Habitable planet and its host star
SpaceRef
Stellar activity can manifest itself in the form of radiation (eg, enhanced coronal X-ray emission, flares) and particles (eg, winds, coronal mass ejections). Together, these phenomena shape the space climate around (exo)planets.
As stars evolve, so do their different forms of activity: in general, younger Sun-like stars have stronger winds, enhanced flare, and probably more frequent coronal mass ejections.
Together, these effects can create harsher particle and radiation environments for planets in the habitable zone compared to Earth, particularly at young ages. In this article, I will review some effects of these harsher environments on potentially habitable exoplanets.
