摘要
This paper reports on the investigations regarding the possible formation of compact stars in f (R, T) theory of gravity, where R is the Ricci scalar and T is the trace of the energy-momentum tensor. In this connection, we use the analytic solution of the Krori and Barua metric (Krori and Barua in J. Phys. A., Math. Gen. 8: 508, 1975) for a spherically symmetric anisotropic star in the context of f (R, T) gravity. The masses and radii of compact star models, namely Model 1, Model 2, and Model 3, are employed to incorporate the unknown constants in the Krori and Barua metric. The physical features such as regularity at the center, the anisotropy measure, causality, and the well-behaved condition of the above-mentioned class of compact starts are analyzed. Moreover, we also discuss the energy conditions, stability, and surface redshift in f (R, T) gravity.
