• # Abstract

In the present work, we have searched for the existence of anisotropic and non-singular compact star in the $f (R, T)$ gravity by taking into account the non-exotic equation of state (EoS). In order to obtain the solutions of the matter content of the compact object, we assume the well-known barotropic form of EoS that yields the linear relation between pressures and energy density. We propose the existence of non-exotic compact star which shows the validation of energy conditions and stability within the perspective of $f (R,T)$ extended theory of gravity. The linear material correction in the extended theory and matter content of compact star can remarkably satisfy energy condition. We discuss various physical features of the compact star and show that the proposed model of the stellar object satisﬁes all regularity conditions and is stable as well as singularity-free.
