摘要: The aim of this paper is to analyze the nature anisotropic spherically symmetric relativistic star models in framework f(R, T) gravity. To discuss features compact stars, we consider that interior stellar system, fluid distribution influenced by MIT bag model equation state. We construct field equations employing Krori–Barua solutions and obtain values unknown constants with help observational data Her X-1, SAX J 1808.4-3658, RXJ 1856-37 4U1820-30 models. For a viable model, study behavior energy density, transverse as well radial pressure factor these stars for specific value constant. check physical viability our proposed stability structure through conditions, causality condition adiabatic index. It concluded satisfies criteria other requirements, constant agreement experimental which highlights considered model.
