TSO(DDLS(30)-Y)
Abstract
This general-purpose EoS table considers hypernuclear matter. The tables are extracted from a model that is based on covariant density functional (CDF) theory with a variable slope of symmetry energy Lsym and skewness Qsat parameterisation [ LS_2023 ] that includes the full JP = 1/2+ baryon octet in a manner that is consistent with current astrophysical constraints. The present table employs super-saturation CDF with fixed Lsym = 30 MeV and Qsat = 400 MeV [ TSO_2024 ]. A NSE model [HSNP_2010 ] based on the DD2 parameterisation [TRKBP_2010 ] is attached for the low-density inhomogeneous EoS.
