Oscillations of radiation pressure supported tori near black holes
Grzegorz P. Mazur, Olindo Zanotti, Aleksander Sądowski +2
We study the dynamics of radiation pressure supported tori around Schwarzschild black holes, focusing on their oscillatory response to an external perturbation. Using KORAL, a gene…
Twin peak HF QPOs as a spectral imprint of dual oscillation modes of accretion tori
Pavel Bakala, Kateřina Goluchová, Gabriel Török +4
High frequency (millisecond) quasi-periodic oscillations (HF QPOs) are observed in the X-ray power-density spectra of several microquasars and low mass X-ray binaries. Two distinct…
Distinguishing between spot and torus models of high-frequency quasiperiodic oscillations
V. Karas, P. Bakala, G. Torok +8
In the context of high-frequency quasi-periodic oscillation (HF QPOs) we further explore the appearance of an observable signal generated by hot spots moving along quasi-elliptic t…
Spectral signature of oscillating slender tori surrounding Kerr black holes
F. H. Vincent, G. P. Mazur, O. Straub +4
Context. Some microquasars exhibit millisecond quasi-periodic oscillations (QPO) that are likely related to phenomena occuring in the immediate vicinity of the central black hole.…
Power density spectra of modes of orbital motion in strongly curved spacetime: obtaining the observable signal
P. Bakala, G. Torok, V. Karas +8
High frequency quasi-periodic oscillations (HF QPOs) appear in the X-ray variability of several accreting low-mass binaries. In a series of works it was suggested that these QPOs m…
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…
