Inner crust equations of state for CompOSE

TL;DR

This paper introduces new relativistic mean-field equations of state for neutron star inner crusts, compatible with experimental constraints and capable of modeling two-solar-mass stars, validated against recent astrophysical observations.

Contribution

The authors provide updated equations of state for the neutron star inner crust that meet multiple constraints and incorporate recent observational data.

Findings

Equations of state reproduce two-solar-mass neutron stars.

Mass-radius relations align with NICER data.

Tidal deformability matches LIGO/Virgo measurements.

Abstract

In this paper, we present some relativistic mean-field inner crust equations of state that have recently been uploaded in the CompOSE online repository. These equations of state fulfill experimental and microscopic constraints, and are also able to reproduce two solar-mass stars. We integrate the TOV equations to obtain the mass-radius relation, and we also calculate the tidal deformability, compactness, and effective tidal deformability to compare with the latest astrophysical data from NICER and LIGO and Virgo.
