The response of Jupiter's magnetosphere to an outburst on Io

A 6-month-long monitoring campaign of the lo plasma torus and neutral cloud was conducted to determine the characteristics of their interaction. During the observations, a large outburst of material from lo-inferred to be caused by the eruption of a volcanic plume on lo-caused a transient increase in the neutral cloud and plasma torus masses. The response of the plasma torus to this outburst shows that the interaction between to and Jupiter's magnetosphere is stabilized by a feedback mechanism in which increases in the plasma torus mass cause a nonlinear increase in loss from the plasma torus, limiting plasma buildup.
