AI 中文摘要
年轻的 M 型恒星频繁出现耀斑，这会严重影响其宜居行星。由于无法分辨恒星表面，耀斑位置未知。本文利用郭守敬望远镜（LAMOST）光谱中的 Mg I b 发射线，将一颗年轻 M 矮星的恒星耀斑位置精确到极地地区的角度为$ (-123.0^{+8.0}_{-5.8}, 80.5^{+2.9}_{-3.2})$。该方法可精确确定恒星耀斑位置，有助于更准确评估恒星耀斑对行星的影响，增进对恒星发电机模型的理解。
英文摘要
Young M-type stars exhibit frequent flares, which would seriously impact their habitable planets. Since stellar surfaces cannot be resolved, flare locations remain unknown. Here, by using the Mg I b emission line in LAMOST spectra, the location of a stellar flare from a young M dwarf is pinpointed at $ (-123.0^{+8.0}_{-5.8}, 80.5^{+2.9}_{-3.2})$ in degree in the polar region. Our method can be used to accurately locate stellar flares. This would enable us to assess the impact of stellar flares on planets more accurately and improve our understanding of stellar dynamo models.
