Multi-resonance orbital model applied to high-frequency quasi-periodic oscillations observed in Sgr A*
Andrea Kotrlova, Zdenek Stuchlik, Gabriel Torok
The multi-resonance orbital model of high-frequency quasi-periodic oscillations (HF QPOs) enables precise determination of the black hole dimensionless spin a if observed set of os…
Kinetic theory of equilibrium axisymmetric collisionless plasmas in off-equatorial tori around compact objects
Claudio Cremaschini, Jiří Kovář, Petr Slaný +2
The possible occurrence of equilibrium off-equatorial tori in the gravitational and electromagnetic fields of astrophysical compact objects has been recently proved based on non-id…
Multi-resonance orbital model of high-frequency quasi-periodic oscillations: possible high-precision determination of black hole and neutron star spin
Zdenek Stuchlik, Andrea Kotrlova, Gabriel Torok
Using known frequencies of the twin-peak high-frequency quasiperiodic oscillations (HF QPOs) and known mass of the central black hole, the black-hole dimensionless spin can be dete…
Towards modeling quasi-periodic oscillations of microquasars with oscillating slender tori
G. P. Mazur, F. H. Vincent, M. Johansson +4
Context. One of the often discussed models for X-ray binaries high-frequency quasi-periodic oscillations is the oscillating torus model that considers oscillation modes of slender…
Charged tori in spherical gravitational and dipolar magnetic fields
P. Slany, J. Kovar, Z. Stuchlik +1
A Newtonian model of non-conductive, charged, perfect fluid tori orbiting in combined spherical gravitational and dipolar magnetic fields is presented and stationary, axisymmetric…
Resonant switch model of twin peak HF QPOs applied to the source 4U 1636-53
Zdenek Stuchlik, Andrea Kotrlova, Gabriel Torok
Resonant Switch (RS) model of twin peak high-frequency quasi-periodic oscillations (HF QPOs) assumes switch of twin oscillations at a resonant point where frequencies of the upper…
