| dc.description.abstract | In this paper, we analyze 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 under expansion-free condition. The perturbation scheme is applied to all matter, metric and f (T ) functions. We formulate dynamical equations using contracted Bianchi identities to investigate dynamical instability ranges in Newtonian and post-Newtonian regimes. It is found that the instability ranges of expansion-free fluid are independent of adiabatic index but depend on radial density profile, anisotropic pressure and torsion terms. | en_US |
