Summary
"We develop a new type of a global plasma simulation model with adaptive charged particle kinetic physics for the Mercury-solar wind interaction. Mercury’s solar wind interaction, or space weather, is unique in the solar system due to spatially small and temporally fast magnetospheric scales, airless solid body with a large conducting core, a tenuous surface-originating exosphere and the closest distance to the Sun of the planets. These features mean that Mercury is an ideal ""compact-sized magnetospheric solar wind interaction laboratory"" for spacecraft and model studies compared to Earth's much larger magnetosphere. Since Mercury's plasma environment is populated by a unique composition of exospheric heavy ions mixed with the solar wind, the magnetosphere is much smaller than at Earth and under stronger solar wind conditions, studying Mercury reveals new information on space weather processes in general. The main scientific objectives of the BepiColombo (BC) two-orbiter mission en-route to Mercury include the investigation of the structure and dynamics of the Hermean magnetosphere and exosphere. The new model to be developed in this project is based on high-performance computing and an adaptive algorithm for charged particle kinetic effects. This enables efficiently resolving Hermean space weather processes and the coupled, complex solar wind-magnetosphere-exosphere system at detail beyond current global models. The new model is applied in the interpretation of observations by BC with the focus on the role of charged particle effects in the physics of basic space weather processes."
