Bardeen compact stars in modified <b>f(R)</b> gravity with conformal motion

The main emphasis of this paper is to find the viable solutions Einstein Maxwell fields equations compact star in context modified $f(R)$ theory gravity. Two different models gravity are considered. In particular, we choose isotropic matter distribution and Bardeen's model for boundary conditions as an exterior space-time geometry. We use conformal Killing geometry compute metric potentials. discuss behavior energy density pressure both models. Moreover, analyze physical properties such pressure, equilibrium conditions, equation state parameters, causality adiabatic index. It noticed that suitable provides results with Bardeen
