MESSENGER observations of Mercury's planetary ion escape rates and their dependence on true anomaly angle

Weijie Sun, Ryan M. Dewey, Xianzhe Jia +11

This study investigates the escape of Mercury's sodium-group ions (Na+-group, including ions with m/q from 21 to 30 amu/e) and their dependence on true anomaly angle (TAA), i.e., M…
