SPG(M1) Crust NS EoS
Abstract
This inner crust EoS for β-equilibrium matter at zero temperature is con- structed with a BSk22 outer crust [ PCP_2018] below n_B = 2 × 10^−3 fm^−3 , an inner crust EoS calculated within a Compressible Liquid Drop approach [2] up to n_B = 0.74 × 10^−1 fm^−3 . The EoS parameterisation used was one of the density-dependent RMF models with the GDFM functional for the couplings [ GDFM_2008] generated in a Bayesian analysis and that agrees with both astrophysical and nuclear constraints [ SPG_2024].
