Charged cylindrical collapse in f(G) gravity

The aim of this paper is to study the gravitational collapse of charged cylindrical star in f (G) gravity. For this purpose, we derive dynamical equations by applying Misner-Sharp formalism and examine the effects of effective pressure and charge on the collapse rate. We also construct a relationship between matter variables, Gauss-Bonnet (GB) terms, and the Weyl tensor. For the constant value of f (G), it is found that spacetime is conformally flat if and only if the energy density is homogeneous. We conclude that the rate of collapse slows down in f (G) gravity due to anti-gravitational effects.
