摘要: Quasi-periodic oscillations (QPO) have been observed during the past decade in flux of many bright X-ray sources on time scales from ∼103 sec to milliseconds. This area research attracted lots attention 1984 when intensity-dependent QPO were found GX 5–1 frequency range ∼20–35 Hz (Van der Klis et al. 1985). Since then, a lot observational and theoretical work has done. Various forms identified, picture is beginning evolve.
