Thin-shell wormholes in f(R)-gravity coupled with nonlinear electrodynamics

Abstract

We study the possibility of constructing thin-shell wormhole (TSW) in a particular fR-gravity model with nonconstant Ricci scalar and coupled minimally with nonlinear electromagnetic fields. In doing so, first we give a new static spherically symmetric solution of the theory. Then we apply the cut-and-paste method to construct the TSW. As f ''' R not equal 0 we use the specific junction conditions to match the two spacetimes. We find the exact equilibrium radius of the shell from non-black hole solution and show that a linear perturbation leaves the TSW stable.
