Abstract:
We summarize influence of the tidal charge parameter of the braneworld
models onto some optical phenomena in rotating black hole spacetimes.
The shape of an equatorial thin accretion disk and profiled spectral
lines of thin keplerian rings around the black holes are given and
classified in terms of the black hole rotational and tidal parameters.
It is shown that rising of negatively-valued tidal parameter, with
rotational parameter fixed, generally strengthens the relativistic
effects and suppresses the rotation induced asymmetries in the optical
phenomena.
