Gravitational collapse on the brane: a no-go theorem Bruni, Marco Germani, Cristiano Maartens, Roy Col·lapse gravitacional Forats negres (Astronomia) Gravitational collapse Black holes (Astronomy) We investigate how braneworld gravity affects gravitational collapse and black hole formation by studying Oppenheimer-Snyder-like collapse on a Randall-Sundrum-type brane. Without making any assumptions about the bulk, we prove a no-go theorem: the exterior spacetime on the brane cannot be static, which is in stark contrast with general relativity. We also consider the role of Kaluza-Klein energy density in collapse, using a toy model. 2019-05-08T11:37:51Z 2019-05-08T11:37:51Z 2001-11-13 2019-05-08T11:37:51Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.1103/PhysRevLett.87.231302 Physical Review Letters, 2001, vol. 87, num. 23, p. 231302 https://doi.org/10.1103/PhysRevLett.87.231302 (c) American Physical Society, 2001 info:eu-repo/semantics/openAccess American Physical Society Articles publicats en revistes (Institut de Ciències del Cosmos (ICCUB))
