摘要：
This paper explores the anisotropic stellar configurations governed by polytopic equation of state in f(R, T) theory (where R denotes the Ricci scalar and T is the trace of energy-momentum tensor). For this purpose, we numerically solve the system of differential equations obtained from the field equations and hydrostatic equilibrium equation. We investigate physical characteristics of polytropic stars and examine their stability using both causality condition as well as the adiabatic index. It is concluded that stellar configurations are stable and the value of mass function lies within the Chandrasekhar limit.
