Stellar driven processes in (exo)planet atmospheres

The evolution and habitability of (exo)planetary atmospheres is strongly tied 
to the magnetic activity of the host star. In this talk I will explore the 
complex interactions between stellar phenomena and exoplanet atmospheres, 
focusing on how stellar X-ray and UV radiation impact atmospheric escape, 
chemical processes, and thus shape the atmospheres that are observed by 
instruments such as JWST and in the future Ariel and ELT. I will present 
recent and ongoing work from my group, which includes upper atmospheric 
modeling of rocky planets and moons, and observations of stellar magnetic 
activity in the UV.

Characterising exoplanet atmospheres from space-based observations

With the advent of JWST, the characterisation of exoplanet atmospheres from 
spectroscopic observations has entered a new era. Within its first few 
observational cycles, it has already provided us with a large sample of 
varied exoplanet targets, bringing with them new challenges to the methods 
used to characterise the nature of their atmospheres. In my talk, I will 
provide an overview of the observational techniques and methodology used to 
infer the properties of exoplanet atmospheres from spectroscopic 
observations, and present my recent work on assessing atmospheric inference 
methods in the current state-of-the-art provided by JWST.
