Magnetized Neutron Star

TL;DR

This paper investigates the effects of strong, axisymmetric poloidal magnetic fields on neutron star structure using a fully general-relativity approach with the LORENE code, revealing deformation and mass increase.

Contribution

It introduces a non-uniform magnetic field profile based on baryon density into neutron star modeling within a general-relativity framework.

Findings

Strong magnetic fields cause neutron star deformation.

Magnetic fields lead to an increase in neutron star mass.

The study uses a realistic magnetic field profile.

Abstract

Our main goal in this work is to study magnetized neutron stars by using a fully general$-$relativity approach presented in the LORENE package\footnote{http://www.lorene.obspm.fr}. Here we have adopted a non-uniform magnetic field profile which depends on the baryon density. This profile has been used in many previous works and seems to be a good choice to explore maximum effects of the internal magnetic field in these objects. Equally important, the magnetic field treated here is poloidal and axisymmetric. The preliminary results show that stars endowed with a strong magnetic field will be deformed and the mass somewhat increased.
