Abstract:
Sources of protons in the Jovian magnetosphere could be from the interaction of solar wind, out-gassing from the icy moons and escape from Jupiter’s ionosphere. We attempt to quantify the relative importance of these different sources by exploring the spatial distribution of density and temperature of protons in the magnetosphere. Through reanalysis of Voyager 1 and 2 Plasma Science (PLS) data obtained between 5 and 30 RJ we produce temperature and density profiles of protons in those regions. Combining these profiles for protons with those of heavy ions (under the assumption of anisotropic Maxwellian distributions) we extrapolate along the field to create global maps of proton density and temperature.
