#AthenaNuggets: Extrasolar planets: a radiation diet
In the #AthenaNuggets 40, Jorge Sanz talks about the relationship between the emission of X-rays by a star and its exoplanets. The role of X-rays is fundamental to understand the phenomena of erosion in exoplanet's atmospheres.
The sensitivity of Athena will improve our knowledge of X-ray emission of exoplanet host stars, providing us with more reliable coronal models.
