Composition of the Jovian Plasma Disk: Simultaneously Forward Modelling Two Juno JADE Datasets

In this poster we examine the ion composition of the Jovian plasma disk at different radial distances. Maxwellian distributions are assumed, but we also compare the effect of trying Kappa distributions. The plasma disk is known to include protons as well as the heavy ion components of oxygen and sulfur ions of various charge states, with distributions that overlap each other in energy per charge space. The JADE-I TOF dataset has no directional information, but can separate ions by mass per charge (m/q). The JADE-I Species dataset has very limited mass per charge resolution, and fewer counts per look direction, but has directional information. Using forward modelling we simultaneously fit both the directional species dataset and the m/q identifying TOF dataset. This is complicated due to them being fundamentally different data products, on different scales, with different instrument features to account for. However, this has been overcome and forward modelling code has been successfully run. The fitted ions have a shared fitted (3D) velocity, and unlike previous studies, each heavy ion species has its own fitted temperature.
