Plasma in the Jovian magnetosphere: X-ray+EUV study of aurora & Io plasma torus

We propose 4x40 ks Chandra/HRCI and 2x40 ks XMMNewton observations of theJovian aurora and Io plasma torus in conjunction with the Japanese SPRINTAsatellite. SPRINTA will continuously observe Jupiter from Dec 2013 to Apr 2014,making sensitive EUV spectroscopic observations of the aurora and IPT. We willcorrelate variations in the Xray flux from the aurora and IPT with changes inthe EUV flux observed by SPRINTA and with the properties of the solar wind. Wewill conclusively resolve the puzzle of the origin of the Jovian Xray emissionand determine if the precipitating particles originate from Io or from the solarwind. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
