Modeling anisotropic magnetized strange quark stars

TL;DR

This paper investigates how strong magnetic fields induce anisotropy in strange quark stars, affecting their size and shape, by comparing models using an axially symmetric metric with traditional TOV equations.

Contribution

It introduces a model incorporating anisotropic effects of magnetic fields on strange quark stars using an axially symmetric metric, extending beyond standard TOV approaches.

Findings

Anisotropy significantly alters star size and shape.

Differences observed between axially symmetric and TOV models.

Magnetic field effects are crucial for accurate modeling.

Abstract

Compact objects have an intrinsic anisotropy due to the presence of strong magnetic fields that cause considerable modifications on the equations of state (EoS). In this work, we study the impact of this anisotropy in the size and shape of magnetized strange quark stars using an axially symmetric metric in spherical coordinates, the gamma-metric. The results are compared with those obtained with the standard Tolman-Oppenheimer-Volkoff (TOV) equations for the parallel and perpendicular pressures independently. Differences in the results are discussed.
