Journal ArticleDOI
Influence of Cosmic Repulsion and Magnetic Fields on Accretion Disks Rotating around Kerr Black Holes
TL;DR: In this article, the influence of cosmic repulsion and external magnetic fields on accretion disks rotating around rotating black holes and on jets associated with these rotating configurations is discussed. But the authors consider both geometrically thin and thick disks.
Journal ArticleDOI
Transition from Regular to Chaotic Circulation in Magnetized Coronae near Compact Objects
TL;DR: In this paper, the authors investigate the case of a rotating black hole immersed in a weak, asymptotically uniform magnetic field and find that the role of the black hole spin in setting the chaos is more complicated than initially thought.
Journal ArticleDOI
Pseudo-newtonian gravitational potential for schwarzschild–de sitter space–times
Zdeněk Stuchlík,Jiří Kovář +1 more
TL;DR: In this article, a pseudo-Newtonian gravitational potential describing the gravitational field of static and spherically symmetric black holes in the universe with a repulsive cosmological constant is introduced.
Journal ArticleDOI
Pseudo-Newtonian and general relativistic barotropic tori in Schwarzschild–de Sitter spacetimes
TL;DR: In this article, the shape and potential depths of a marginally stable barotropic tori with uniform distribution of specific angular momentum were determined using both the pseudo-Newtonian and fully relativistic approach.
Journal ArticleDOI
Electrically charged matter in rigid rotation around magnetized black hole
TL;DR: In this article, the authors study charged-fluid toroidal structures surrounding a nonrotating charged black hole immersed in a large-scale, asymptotically uniform magnetic field.
