Csaba Palotai and Joe Harrington, along with the graduate and undergraduate students of the Jovian Impact Research Group, investigate the various stages of asteroidal and cometary impacts in Jupiter’s atmosphere.
To do so, our group is building the first self-consistent, 3D computer model of all phases of the events, from initial impact to dissipation of the material. The results will provide insight into planetary atmospheric physics, including the first direct measurement of eddy viscosity. The results will also be relevant to the study and mitigation of potential future terrestrial impacts. From these events, information about the frequency of impacts, Jupiter’s atmosphere, and impact processes has been uncovered. To analyze these events, we use computer simulations of the object in question penetrating the Jovian atmosphere.
