The magnetosphere of Jupiter harbors the most extreme radiation belts in the solar system. Studying and understanding them is not only important for space physics and planetary science, but also crucial to predict the radiation hazard for artificial satellites.
This seminar will present what is known and unknown on the radiation belts of Jupiter thanks to in-situ measurements (Pioneer, Voyager, Galileo, Juno), remote sensing (UV diffuse aurora, X-Ray emissions, synchrotron signal at radio wavelength), and modeling (empirical and physics-based). We will highlight that the biggest science questions on the Jovian radiation belts will remain open even after JUICE and Europa-Clipper. We will therefore advocate for the COMPASS mission, a "Van Allen probe at Jupiter" concept developed for the NASA-NSF Heliophysics decadal survey. Finally, we will showcase that Jupiter is the best analogue for extrasolar radiation belts, which have been recently imaged around a brown dwarf.
