摘要

Black hole X-ray binary (BHXRB) spends its lifetime in the quiescent state with the dim radiation. It will be luminous when being triggered to be in the outburst, due to the instability in the accretion flow. Timing and spectral properties of its radiation have revealed the blackbody emission from the cold disk and the Comptonized emission from the hot corona. However, the evolution of the disk-corona flow is still not clear during the outburst. In this talk, I will firstly review the timing (e.g., quasi-periodic-oscillation [QPO] and time-lag) and spectral properties of the X-ray radiation. Then, I will introduce our recent studies on (i) QPO spectral-timing behaviors and (ii) the spectral evolution. These studies will help us better understand the evolution of the accretion process in the outburst of BHXRB, in terms of geometry and dynamic.
