A new and more comprehensive model of charge-exchange induced X-ray emission,due to ions precipitating into the Jovian atmosphere near the poles, has beenused to analyze spectral observations made by the Chandra X-ray Observatory.The model includes for the first time carbon ions, in addition to the oxygenand sulfur ions previously considered, in order to account for possible ionorigins from both the solar wind and the Jovian magnetosphere. By comparing themodel spectra with newly reprocessed Chandra observations, we conclude thatcarbon ion emission provides a negligible contribution, suggesting that solarwind ions are not responsible for the observed polar X-rays. In addition,results of the model fits to observations support the previously estimatedseeding kinetic energies of the precipitating ions (~0.7-2 MeV/u), but infer adifferent relative sulfur to oxygen abundance ratio for these Chandraobservations.
