RB(BBSk3)
Abstract
This table contains the EOS by Raduta and Beznogov (RB) [RB_2025 ] computed using the BBSk1 interaction, which belongs to the family of Brussels extended Skyrme inter- actions. BBSk1 was built within a Bayesian investigation of the EOS of dense mat- ter [BR_2024 ]. The model includes nucleons, a distribution of nuclei, photons, electrons and positrons. For densities lower than n_S and temperatures lower than the limiting tem- perature for Coulomb instabilities (T_lim ), the extended nuclear statistical equilibrium (NSE) approach of Ref. [ RB_2025 ]is employed. For T ≥ T_lim and/or n ≥ n_tr , where n_tr is the transition density to homogenous matter, nuclear matter is homogeneous. We consider that T_lim = 2/3T_C , where T_C represents the critical temperature for the liquid-gas phase transition of homogeneous symmetric nuclear matter. The pool of NSE nuclei consists of nuclei present in AME2020 [WHKAN_2021 ] and DZ10 [DZ_1995 ] tables, from where the values of binding energies are taken. The internal partition function is computed using a back-shifted Fermi gas parametrization [EB_2005 ]. The Coulomb interaction between nuclei and electrons and among electrons is estimated within the Wigner-Seitz approximation. Interactions between nuclei and with the unbound nucleons are accounted for within the excluded volume approximation
