GMSR(H7)
Abstract
This table corresponds to the unified EoS of cold catalized nuclear matter at β-equilibrium by G. Grams, J. Margueron, R. Somosundaram and S. Reddy [GMSR_2021]. The crust is model with a compressible liquid drop model (CLDM) with Coulomb, surface and curvature terms, the crust model is named finite size 4 (FS4). The considered effective interaction is given by the non-relativistic (NR) meta-model (MM) adjusted to reproduce the Chiral EFT Hamilatonian H7. The lowest order nuclear empirical parameters (E, L / n, K ) are defined from a fit of symmetric matter (SM) and neutron matter (NM) to the original model, while the higher order ones (K', Z) are fixed to reach a 2Msun neutron star. See Ref. [GMSR_2021].
