PT(GRDF2-DD2) new version
Abstract
This general puropose hadronic EoS table 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]. Two-nucleon correlations in the continuum are considered as effective resonances with medium dependent properties [VT_2012].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.The table entries give the properties of the ’local’ EoS, i.e., the results of the density functional for the given temperature, density and charge fraction, without a phase transition construction.
