AB: We present results from a 3D global magnetohydrodynamic (MHD) simulation of the magnetosphere of Jupiter with the goal of understanding how features of the magnetosphere relate to either the presence of Iogenic mass, to the rotation of the magnetosphere, to solar wind variations or a combination of these drivers. Using the model we will perform idealized simulations that allow us to isolate the features of the magnetosphere and the drivers that affect them. In addition, we have recently conducted a series of simulations to look at the dawn-dusk asymmetries of the current sheet thickness as observed by Galileo. These studies indicate that Jupiter's magnetic field responds dynamically to the stretching in the tail and the quasi-periodic release of plasmoids down the tail. We will explore the simulation results as they relate to both magnetospheric configuration and dynamics.
