Distinguishing black holes from naked singularities through their accretion disk properties

Joshi, Pankaj S.; Malafarina, D.; Narayan, Ramesh (2014-05-06)

We show that, in principle, a slowly evolving gravitationally collapsing perfect fluid cloud can asymptotically settle to a static spherically symmetric equilibrium configuration with a naked singularity at the center. We ...
Equilibrium configurations from gravitational collapse

Joshi, Pankaj S.; Narayan, Ramesh; Malafarina, D. (2011-11-18)

We develop here a new procedure within Einstein’s theory of gravity to generate equilibrium configurations that result as the final state of gravitational collapse from regular initial conditions. As a simplification, we ...
