Abstract
We study the dynamical instability of a spherically symmetric collapsing star in the context of f (T) gravity. For this purpose, we assume power-law f (T) model with non-dissipative anisotropic fluid distribution and find the dynamical equations which are used to construct collapse equation. The perturbation scheme is applied to all matter, metric and f (T) functions. We formulate the collapse equation under perturbation to investigate dynamical instability ranges in Newtonian as well as post-Newtonian regimes. It is found that these ranges depend on structural quantities of the collapsing star through adiabatic index. Finally, we develop some constraints on positivity of these quantities to meet the dynamical instability condition.
