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 ^ { \circ } 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 \approx 45 ^ { \circ } , we find no significant difference in chaos at the higher 2009 incident angle .
