dc.description.abstractThis work is based on stability analysis of spherically symmetric collapsing star surrounding in locally anisotropic environment in f (R,T ) gravity, where R is Ricci scalar and T corresponds to the trace of energy momentum tensor. Field equations and dynamical equations are presented in the context of f (R,T ) gravity. Perturbation scheme is employed on dynamical equations to find the collapse equation. Furthermore, condition on adiabatic index Γ is constructed for Newtonian and post-Newtonian eras to address instability problem. Some constraints on physical quantities are imposed to maintain stable stellar configuration. The results in this work are in accordance with f (R) gravity for specific case.en_US
