Abstract:
In the framework of the brany models, rotating black holes are described
by the Kerr metric with a tidal charge representing the influence of the
non-local gravitational (tidal) effects of the bulk space Weyl tensor
onto the black hole spacetime. Here we study the influence of the tidal
charge onto profiled spectral lines generated by radiating tori orbiting
in vicinity of a rotating black hole. We show that with lowering the
negative tidal charge of the black hole, the profiled line becomes to be
flatter and wider.
