摘要:

在过去的十年里,空间和地面监测能力都有了显著的提高,在BH X射线双星(罕见的)瞬态事件期间,对它们的覆盖率大大提高。这个间隔包括有史以来观测到的三次最明亮的X射线爆发中的两次,即2015年的V404 Cyg和2018年的MAXI J1820+070,以及Swift J1357.2-0933的爆发,这是第一个显示可变周期光学倾斜的系统。现在,这些爆发的出色多波长档案(包括光度和光谱)显示了喷流和盘风形式的大量外流,以及揭示内部吸积盘如何演变的X射线光谱/计时。对MAXI J1820+070事件的地面AAVSO光学监测是有史以来最广泛的,揭示了在接近其状态转换时演变的周期性变化。这些调制的幅度是以前从未见过的,并建议通过过渡持续辐射驱动光盘翘曲的发展。所有这些结果都证明了在所有时间尺度上广泛的多波长光度和光谱监测的能力。

英文摘要:

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.
