Description
The evolutionary history of exoplanetary atmospheres is inextricably linked to the activity of their host stars. High-energy stellar irradiation (XUV) and magnetic forces drive complex Star-Planet Interactions (SPI), profoundly altering atmospheric chemistry and driving atmospheric escape. In this talk, we explore these dynamic interactions. We will discuss how the combined effects of stellar activity and cloud coverage impact transmission spectra, highlighting the critical implications for atmospheric characterization with next-generation space missions like Ariel.
