Abstract:
We investigate possible signatures of a Kerr naked singularity
(superspinar) in the profiled spectral lines of radiation emitted by
monochromatically and isotropically radiating point sources forming a
Keplerian ring or disc around such compact object. We have found out
that the profiled spectral line of the radiating Keplerian ring can be
splitted into two parts due to the fact that there is no event horizon
in the naked singularity spacetimes.
