AI 中文摘要
开普勒(Kepler)和凌星系外行星巡天卫星(TESS)等空间测光任务已揭示出恒星耀斑的空前统计数据,包括频繁探测到高能量的超级耀斑。然而,耀斑尤其是超级耀斑的光谱表征仍未普及。与宽带测光不同,光谱数据可提供更多关于耀斑物理参数的信息,还能识别可能伴随的日冕物质抛射(CME)。在此背景下,我们于2022至2023年间,利用PLATOSpec联盟运营的ESO 1.52米望远镜,对年轻的拥有行星的耀星AU Mic进行了约60个部分夜晚(超过160小时)的光谱监测。本文报告了在这些数据中搜寻耀斑和CME信号的结果,包括对一次可能的极端超级耀斑的部分观测。
英文摘要
Photometric space missions like Kepler and TESS have revealed unprecedented statistics of stellar flares, including the frequent detection of highly energetic superflares. Spectroscopic characterization of flares and especially superflares, however, is still not as commonly available. In contrast to broad-band photometry, spectroscopic data can give more insights into the physical parameters of flares, as well as allowing to identify possibly accompanying CMEs. In this context, we monitored the young planet-hosting flare star AU Mic for about 60 partial nights (>160 hours) between 2022 and 2023 spectroscopically with the ESO 1.52m telescope hosted by the PLATOSpec consortium. Here, we report on the search for signatures of flares and CMEs in these data, including the partial observation of a possible extreme superflare.
