论文摘要
即将到来的任务，包括James Webb太空望远镜，很快将在凉爽的K-和M型星周围可居住区域中的地面型外部球星的气氛中描述，以寻找大气生物签名。最近的观察结果表明，活跃的凉爽行星宿主的电离辐射和颗粒环境可能不利于超球门的可居住能力。由于没有有关辐射场的直接信息，因此经常使用恒星活动的特征（包括星形的大小和磁场）之间的经验关系。在这里，我们重新审视星形点大小与有效恒星温度之间的经验关系，并评估其对恒星火光能量，冠状质量弹出和相关恒星能量颗粒事件的量的影响。
Upcoming missions, including the James Webb Space Telescope, will soon characterize the atmospheres of terrestrial-type exoplanets in habitable zones around cool K- and M-type stars searching for atmospheric biosignatures. Recent observations suggest that the ionizing radiation and particle environment from active cool planet hosts may be detrimental for exoplanetary habitability. Since no direct information on the radiation field is available, empirical relations between signatures of stellar activity, including the sizes and magnetic fields of starspots, are often used. Here, we revisit the empirical relation between the starspot size and the effective stellar temperature and evaluate its impact on estimates of stellar flare energies, coronal mass ejections, and fluxes of the associated stellar energetic particle events.
