PT(GRDF2-DD2) cold NS
Abstract
This hadronic EoS table for cold neutron star matter in beta-equilibrium is calculated with a generalized relativistic density functional (GRDF2) based on a relativistic mean-field model of nuclear matter with density dependent nucleon-meson couplings using the functional dependence introduced in [TW_1999] and the parametrization DD2 [TRKBP_2010]. The dissolution of clusters and nuclei is described with medium-dependent mass shifts as defined in [PT_2017]. Phase transitions, e.g., between lattices of different nuclei in the crust or the crust-core transition, are taken into account with Maxwell constructions.See [T_2018,TRKBP_2010,PT_2017,TWRB_2014 ] for details of the EoS model. Besides nucleons, electrons and muons with experimental masses, photons and nuclei are included as degrees of freedom. Masses of nuclei are taken from the 2016 Atomic mass evaluation [WGKH_2016] if available. For other nuclei the predictions of the DZ31 model [DZ_1995] are used.
