论文摘要
2019年，银河中心黑洞SGR A*产生了异常数量的明亮近红外耀斑，包括有史以来最明亮的耀斑（Do等，2019年，重力协作2020年）。我们建议该活动是由G1和G2物体与背景积聚流相互作用的几乎同时同时插入的材料中的材料触发的。我们讨论了S-Star和G-Object脱离材料的机制，并估算到达黑洞的材料数量和插入时间。
In 2019, the Galactic center black hole Sgr A* produced an unusually high number of bright near-infrared flares, including the brightest-ever detected flare (Do et al 2019, Gravity Collaboration 2020). We propose that this activity was triggered by the near simultaneous infall of material shed by G1 and G2 objects due to their interaction with the background accretion flow. We discuss mechanisms by which S-stars and G-objects shed material, and estimate both the quantity of material and the infall time to reach the black hole.
