O existenci haló orbit v Kerrových-Newmanových prostoročasech
Kovář, J. ; Stuchlík, Z. ; Karas, Vladimír
We discuss existence of halo orbits in Kerr–Newman spacetimes.
Záblesky ze spirálních vln ovlivněné efektem čočkování a časového zpoždění?
Karas, Vladimír ; Dovčiak, Michal ; Eckart, A. ; Meyer, L.
We examine physics of flares from spiral waves by lensing and time-delay amplification.
Změna primárního a reprocesovaného záření v modelu záblesků a skvrn
Dovčiak, Michal ; Karas, Vladimír ; Matt, G. ; Goosmann, René
We study variation of the primary and reprocessed radiation in the flare-spot model.
Orbity hvězd v gravitačním poli hmotného toru v blízkosti centra galaxie
Šubr, L. ; Karas, Vladimír
We further examine orbits of satellite stars in the gravitational field of a dark supermassive compact body, which is surrounded by a self-gravitating accretion disc or a massive molecular torus.
Sestupující orbity v okolí rotující černé díry
Pecháček, T. ; Karas, Vladimír
We consider orbits of a test body near a rotating black hole. The orbits are perturbed by two effects which drive them away from purely geodesic motion.
Obecné souvislosti nelineární resonance 3:2 v kontextu QPO
Horák, Jiří
In the resonant model, quasi periodic oscillations (QPOs) are supposed to be consequence of a nonlinear resonance between modes of oscillations within innermost parts of an accretion disk.
Model pro XSPEC ke zkoumání spekter z černoděrových zdrojů
Dovčiak, Michal ; Karas, Vladimír ; Martocchia, A. ; Matt, G. ; Yaqoob, T.
We report on a new general relativistic computational model enhancing, in various respects, the capability of presently available tools for fitting spectra of X-ray sources.
Proměnnost akreujících zdrojů při vysokém časovém rozlišení
Bursa, Michal
We are carrying out a project to study rapid variability of radiation originating from accreting compact objects. Our goal is to examine fluctuations of the radiation flux occuring on the light-crossing time scales, taking into account effects of strong gravitational field.
Formation of eccentric disks around black holes
Hadrava, Petr ; Řezáč, R. ; Oestgaard, E.
The formation and evolution of eccentric disks around black holes due to explosion of a companion on an eccetric orbit is modeled by means of exact general-relativistic N-particle treatment. It is shown that in spite of the generally accepted view that the debris must be quickly smeared out to a circular accretion disk.
