论文摘要
恒星活性可以以辐射(例如增强的X射线冠状发射,耀斑)和颗粒(例如风,冠状质量弹出)的形式展现出来。这些现象共同影响了(EXO)行星周围的空间天气。随着恒星的发展,它们的不同形式的活性也是如此 - 一般而言,年轻的太阳能恒星的风较强,耀斑的发生增强,并且可能更频繁地冠状质量弹出。总的来说,这些效果可以与地球相比,特别是年轻人,为可居住区的行星创造更严格的粒子和辐射环境。在本文中,我将回顾这些更苛刻的环境对潜在可居住的系外行星的一些影响。
Stellar activity can reveal itself in the form of radiation (eg, enhanced X-ray coronal emission, flares) and particles (eg, winds, coronal mass ejections). Together, these phenomena shape the space weather around (exo)planets. As stars evolve, so do their different forms of activity -- in general, younger solar-like stars have stronger winds, enhanced flare occurrence and likely more frequent coronal mass ejections. Altogether, these effects can create harsher particle and radiation environments for habitable-zone planets, in comparison to Earth, in particular at young ages. In this article, I will review some effects of these harsher environments on potentially habitable exoplanets.
