Bardeen compact stars in modified [formula omitted] gravity

Abstract

This work aims to study a charged compact star in the scenario of f(R) theory of gravity. We use some matching condition of spherically symmetric space-time with Bardeen’s model as an exterior geometry and examine the physical behaviour of anisotropic parameter, effective radial and tangential pressure component. In the current analysis, we discuss the energy conditions to check the viability of our model. Furthermore, an equilibrium condition can be visualized through the modified Tolman-Oppenheimer-Volkov equation. We investigate the stability of anisotropic sphere through casualty condition and Adiabatic index. We also prefer to use the radial and tangential equation of states parameters. Further, we examine mass-radius function, compactness and surface redshift, which are some essential features of charged compact star. It is worthwhile to mention here for the current study that our stellar structure in the background of Bardeen’s model is more viable and stable.
