We have simulated the entry of cometary nuclei into Jupiter (Korycansky et al. 2006 ApJ 646. 642-652) and now extend our 3D hydrodynamic models to plume formation and blowout. We investigate the physics that control plume behavior, including why and where plumes "pinch off", separating from the descending cometary remains, and what determines how much cometary material is in a plume. We also examine the effects of impactor size, composition, velocity, and impact angle, and the corresponding changes in visible and infrared observations, with application to the Shoemaker-Levy 9, 2009, and 2010 Jovian impacts.
We adapted the ZEUS-MP/2 hydrodynamic model (Hayes et al. 2006 ApJ.SS. 165. 188-228), using a grid aligned and moving with the impactor and containing a tilted Jovian atmosphere. The grid is large enough to contain both the impact and blowout phases to avoid the need for ad hoc initial conditions. We present details on the ejection mechanism, velocity and mass distribution within the plume, and the shock waves generated by the expanding plume.
