Abstract:
We test possible observational consequences of presence of Kerr
superspinars indicated by string theories. We demonstrate that such
superspinars could survive up to the era of high redshift quasars. We
demonstrate unusual properties of disc oscillations of Kerr superspinars
and variety of unusual optical phenomena related to accretion discs
orbiting them.
