Title: Characterising the Atmospheres and Circumplanetary Environment of 
Exoplanets

Abstract:
Since the discovery of the first planet outside our solar-system almost 
25 years ago, the field of exoplanet research has made a lot of 
progress. Not only has the number of known exoplanets increased to over 
3000, the atmospheres for a number of exoplanets have been detected. 
These atmospheric studies have mainly been made for transiting planets. 
For these planets is not only possible to study their atmosphere in 
emission/reflection during the secondary eclipse and through their 
phase-curve, but also in transmission during the transit. I will show 
that ground-based telescopes can be used to reach the high precision 
required to detect the atmospheric signatures, while long-term 
monitoring with space-based telescopes allows us to start and probe 
dynamics in the atmospheres of alien worlds. Finally, I will show how we 
can use high-resolution spectroscopy to search for rings around exoplanets.
