摘要

This paper presents a picture of compact structures for the f(R,T) model of the form R+γ eχT,with γ and χ being parameters.The polytropic equation of state and the MIT bag model reflect the pressure density relation for these compact objects.For this purpose,a system of two differential equations involving pressure as well as the mass of the stellar structure is obtained from field equations and the Tolman-Oppenheimer-Volkoff (TOV) equation.The numerical solution of this system gives a graphical description of various characteristics of these compact systems.To examine the viability and stability of assumed configurations,the energy conditions,causality relation and adiabatic index are discussed for the presumed scenario.
