Planetary Atmospheres, Space Weather, and Magnetic Fields: A Joint AGU-AAS Session

Session ID#: 159712

Session Description:
Atmospheric retention, and how it is influenced by stellar activity (i.e., space weather) and a planet's magnetic field, is a topic of current interest for Solar System and extrasolar planets.  Detailed measurements of atmospheric escape rates and processes from many Solar System planets exist, with the MAVEN mission having provided perhaps the most comprehensive set of measurements regarding erosion of the Martian atmosphere. Comparison of escape rates from Venus, Earth, and Mars has sparked a debate about whether planetary magnetic fields shield planetary atmospheres from erosion or accelerate it.

In an extrasolar planetary context, the Kepler "radius gap" between sub-Neptunes and super-Earths suggests that atmospheric escape can be driven by the interaction between a planet's atmosphere and its host star's space weather. Moreover, both the stellar properties that drive escape and a planet's magnetic field evolve over time.

The Exoplanet Science Strategy, the Pathways to Discovery Decadal Report (Panel on Exoplanets, Astrobiology, and the Solar System), and Priority Science Questions in the Origins, Worlds, and Life Decadal Report all address aspects of planetary magnetic fields and atmospheres.

For the AGU22, we will focus on results and lessons learned from studies of Solar System planets, with an invited presentation to describe relevance to extrasolar planets.  For AAS 241, we will focus on results from extrasolar planets, with an invited presentation to describe how results from Solar System planets provide "ground truth."
