This paper explores charged stellar structures whose pressure and density are related through polytropic equation of state (; is polytropic constant, p is pressure, denotes density and is polytropic exponent) in the scenario of gravity (where R is the Ricci scalar and T is the trace of energy-momentum tensor). The Einstein-Maxwell field equations are solved together with the hydrostatic equilibrium equation for where is the coupling constant, also called model parameter. We discuss different features of such configurations (like pressure, mass and charge) using graphical behavior for two values of . It is found that the effects of model parameter on different quantities remain the same for both cases. The energy conditions are satisfied and stellar configurations are stable in each case.
