Abstract:
The astrophysical and observational consequences of the (possible)
existence of Kerr naked singularities (NSs) are examined, and the
circular geodesic orbits in the equatorial plane of a rotating NS are
studied. It is shown that, owing to the existence of negative-energy
orbits, the extraction of rotational energy from these NSs is
astrophysically plausible for both the dissipative processes (by
gravitational radiation or by viscous heating of accretion disks) and
the Penrose process. In addition, the motion of the shell of incoherent
matter in the field of a rotating NS is investigated; the shell,
initially spherical, is found to become prolate along the symmetry axis
during the fall, and to be oblate when the shell returns to infinity.
