Properties of Magnetized Quark-Hybrid Stars

TL;DR

This paper models magnetized quark-hybrid stars using relativistic mean-field and bag model equations of state, analyzing their mass-radius relations, redshift, and rotation periods in comparison to neutron stars.

Contribution

It introduces a combined modeling approach for magnetized quark-hybrid stars incorporating magnetic field effects into the EoS, and compares their properties with neutron stars.

Findings

Magnetized quark-hybrid stars have distinct mass-radius relationships.

Magnetic fields influence gravitational redshift and rotation periods.

Results differ from standard neutron star models.

Abstract

The structure of a magnetized quark-hybrid stars (QHS) is modeled using a standard relativistic mean-field equation of state (EoS) for the description of hadronic matter. For quark matter we consider a bag model EoS which is modified perturbatively to account for the presence of a uniform magnetic field. The mass-radius (M-R) relationship, gravitational redshift and rotational Kepler periods of such stars are compared with those of standard neutron stars (NS).
