Thin-shell wormholes with a generalized Chaplygin gas in Einstein-Born-Infeld theory

Abstract

We construct spherically symmetric thin-shell wormholes supported by a generalized Chaplygin gas in Born-Infeld electrodynamics coupled to Einstein gravity, and we analyze their stability under radial perturbations. For different values of the Born-Infeld parameter and the charge, we compare the results with those obtained in a previous work for Maxwell electrodynamics. The stability region in the parameter space reduces and then disappears as the value of the Born-Infeld parameter is modified in the sense of a larger departure from Maxwell theory. © 2012 Springer-Verlag Berlin Heidelberg and Società Italiana di Fisica.
