Atmospheres, Climate, and Potential Habitability of Rocky Exoplanets

Session ID#: 158638

Session Description:
Exoplanet discoveries of the past decade have shown that every star hosts at least 0.1-1 roughly Earth-sized, or rocky, planets. Our galaxy therefore contains billions of rocky worlds, vastly outnumbering the 4 rocky planets of our own Solar System. What are these worlds like?   This session invites submissions that probe the nature of rocky exoplanets, including: What can our Solar System teach us about rocky exoplanets? How different are atmospheres and climates on rocky planets around other stars, on rocky planets in exotic orbital states, or on rocky planets with radically different formation histories? How can we characterize such planets via observations? And could the processes that kept Earth habitable over billions of years also occur elsewhere?   Submissions that use observation, experiment, or theory are all welcome.
