Abstract:
We study the properties of axisymmetric and stationary toroidal
structures of magnetized perfect fluid with the uniform distribution of
specific angular momentum (l = const) orbiting Kerr superspinars whose
existence is indicated by string theory. We demonstrate first the
specific features of unmagnetized perfect fluid tori occurring in the
deep potential well near the surface of the superspinars and enabling
clear distinction between Kerr superspinars and Kerr black holes. Then,
we investigate the effect of magnetization of the perfect fluid tori and
describe the shift of their properties induced by the presence of
toroidal magnetic fields.
