Latest results on Jovian disk X-rays from XMM-Newton [PDF]

open access: yes, 2007
We present the results of a spectral study of the soft X-ray emission (0.2–2.5 keV) from low-latitude (‘disk’) regions of Jupiter. The data were obtained during two observing campaigns with XMM-Newton in April and November 2003.
