Abstract:
Charged fluids circling in strong central gravitational and ambinet
magnetic fields, characteristic for compact objects backgrounds, can
embody interesting configurations. In contrast to the widely considered
neutral fluid structures imitating thick equatorial accretion discs with
negligible loss of mass, when the fluid is properly charged, we can find
it forming unique toroidal structures `levitating‘ above the equatorial
plane and also those hovering near the symmetry axis. Along with
analytical topological studies of these structures, we can also present
an survey of their basic physical characteristics, such as pressure,
density and temperature profiles.
