摘要
This paper analyzes the effects of charge on the nature of relativistic compact star candidates with anisotropic distribution in the framework of f(R, T) gravity. For this purpose, we consider Krori-Barua solutions and obtain the values of unknown constants as well as charge using observational data of Her X-1, 4U1820-30 and SAX J 1808.4-3658 star models. For three viable f(R, T) models, we investigate the behavior of energy density, transverse as well as radial pressures in the interior geometry of these stars. The validity of energy conditions, effect of anisotropic factor and stability of these stellar models are also examined. We conclude that the effect of charge leads to more stable structures of relativistic compact objects.
