Magnetotail Dipolarizations at Mercury: Lessons from a Miniature Magnetosphere 

Ryan Dewey, 

University of Michigan 



Abstract: Dipolarizations in Earth’s magnetotail play a major role in plasma and magnetic flux transport, particle heating and acceleration, and substorm current wedge formation. Mercury, whose magnetosphere closely resembles Earth’s topologically, also experiences dipolarizations despite Mercury’s shorter spatiotemporal scales and lack of an ionosphere. In light of these magnetospheric differences, we investigate the nature of dipolarizations at Mercury using MESSENGER spacecraft observations. We discuss how differences between the magnetospheres influence dipolarization dynamics and how the implications of our results may shape our understanding of the substorm process at terrestrial planets.
