Stellar space weather effects on potentially habitable planets

Stellar space weather effects on potentially habitable planets by A. A. Vidotto. on Tuesday 29 November 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. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.15396v1
