... Related Charged-Particle Acceleration by Jupiter's Satellite IO Gurnett, Donald A. Abstract Several current theories on ... radio emission, and its modulation by the satellite Io, assume that the plasma within the magnetic flux tube passing through Io is "frozen" to the motion of Io. This paper considers the effects of the plasma sheath around Io on the interaction of Io with the Jovian magnetosphere. It is found that ... plasma from the motional electric field generated within Io, thus preventing the plasma from being frozen to ...
