Properties of relativistic star in 5-D Einstein-Gauss-Bonnet gravity

Abstract

In recent years, there has been a growing interest in stellar modelling in the framework of Einstein-Gauss-Bonnet gravity. In this paper, for a relativistic star in static equilibrium, we invoke the $5$ dimensional Einstein-Gauss-Bonnet gravity and solve the system by assuming a matter distribution that admits a linear equation of state (EOS). We fix the model parameters by matching the interior solution to the exterior Boulware-Deser metric which facilitates physical analysis of the resultant configuration. We analyze the star's gross physical properties, which brings to attention the role of the Gauss-Bonnet coupling parameter $\alpha$ in fine-tuning the values of the matter variables.
