Jupiter's X-ray and EUV auroras monitored by Chandra, XMM-Newton, and Hisaki satellite

Hasegawa, H.; Fujimoto, M.; Masters, A. +17 more

Jupiter's X-ray auroral emission in the polar cap region results from particles which have undergone strong field-aligned acceleration into the ionosphere. The origin of precipitating ions and electrons and the time variability in the X-ray emission are essential to uncover the driving mechanism for the high-energy acceleration. The magnetospheric…

Modeling the magnetospheric X-ray emission from solar wind charge exchange with verification from XMM-Newton observations

Palmroth, Minna; Milan, Steve E.; Carter, Jennifer A. +3 more

An MHD-based model of terrestrial solar wind charge exchange (SWCX) is created and compared to 19 case study observations in the 0.5-0.7 keV emission band taken from the European Photon Imaging Cameras on board XMM-Newton. This model incorporates the Global Unified Magnetosphere-Ionosphere Coupling Simulation-4 MHD code and produces an X-ray emiss…
