恒星日冕物质抛射

Stellar Coronal Mass Ejections

Martin Leitzinger, Petra Odert

摘要:

恒星日冕物质抛射(CME)是一个日益发展的研究领域,特别是在过去十年。迄今为止探测到的大量系外行星提出了恒星CME活动的开放性问题,因为CME可能强烈影响系外行星大气。此外,由于日冕物质抛射导致恒星质量和角动量损失,因此与恒星演化有关,因此需要更好地描述这一现象。在这篇文章中,我们回顾了不同的方法使用到现在为止,试图检测恒星CME。我们讨论了不同方法的局限性,并得出结论,这一研究领域的未来可能的前景。

英文摘要:

Stellar coronal mass ejections (CMEs) are a growing research field, especially during the past decade. The large number of so far detected exoplanets raises the open question for the CME activity of stars, as CMEs may strongly affect exoplanetary atmospheres. In addition, as CMEs contribute to stellar mass- and angular momentum loss and are therefore relevant for stellar evolution, there is need for a better characterization of this phenomenon. In this article we review the different methodologies used up to now to attempt the detection of stellar CMEs. We discuss the limitations of the different methodologies and conclude with possible future perspectives of this research field.
