eng Abstract:
[eng][cze] We further investigate the issue of kHz QPO frequency ratios in neutron star low mass X-ray binaries. In this note we report on recent analysis of occurrences and properties of kHz QPOs in the source 4U1636-53. Assuming that kHz QPOs occur in pairs whose frequencies are linearly correlated, we find a prominent frequency range that separates upper and lower QPO observations.Na základě analýzy dat QPO frekvencí zdroje 4U1636-53 a pěti dalších zdrojů ukazujeme, že páry QPO jsou detekovány zejména v okolí přechodových bodů, kde se mění některé vlastnosti QPO, zejména amplituda a koherence QPO.
