摘要:

We present high time‐resolution multicolour observations of the quiescent soft X‐ray transients V404 Cyg and XTE J1118+480 obtained with ULTRACAM. The power density spectrum (PDS) of the V404 Cyg data shows a quasi‐periodic oscillation (QPO) feature at 0.78 mHz (=21.5 min), whereas the PDS of the XTE J1118+480 data shows a break. We discuss the possible origins for the QPO feature and break‐frequency in the context of the advection‐dominated accretion flow model. © 2004 American Institute of Physics
