慧眼卫星对黑洞X射线双星的爆发演化研究

he Insight-HXMT (Insight Hard X-ray Modulation Telescope) satellite has achieved a series of significant scientific breakthroughs during its on-orbit operation, thanks to its unique broadband coverage (1250 keV) and large effective area. By monitoring the outburst evolution of numerous black hole X-ray binaries (BHXBs), Insight-HXMT has provided crucial observational data for investigating accretion processes during these events. These outbursts include not only typical full outbursts, which progress through hard, intermediate, and soft states, but also \failed transition outbursts", where the system remains in the hard or intermediate states without fully transitioning. The broadband capabilities of Insight-HXMT offer a valuable opportunity to gain deeper insights into the properties of the accretion disc, corona, and jet in BHXBs. Furthermore, these observations play a crucial role in advancing our understanding of BHXBs outburst mechanisms and accretion radiation physics. This article focuses on the evolution and characteristics of BHXBs outbursts as revealed by Insight-HXMT data.
