PCGS(PCSB1)
Abstract
Equation of state for cold neutron star matter in β-equilibrium containing nucleons, electrons, and muons derived using the relativistic mean field approximation. The description of the Lagrangian density and the EoS model can be found at [PCGS_2022, HTZCS_2018]. The EoS model ‘PCSB1’ results after setting ζ = 0.01 in the RMF Langrangian density given in [PCGS_2022] (i.e., keeping the vector self-interaction strength non-zero and finite, see therein). For the crust, we have attached the crust from [HSNP_2010 ] below a baryon density(nb) < 0.069 fm−3 such that the EoS satisfies the required conditions for thermodynamic stability. The composition data is available for the core EoS only.
