMA interactions were used. The manual from the web page https://astro.physik.unibas.ch/people/matthias-hempel/equations-of-state.html/ gives further information about the table. Applications of HS EOS for various different RMF interactions in supernova simulations can be found in Refs. [HFSLA_2012,SHF_2013].
