QHC19-A

Abstract

This table corresponds to the zero temperature and beta-equilibrium unified EoS by Baym et al. [ BFH_2019]. The EoS are divided into three distinct domains: the crust- nuclear liquid, hadron-quark crossover, and quark matter domains. For each domain we assign an equation of state as

Crust- nuclear liquid : Togashi EoS [TNTYST_17]
Crossover : QHC19A [BFH_2019]
Quark matter : QHC19A [BFH_2019]

The quark matter EoS (including up-, down-, and strange-quarks) in the QHC19 was calculated using the NJL model within the mean field approximation. As variable parameters, we choose g_V and H which quantify the strength of the repulsive density-density interaction and the attractive paring-interaction between quarks, respectively. We chose (g_V, H)=(0.60,1.43)G which is compatible with hadron physics. The QHC19A satisfies the empirical constraints from neutron stars as well as the causality and thermodynamic consistency.
