Athena X-ray Advances series: webinar by Katja Poppenhaeger

The next webinar of the “Athena X-ray Advances: Science Webinars” is forseen on the 3rd of September at 15 CEST. Katja Poppenhaeger (Leibniz Institute for Astrophysics Potsdam) will give the webinar entitled: Mysteries of exoplanets and low-mass stars and how to shed new X-ray light on them. 

Abstract: Every low-mass star in the Milky Way can be expected to host at least one exoplanet on average. Since most stars are intrinsic X-ray emitters, practically every exoplanet known today is embedded in an X-ray radiation environment of some sort. Stellar high-energy emission can drive many phenomena on exoplanets: heating and evaporation of planetary atmospheres,  photoionization in the upper atmosphere layers, and even direct consequences for planetary habitability. However, it is not only the stars that can influence their exoplanets; there is also growing evidence that exoplanets may influence their host stars through tidal and magnetic interaction. 

High-energy observations are a crucial component in the search for signatures of star-planet interactions. In this talk, I will review current results and present exciting prospects for future X-ray observations.
