Investigating planetary atmospheres in our own Solar System and beyond: Advances and Perspectives — •Miriam Rengel — Max-Planck-Institut für Sonnensystemforschung

The exploration of planets inside and outside our own Solar System is a very active research area in astronomy and planetology, and exoplanets are known to exhibit an extreme diversity in their physical properties. Investigating the chemical composition of planets helps to constrain atmospheric processes, abundances, and formation and evolution conditions. Crossing the next frontier in detailed characterization of exoplanetary atmospheres via remote-sensing, which is dependent on observations and interpretation toolkits, it is instructive to start with an assessment of the atmospheric characterization of planets and satellites in our own Solar System. In this contribution, I will concentrate on the investigation of key atmospheric gases and thermal profiles on Venus and Titan. Although these atmospheres have been studied with a variety of remote-sensing techniques, across a wide spectral range, they are still not fully understood. With the help of spectroscopic observations and appropriate radiative transfer calculations and atmospheric retrieval methods, I constrain the chemical concentration profiles, temperature and winds in these fascinating atmospheres.

Furthermore, expanding our knowledge gained from studies of solar system planets, I will review the latest key achievements accomplished in the study of exoplanet atmospheres, developments in our understanding of physical and chemical conditions of planetary atmospheres, and prospects for the future.
