The `Ups' and `Downs' of a Spinning Black Hole | | Chris M. Chambers

2 Oct 1997 | | Subject: | gr-qc | | Affiliation: | Montana State University | | Abstract: | We report and comment upon the principal results of an investigation into the evolution of rotating black holes emitting massless scalar radiation via the Hawking process. It is demonstrated that a Kerr black hole evaporating by the emission of scalar radiation will evolve towards a state with $a approx 0.555M$. If the initial specific angular momentum is larger than this value the hole will spin down to this value; if it is less it will spin up to this value. The addition of higher spin fields to the picture strongly suggests the final asymptotic state of a realistic evaporation process will be characterized by an $a/M = 0$. | | Source: | arXiv, gr-qc/9710013 | | Services: | Forum | Review | PDF | Favorites | |
