Multilayer neutron stars with scalar mesons crossing term

TL;DR

This paper demonstrates that a recent relativistic mean field model with sigma and delta meson interactions accurately describes neutron star observations and reveals a phase transition in the outer core of neutron stars.

Contribution

It introduces a RMF model with sigma and delta meson interactions that aligns with observational data and uncovers a phase transition in neutron star cores.

Findings

Model agrees with observational data

Identifies a phase transition in neutron star outer core

Reveals complex multilayer structure in neutron stars

Abstract

It is shown that recently proposed RMF model with $\sigma$ and $\delta$ meson interaction agrees with the observational data and presents an interesting structure with phase transition in the outer part of neutron star core.
