Information about funding sources that supported the collection of the data: NASA Grant 80NSSC20K1269 P00002 7. Overview of the data (abstract): We present first results from a new numerical model to describe the propagation of these Alfvén waves in the Io-Jupiter system. The model is cast in magnetic dipole coordinates and includes a dense plasma torus that is centered around the centrifugal equator. Results are presented for two density models, showing the dependence of the interaction on the magnetospheric density. The effect of the conductance of Jupiter’s ionosphere is considered. A model for the development of parallel electric fields is introduced, indicating that the main auroral footprints of Io can generated parallel potentials of up to 100 kV. -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.
