Analysis of charged compact stars in f(R,T) gravity using Bardeen geometry

Abstract

The purpose of this paper is to examine the anisotropic matter distribution concerning one of the well-known [Formula: see text] theories of gravity, where [Formula: see text] and [Formula: see text] represent the Ricci scalar and trace of the energy–momentum tensor, respectively. We consider anisotropic matter distribution in spherically symmetric spacetime for our desired work. We investigate the physical behavior of pressure components, energy density, anisotropic function, equation of state parameters, and energy conditions. Furthermore, we analyze the stability of compact stars by investigating the causality condition, adiabatic index, and generalized Tolman–Oppenheimer–Volkoff equation. Some fundamental features of compact stars have been investigated, like compactness factor, mass function, and surface redshift. Our calculated solutions for Bardeen stellar structures are consistent and stable in the background of the [Formula: see text] theory of gravity.
