A study of anisotropic compact star with MIT bag EoS in f(R,T) modified
  theory
  In the current study, we investigated a specific model of anisotropic strange
stars specially Her X-1, in the background of modified f(R,T) gravity by
choosing f(R,T) = R+2{\xi}T, where R is Ricci scalar, T is the trace of the
energy-momentum tensor and {\xi} is a coupling constant. To obtained the
solution for the modified field equations, we apply Buchdahl metric to our
equations. We consider the case, when the matter is governed by MIT bag model
equation of state as Pr =1/3({\rho} -4B), where B is bag constant. We calculate
the values of unknown parameters using Schwarzschild interior space-time
followed by choosing the appropriate values of parameter {\xi} , K, {\beta} and
also tabulated different values of bag constant for different {\xi} . We
examine the physical validity of our model by performing tests such as energy
conditions, equilibrium of the forces, the adiabatic index, redshift and some
more. The observational results showed that the proposed f(R,T) model satisfies
all these tests and are quite acceptable.
