Abstract
We consider a modified gravity theory, f(R) = R + Rn − μ4
Rm ,
in the metric formulation and analyze the contribution of electromag-
netic field on the range of dynamical instability of a star filled with
anisotropic matter. The collapse equation is developed by applying
conservation on anisotropic matter, Maxwell source and dark source
terms arising due to f(R) gravity. Specific perturbation scheme is
implemented and it is observed that the inclusion of Maxwell source
slows down the collapse and makes system more stable in Newtonian
regime. Also, we make comparison of our results with the existing
literature.
