LOW-FREQUENCY OSCILLATIONS IN XTE J1550โ564
We present the results of a timing analysis of the low-frequency quasi-periodic oscillation (QPO) in the Rossi X-Ray Timing Explorer data of the black hole binary XTE J1550โ564 during its 1998 outburst. The QPO frequency is observed to vary on timescales between โผ100 s and days, correlated with the count โฆ
