Description
| - A long discussion has been devoted to the issue of clustering of the kHz quasi periodic oscillation (QPO) frequency ratios in the neutron star sources. While the distribution of ratios inferred from an occurrence of a single QPO seems to be consistent with a random walk, the distribution based on simultaneous detections of both peaks indicates a preference of ratios of small integers. Based on the public RXTE data we further investigate this issue for the source 4U1636-53. Quality factors and rms amplitudes of both the QPOs nearly equal at the points where the frequencies are commensurable, and where the twin QPO detections cluster. We discuss a connection of the clustering with the varying properties of the two QPO modes.

- Za použití pozorování zdroje 4U 1636-53 zkoumáme rozložení poměrů frekvencí kHz QPO. Zdá se, že v místech, kde se seskupují poměry frekvencí pozorovaných párů QPO, dochází i k přechodu v dalších charakteristikách, jako je koherence a amplituda oscilace. (cs)
