英文摘要Using archival rossi x-ray timing explorer (rxte) data, we studied the low-frequency quasi-periodic oscillations (lfqpos) in the neutron star low-mass x-ray binary (lmxb) cir x-1 and examined their contribution to frequency-frequency correlations for z sources. we also studied the orbital phase effects on the lfqpo properties and found them to be phase independent. comparing lfqpo frequencies in different classes of lmxbs, we found that systems that show both z and atoll states form a common track with atoll/bh sources in the so-called wk correlation, while persistent z systems are offset by a factor of about two. we found that neither source luminosity nor mass accretion rate is related to the shift of persistent z systems. we discuss the possibility of a misidentification of fundamental frequency for horizontal branch oscillations from persistent z systems and interpreted the oscillations in terms of models based on relativistic precession.
