Building Robust Models of Planetary Core Dynamics
Orateur : Jonathan Aurnou
Department of Earth, Planetary, and Space Sciences, UCLA
Résumé : The geomagnetic field is powered by turbulent flow in the Earth’s liquid metal outer core. In this seminar, I will first present the essential observations of the geomagnetic field. Then different scenarios will be presented on how best to explain the observations. Lastly, I will evaluate these scenarios based upon our present understanding of rapidly-rotating convective turbulence, and discuss how best to move forward in generating next-generation models of planetary core dynamics.
