Charged stellar spheres admitting conformal motion in f(ℛ,𝒜) gravity

This research is conducted within the framework of modified [Formula: see text] gravity, a theoretical extension that incorporates the Ricci scalar [Formula: see text] along with the anti-curvature scalar [Formula: see text]. The considered gravitational model is expressed in a linear form as [Formula: see text], where [Formula: see text] represents the coupling parameter. The study explores novel aspects of the internal structure of a charged compact star under the assumption of a one-parameter group of conformal motion. To determine the free parameters necessary for physical analysis, we employed the matching conditions for a spherically symmetric spacetime with Bardeen’s model, which is taken as the exterior solution. Additionally, a modified form of the Tolman–Oppenheimer–Volkoff equation is derived to examine the equilibrium conditions. The analysis of energy density, pressure profiles, energy conditions, the equation of state parameter, adiabatic index, and the behavior of various forces reveals results that are physically viable and consistent with expected astrophysical properties.
