论文摘要
在过去的十年中，在太空和地面监测功能方面都有很大的增长，在（罕见的）短暂性事件中，BH X射线二进制文件的覆盖率更高。此间隔包括有史以来观察到的三个最亮X射线爆发中的两个，即2015年的V404 CYG和2018年的Maxi J1820+070，以及Swift J1357.2-0933的爆发，这是第一个此类系统，用于显示可变时期的第一个系统。现在，这些爆发的极端多波长档案，包括光度法和光谱镜，它们以喷气式和圆盘风的形式显示出大量的流出，以及X射线光谱/时机揭示了内部积聚盘的演变。对Maxi J1820+070事件的基于地面的AAVSO光学监测是有史以来最广泛的事件，揭示了随着其状态过渡的变化而演变的周期性变化。这些调制是从未见过的幅度，并提出了通过过渡持续存在的辐射驱动的圆盘经线的发展。所有这些结果都证明了所有时间尺度上广泛的多波长光度和光谱监测的力量。
The last decade has seen a significant gain in both space and ground-based monitoring capabilities, producing vastly better coverage of BH X-ray binaries during their (rare) transient events. This interval included two of the three brightest X-ray outbursts ever observed, namely V404 Cyg in 2015, and MAXI J1820+070 in 2018, as well as the outburst of Swift J1357.2-0933, the first such system to show variable period optical dipping. There are now superb multi-wavelength archives of these outbursts, both photometric and spectroscopic, that show substantial outflows in the form of jets and disc winds, and X-ray spectroscopy/timing that reveals how the inner accretion disc evolves. The ground-based AAVSO optical monitoring of the MAXI J1820+070 event was the most extensive ever obtained, revealing periodic variations that evolved as it approached its state transition. These modulations were of an amplitude never seen before, and suggested the development of an irradiation-driven disc warp that persisted through the transition. All these results have demonstrated the power of extensive multi-wavelength photometric and spectroscopic monitoring on all time-scales.
