Abstract

V originále

Being inspired by existence of non-equatorial circular (halo) stable orbits of charged particles in composite of gravitational, dipole magnetic and co-rotational electric fields near some planets, we find possible existence of these orbits in strong gravitational fields described by the Kerr?Newman geometry. By using the general relativistic inertial forces formalism combined with the effective potential approach, we show that the stable halo orbits do exist there. But it seems that they are out of theastrophysical importance, being hidden under the inner black-hole horizon, or appearing in the naked singularity spacetimes.
