Characterizing Exoplanets’ Atmospheres to Unveil Planetary Origins and Climate

Presenter: Jean-Michel DESERT
The study of exoplanet atmospheres is the next step in leveraging exoplanetary detections. This is because a planet’s atmosphere provides a fossil record of its primordial origins and controls its fate, size, appearance, and ultimately its habitability. In this context, I present comparative exoplanetology programs that aim at characterising planetary systems transiting nearby stars through the observations of their atmospheres. Our findings on the atmospheric composition and physical properties provide insights into the formation and evolution of planetary systems and enhance our understanding of our own Solar System’s formation.
