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.
