# Relativistic strange quark stars in Lovelock gravity

## TL;DR

This paper investigates how the Gauss-Bonnet term in Lovelock gravity affects the structure and properties of relativistic strange quark stars in five-dimensional spacetime, using numerical solutions of modified TOV equations.

## Contribution

It introduces a study of strange quark stars within Lovelock gravity, analyzing the impact of the Gauss-Bonnet term on stellar properties in five dimensions.

## Key findings

- Gauss-Bonnet parameter influences star mass and radius.
- Mass-to-radius profiles vary with different Gauss-Bonnet values.
- Maximum star mass and radius are affected by the Gauss-Bonnet term.

## Abstract

We study relativistic non-rotating stars in the framework of Lovelock gravity. In particular, we consider the Gauss-Bonnet term in a five-dimensional spacetime, and we investigate the impact of the Gauss-Bonnet parameter on properties of the stars, both isotropic and anisotropic. For matter inside the star, we assume a relativistic gas of de-confined massless quarks. We integrate the modified Tolman-Oppenheimer-Volkoff equations numerically, and we obtain the mass-to-radius profile, the compactness of the star as well as the gravitational red-shift for several values of the Gauss-Bonnet parameter. The maximum star mass and radius are also reported.
