Stellar matter with a strong magnetic field within density-dependent relativistic models

TL;DR

This paper investigates how strong magnetic fields influence the equation of state and crust properties of compact stars within density-dependent relativistic models, highlighting differences from other mean-field models especially at low densities.

Contribution

It introduces a detailed analysis of magnetic field effects on the EoS in density-dependent relativistic models and compares these effects with other mean-field approaches.

Findings

Magnetic fields significantly alter the crust extension of stars.

Largest model differences occur at low densities.

Magnetic effects are crucial for understanding star crust properties.

Abstract

The effect of strong magnetic fields on the equation of state (EoS) for compact stars described with density-dependent relativistic hadronic models is studied. A comparison with other mean-field relativistic models is done. It is shown that the largest differences between models occur for low densities, and that the magnetic field affects the crust properties of a star, namely its extension.
