Distribution of kilohertz QPO frequencies and their ratios in the atoll source 4U 1636-53
Gabriel Torok, Marek A. Abramowicz, Pavel Bakala +5
A recently published study on long term evolution of the frequencies of the kilohertz quasi-periodic oscillations (QPOs) in the atoll source 4U 1636-53 concluded that there is no p…
On the origin of clustering of frequency ratios in the atoll source 4U 1636-53
Gabriel Torok, Michal Bursa, Jiri Horak +4
A long discussion has been devoted to the issue of clustering of the kHz QPO frequency ratios in the neutron star sources. While the distribution of ratios inferred from an occurre…
Cylinder Buckling: The Mountain Pass as an Organizing Center
Jiri Horak, Gabriel J. Lord, Mark A. Peletier
We revisit the classical problem of the buckling of a long thin axially compressed cylindrical shell. By examining the energy landscape of the perfect cylinder we deduce an estimat…
Parametric resonance as a model for QPO sources -- I. A general approach to multiple scales
J. Horak
In the resonance model, high-frequency quasi-periodic oscillations (QPOs) are supposed to be a consequence of nonlinear resonance between modes of oscillations occurring within the…
