Io is the most volcanically active body in the solar system, and its volcanic plumes rise hundreds of kilometers above the surface. They rise far above the atmosphere, and I model this plume expansion into a near-vacuum with Direct Simulation Monte Carlo. I simulate Pele, one of the largest plumes, in 3D using observations of the caldera to guide my choice of source geometry. My goal is to explain the physics behind the deposition pattern and plume structure seen in observations. I also simulate plumes alongside other features of Io’s environment, like its sublimation atmosphere and Jupiter’s plasma torus, to understand how plumes fit into the big picture.
