Redistribution of Material in Saturn's Magnetosphere via Charge Exchange: Posst Cassini Perspective
Abstract
The interaction of the plasma trapped in Saturn's magnetsophere with hydrogen emitted from Saturn's atmosphere, with molecules in the ring atmosphere and with the atoms and molecules emitted from the icy satellites is now better understood based on Cassini data. Here we review the role of charge exchange during ion-neutral collisions in redistributing atoms and molecules throughout the Saturnian system. Charfe exchange can scatter molecules emitted from the rings and satellites into Saturn's atmosphere and water products from the rings and from Enceladus redistributed throughout the magnetosphere contribute oxygen to Titan's atmosphere. Here we review both the charge exchange database and the Cassini observations, with special emphasis on the neutrals and plasma affecting our understanding of the F-ring orbit data.
