  We have investigated the 2009 July impact event on Jupiter using the ZEUS-MP
2 three-dimensional hydrodynamics code. We studied the impact itself and the
following plume development. Eight impactors were considered: 0.5 km and 1 km
porous (\rho = 1.760 g cm^{-3}) and non-porous (\rho = 2.700 g cm^{-3}) basalt
impactors, and 0.5 km and 1 km porous (\rho = 0.600 g cm^{-3}) and non-porous
\rho = 0.917 g cm^{-3}) ice impactors. The simulations consisted of these
bolides colliding with Jupiter at an incident angle of \theta = 69 degrees from
the vertical and with an impact velocity of v = 61.4 km s^{-1}. Our simulations
show the development of relatively larger, faster plumes created after impacts
involving 1 km diameter bodies. Comparing simulations of the 2009 event with
simulations of the Shoemaker-Levy 9 events reveals a difference in plume
development, with the higher incident angle of the 2009 impact leading to a
shallower terminal depth and a smaller and slower plume. We also studied the
amount of dynamical chaos present in the simulations conducted at the 2009
incident angle. Compared to the chaos of the SL9 simulations, where \theta is
approximately 45 degrees, we find no significant difference in chaos at the
higher 2009 incident angle.
