Abstract

This paper constitutes the investigations regarding possible formation of compact stars in f(R,T)f(R,T) theory of gravity, where RR is Ricci scalar and TT is trace of energy momentum tensor. In this connection, we use analytic solution of Krori and Barua metric (Krori and Barua 1975)to spherically symmetric anisotropic star in context of f(R,T)f(R,T) gravity. The masses and radii of compact stars models namely model 11, model2 2 and model 33 are employed to incorporate with unknown constants in Krori and Barua metric. The physical features such as regularity at center, anisotropy measure, casuality and well-behaved condition of above mentioned class of compact starts are analyzed. Moreover, we have also discussed energy conditions, stability and surface redshift in f(R,T)f(R,T) gravity.
