Abstract
In this article, a known anisotropic solution named Tolman-Finch-Skea (TFS) is discussed under gravitational decoupling (GD) approach in the framework of $4$-dimensional Einstein-Gauss-Bonnet (EGB) gravity. The radial metric potential is linearly transformed with the minimal geometric deformation (MGD) approach while the temporal metric part remains unchanged. The system of EGB field equations converted into two distinct systems of field equations, where one of them is against the standard energy-momentum-tensor (EMT), while the other one is related to the external gravitational source. The first system is determined by using aforementioned known solution, while the second one is closed by using mimic constraint on pressure. Moreover, the junction conditions at the inner and outer surfaces of stellar object are examined with Boulware-Deser 4D space--time as the outer geometry. The stellar model is physically analyzed by using the parameters like energy conditions, causality condition, Herrera's cracking condition, compactness and red shift.
