Simulations of flux variability of oscillating accretion fluid tori around Kerr black holes
Pavel Bakala, Kateřina Goluchová, Eva Šrámková +4
High frequency quasi-periodic oscillations (HF QPOs) are observed in the X-ray power-density spectra (PDS) of several microquasars and low mass X-ray binaries. Many proposed QPO mo…
Super-spinning compact objects and models of high-frequency quasi-periodic oscillations observed in Galactic microquasars
Andrea Kotrlova, Gabriel Torok, Eva Sramkova +1
We have previously applied several models of high-frequency quasi-periodic oscillations (HF QPOs) to estimate the spin of the central Kerr black hole in the three Galactic microqua…
Mass-angular-momentum relations implied by models of twin peak quasi-periodic oscillations
Gabriel Torok, Pavel Bakala, Eva Sramkova +3
Twin peak quasi-periodic oscillations (QPOs) appear in the X-ray power-density spectra of several accreting low-mass neutron star (NS) binaries. Observations of the peculiar Z-sour…
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…
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…
