Note on a thin-shell wormhole in extremal Reissner-Nordström geometry
arXiv:1704.04435 · doi:10.1142/S0218271818500281
Abstract
We show that the cold horizon of the extremal Reissner-Nordström can be considered as the throat of a thin-shell wormhole with zero total exotic matter and positive angular pressure. Such a wormhole is physical and stable against radial perturbations provided an appropriate perfect fluid exists at the throat.
