摘要

耀斑,有时伴随着日冕物质抛射(CMEs),是恒星磁场突然变化的结果,通过磁重联释放出高能量,可以在从无线电波到光学范围再到 X 射线的广泛电磁波谱范围内观测到。在我们的观测综述中,我们试图收集一些基本的新成果,这些成果在很大程度上与过去二十年空间测光观测的扩展所带来的大数据时代有关。我们列出了显示耀斑活动的不同类型恒星及其观测策略,并讨论了它们的主要恒星特性与它们发射的耀斑(甚至是 CMEs)特性之间的关系。我们的目标是,在不自称完整的前提下,重点关注那些可能以某种方式挑战基于太阳范式的 "标准 "耀斑模型的结果。

Stellar Flares, Superflares, and Coronal Mass Ejections—Entering the Big Data Era
Flares, sometimes accompanied by coronal mass ejections (CMEs), are the result of sudden changes in the magnetic field of stars with high energy release through magnetic reconnection, which can be observed across a wide range of the electromagnetic spectrum from radio waves to the optical range to X-rays. In our observational review, we attempt to collect some fundamental new results, which can largely be linked to the Big Data era that has arrived due to the expansion of space photometric observations over the last two decades. We list the different types of stars showing flare activity and their observation strategies and discuss how their main stellar properties relate to the characteristics of the flares (or even CMEs) they emit. Our goal is to focus, without claiming to be complete, on those results that may, in one way or another, challenge the “standard” flare model based on the solar paradigm.
