Topographic effects in planetary fluid cores: application to the Earth-Moon system
Understanding planetary core flows is crucial as they generate planetary magnetic fields and modify planetary rotation. However, their study is an outstanding challenge involving geomagnetism, geodesy and fluid mechanics. Notably, present models fail to explain two puzzling observations. First, geodesy constrains the Earth and Moon core dissipations to values exceeding those of current theoretical models. Second, lunar paleomagnetism gives an early Moon magnetic field too intense for the current planetary dynamo paradigm, based on convection. My project tackles these issues by going beyond the present planetary core simulations, performed in exact spheres. Planetary core boundaries are…
