Web28 mrt. 2013 · Planetary auroral emissions are an observable signature of the coupling between the planetary magnetosphere and ionosphere. Jovian and Saturnian auroral emissions are created by a variety of processes, including those driven by the orbital motions of moons through the planetary magnetic plasma, the local creation, and … WebThe effect of the conductance of Jupiter’s ionosphere is considered, showing that a long auroral footprint tail is favored by high Pedersen conductance in the ionosphere. The current patterns in these cases show a U-shaped footprint due to the generation of field-aligned current on the Jupiter-facing and Jupiter-opposed sides of Io, which may ...
