Charged compact star model in Einstein-Maxwell-Gauss-Bonnet gravity

Abstract

Present paper provides a model of static charged anisotropic fluid sphere in the EinsteinMaxwell- GaussBonnet (EMGB) theory of gravitation. We select KB anstz as the metric co-efficient along with electric field intensity. To develop our model we assume a linear EoS between the radial pressure and the matter density. The model obtained here is found to satisfy the elementary physical requirements like non-negativity nature of pressure and density, the energy conditions, continuity of the metric co-efficients, subliminal velocity of sound and also pressure free hypersurface etc. It may also noted that the solution is free from any kind of singularities.
