(Exo)Planetary Atmospheres and Evolution
(Exo)Planetary Atmospheres and Evolution
Session ID#: 159356
Session Description:
Understanding the nature and variability of (exo)planetary atmospheres, their chemical evolution and the physical mechanisms governing atmospheric dynamics are strong driving forces of (exo)planetary science and solar system exploration mission planning. While the long-term Earth evolution is constrained by geological studies and isotopic analyses, the evolutionary paths of other planets must be reconstructed from data obtained through astronomical observations and planetary missions. We are on the eve of being able to characterize exoplanetary atmospheres, thanks to the James Webb Space Telescope and its future successors. At the same time, better understanding of the Solar system terrestrial planets is at hand with incoming missions to Venus. Models of planetary atmospheres use these observations to illuminate physical processes operating, from the Earth to planets in our Solar system and beyond. Processes that govern the interactions of atmospheres with planetary surfaces and interiors are an important aspect of planetary evolution, for both atmosphere composition and thermal state (including surface conditions). The rapidly increasing number of discovered exoplanets provides an exciting opportunity for interdisciplinary collaborations, between heliophysicists, astrophysicists, planetary and climate scientists. This session welcomes observational, theoretical, experimental, and field studies relevant to physical and chemical evolution of (exo)planetary atmospheres and planetary habitability in and outside of our solar system.
