Wormhole accretion onto a black hole

Abstract

In this paper, the process of wormhole accretion onto a black hole is studied. We adopt the thin-shell wormhole for the wormhole model, as well as spherical collapse around the black hole and outer axial accretion for the accretion process model. The critical distance of wormhole breaking was roughly estimated by balancing the black-hole tidal force and the force caused by the wormhole tension. © 2012 The Korean Physical Society.
