| « Test bodies and naked singularities: is the self-force the cosmic censor? » |
|
E. Barausse |
| Jacobson and Sotiriou recently showed that rotating black holes could be spun-up past the extremal limit by the capture of non-spinning test bodies, if one neglects radiative and self-force effects. This would represent a violation of the Cosmic Censorship Conjecture in four-dimensional, asymptotically flat spacetimes. We show that for some of the trajectories giving rise to naked singularities, radiative effects can indeed be neglected. However, for these orbits the conservative self-force is important, and seems to have the right sign to prevent the formation of naked singularities. |
