摘要：
In this article we provide a new class of interior solutions of a five-dimensional compact star in Einstein-Gauss-Bonnet (EGB) gravity within the framework of Finch-Skea space-time. The exterior space-time is described by the EGB Schwarzschild solution. To check physical validity of our model we investigate various physical properties like causality of solutions, energy conditions, mass radius relations, Tolman-Oppenheimer-Volkov (TOV) equations, etc.
