Abstract:
We consider equatorial motion of test particles around a rotating Kerr naked singularity in the Randall-Sundrum braneworld scenario and its implications for the properties of Keplerian accretion disks. We demonstrate existence of some unexpected phenomena related to properties of spacetimes having positive braneworld tidal charges. This new phenomenon can be an interesting explanation for extremely high energy cosmic radiation.
