Oscillations of tori in the pseudo-Newtonian potential
Eva Sramkova, Ulf Torkelsson, Marek A. Abramowicz
Context. The high-frequency quasi-periodic oscillations (HF QPOs) in neutron star and stellar-mass black hole X-ray binaries may be the result of a resonance between the radial and…
Epicyclic Oscillations of Fluid Bodies: Newtonian Nonslender Torus
Omer M. Blaes, Eva Sramkova, Marek A. Abramowicz +2
We study epicyclic oscillations of fluid tori around black holes (in the Paczynski-Wiita potential) and derive exact analytic expressions for their radial and vertical eigenfrequen…
QPOs in microquasars: the spin problem
Gabriel Torok, Marek A. Abramowicz, Zdenek Stuchlik +1
In the Galactic microquasars with double peak kHz quasi-periodic oscillations (QPOs), the ratio of the two frequencies is 3:2. This supports the suggestion that double peak kHz QPO…
