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…
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…
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…
