摘要：

This paper deals with the theoretical modeling of anisotropic compact stars in the framework of f (T) theory of gravity, where T is torsion scalar. To this end, we have used the exact solutions of Krori and Barua metric to a static spherically symmetric metric. The unknown constants involved in the Krori and Barua metric have been specified by using the masses and radii of compact stars 4U1820-30, Her X-1, SAX J 1808-3658. The physical properties of these stars have been analyzed in the framework of f (T) theory. In this setting, we have checked the anisotropic behavior, regularity conditions, stability and surface redshift of the compact stars.
