[1008.5159] Test bodies and naked singularities: is the self-force the cosmic censor?

Abstract: It has been suggested by Jacobson and Sotiriou that rotating black holes could be spun-up past the extremal limit by the capture of non-spinning test bodies, which would represent a violation of the Cosmic Censorship Conjecture in four-dimensional, asymptotically flat spacetimes. This analysis, however, neglected radiative and self-force effects. Here we show that for some of the trajectories that can give rise to naked singularities, radiative effects can be neglected. However, for these orbits the conservative part of the self-force is important, and can potentially prevent the appearance of naked singularities.
