Exoplanetary Atmospheres

Understand

The study of exoplanetary atmospheres is one of the most exciting and dynamic frontiers in astronomy.

• Over the past two decades ongoing surveys have revealed an astonishing diversity in the planetary masses, radii, temperatures, orbital parameters, and host stellar properties of exoplanetary systems.
• We are now moving into an era where we can begin to address fundamental questions concerning the diversity of exoplanetary compositions, atmospheric and interior processes, and formation histories, just as have been pursued for solar system planets over the past century.
• Exoplanetary atmospheres provide a direct means to address these questions via their observable spectral signatures.
