摘要：

This paper deals with the study of quasi-spherical gravitational collapse in the framework of f(R, T) theory. We will divide geometry of the star into two distinct portions i.e. interior portion and exterior portion. In the interior portion, we consider quasi-spherical Szekeres line element and in the exterior portion we take Vaidya line element. The interior and exterior portions will be glued by using Israel's junction conditions [W. Israel, Il Nuovo Cimento B (1965-1970) 44, 1 (1966); W. Israel, Phys. Lett. A 24, 184 (1967)]. The field equations will be derived in the context of f(R, T) theory for a particular model. Apparent horizons and their time configuration for various desirable cases will also be discussed.
