Kinetic formulation of Tolman-Ehrenfest effect: Non-ideal fluids in Schwarzschild and Kerr space-times

Claudio Cremaschini, Jiří Kovář, Zdeněk Stuchlík +1

A review of the original thermodynamic formulation of the Tolman-Ehrenfest effect prescribing the temperature profile of uncharged fluid at thermal equilibrium forming stationary c…

Polytropic representation of the kinetic pressure tensor of non-ideal magnetized fluids in equilibrium toroidal structures

Claudio Cremaschini, Jiří Kovář, Zdeněk Stuchlík +1

Non-ideal fluids are generally subject to the occurrence of non-isotropic pressure tensors, whose determination is fundamental in order to characterize their dynamical and thermody…

Charged fluids encircling compact objects: force representations and conformal geometries

Jiří Kovář, Yasufumi Kojima, Petr Slaný +2

Charged fluids rotating around compact objects can form unique equilibrium structures when ambient large-scale electromagnetic fields combine with strong gravity. Equatorial as wel…

Relativistic and Newtonian fluid tori with electric charge

Vladimir Karas, Ondrej Kopacek, Audrey Trova +3

We discuss the effects of electric charging on the equilibrium configurations of magnetized, rotating fluid tori around black holes of different mass. In the context of gaseous/dus…

Equilibrium configurations of charged fluid around Kerr black hole

A. Trova, K. Schroven, E. Hackmann +3

Equilibrium configurations of electrically charged perfect fluid surrounding a central rotating black hole endowed with a test electric charge and embedded in a large-scale asympto…

Plunging neutron stars as origin of organised magnetic field in galactic nuclei

V. Karas, O. Kopacek, D. Kunneriath +4

Black holes cannot support their own internal magnetic field like, for example, compact stars can. Despite this fact observations indicate that event horizons of supermassive black…
