Planetary Satellites in Context: Io and the Jovian System

In the past decade, our understanding of the extent and diversity of geological activity in the solar system has undergone a tremendous expansion. Geologically-active satellites provide unique laboratories for studying fundamental planetary processes such as internal heating, thermal & compositional evolution, and volatile loss. New and upcoming telescope facilities are now enabling unprecedented investigations into the surfaces and atmospheres of these bodies, as well as the role they play in populating planetary magnetospheres. Io’s volcanism, and its interactions with the jovian environment, are dramatic examples of these processes. This talk will focus on recent multi-wavelength observations that have shed light on Io’s tidal heating and large-scale effusive volcanism, including its impact on the greater jovian system, and will discuss how ongoing studies are contributing to a framework for understanding individual worlds within the context of their host systems.

Professor Katherine de Kleer is an Assistant Professor of Planetary Science at Caltech. Her research aims to unravel the connections between the atmospheres, surfaces, and interiors of planets and moons to understand their diversity and the processes that shape them. Her work utilizes innovative telescope techniques at optical through radio wavelengths, and has covered a broad range of topics including the atmospheric composition and global circulation of Uranus, Neptune, and Jupiter; the atmospheres and thermal surface properties of the four galilean satellites; and the volcanism and tidal heating of Io. She received her PhD in Astrophysics from UC Berkeley in 2017, and Bachelors degrees in mathematics and physics from MIT.
