Detection of propadiene (CHCCH), propene (CH) and non-detection of propane (CH) in Jupiter's northern polar stratosphere

James A. Sinclair, Thomas K. Greathouse, Rohini S. Giles +8

We report the first detection of stratospheric propadiene (CHCCH) and propene (CH) at Jupiter's mid-to-high northern latitudes using IRTF-TEXES measurements recorde…

Constraining Electron-Impact Ionization of O Through UV Aurora Observations at Ganymede

Stefan Duling, Joachim Saur, Darrell Strobel +3

While photoionization rates of Ganymede's O dominated atmosphere are well constrained, the contribution of electron-impact ionization is rather uncertain. Previous quantitative…

Characterising injection signatures in Jupiter's ultraviolet aurora using Juno observations

Linus Head, Denis Grodent, Bertrand Bonfond +12

Discrete features in Jupiter's ultraviolet aurora have been interpreted as signatures of plasma injections in the middle magnetosphere. There exists some ambiguity whether magnetod…

The Polar Stratosphere of Jupiter

Vincent Hue, Thibault Cavalié, James A. Sinclair +13

Observations of the Jovian upper atmosphere at high latitudes in the UV, IR and mm/sub-mm all indicate that the chemical distributions and thermal structure are broadly influenced…
