An updated view of Jupiter's UV main auroral emission: large-scale analysis of UV and particle data from Juno's first 60 orbits
Linus Head, Denis Grodent, Bertrand Bonfond +9
The properties and origins of Jupiter's UV main auroral emission are, at present, not yet fully understood, particularly the extent to which its two distinct zones, the Zone-I and…
The Ultraviolet Spectrograph on ESA's Jupiter Icy Moons Explorer Mission (JUICE-UVS)
Kurt D. Retherford, Philippa M. Molyneux, Thomas K. Greathouse +51
The Jupiter Icy Moons Explorer (JUICE) mission, led by ESA, has an Ultraviolet Spectrograph (JUICE-UVS) contributed by NASA and built at Southwest Research Institute. JUICE-UVS is…
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…
Investigating Magnetic Field Fluctuations in Jovian Auroral Electron Beams
A. Salveter, J. Saur, G. Clark +4
The Juno spacecraft provides a unique opportunity to explore the mechanisms generating Jupiter's aurorae. Past analyses of Juno data immensely advanced our understanding of its aur…
Jupiter's UV auroral response to a magnetospheric compression event
R. S. Giles, T. K. Greathouse, R. W. Ebert +12
The highly elliptical polar orbit of the Juno mission provides a unique opportunity to simultaneously measure the compression state of Jupiter's magnetosphere and the total power e…
Jupiter's ultraviolet auroral bridge: the influence of the solar wind on polar auroral morphology
L. A. Head, D. Grodent, B. Bonfond +9
Jupiters ultraviolet aurora frequently shows a number of arcs between the dusk-side polar region and the main emission, which are denoted as bridges. This work presents a largely a…
Effect of magnetospheric conditions on the morphology of Jupiter's UV main auroral emission, as observed by Juno-UVS
L. A. Head, D. Grodent, B. Bonfond +9
Auroral emissions are a reflection of magnetospheric processes, and, at Jupiter, it is not entirely certain how the morphology of the UV main emission (ME) varies with magnetospher…
Study of Io's sodium jets with the TRAPPIST telescopes
Alexander de Becker, Linus Head, Bertrand Bonfond +7
Io is the most volcanically active body in the Solar System. This volcanic activity results in the ejection of material into Io's atmosphere, which may then escape from the atmosph…
A high spatial and spectral resolution study of Jupiter's mid-infrared auroral emissions and their response to a solar wind compression
James A Sinclair, Thomas K Greathouse, Rohini S Giles +11
We present mid-infrared spectroscopy of Jupiter's mid-to-high latitudes using Gemini-North/TEXES (Texas Echelon Cross Echelle Spectrograph) on March 17-19, 2017. These observations…
Enhanced CH absorption within Jupiter's southern auroral oval from Juno UVS observations
Rohini S. Giles, Vincent Hue, Thomas K. Greathouse +9
Reflected sunlight observations from the Ultraviolet Spectrograph (UVS) on the Juno spacecraft were used to study the distribution of acetylene (CH) at Jupiter's south pole…
Alternating north-south brightness ratio of Ganymede's auroral ovals: Hubble Space Telescope observations around the Juno PJ34 flyby
Joachim Saur, Stefan Duling, Alexandre Wennmacher +17
We report results of Hubble Space Telescope observations from Ganymede's orbitally trailing side which were taken around the flyby of the Juno spacecraft on June 7, 2021. We find t…
Jupiter's X-ray aurora during UV dawn storms and injections as observed by XMM-Newton, Hubble, and Hisaki
A. D. Wibisono, G. Branduardi-Raymont, W. R. Dunn +9
We present results from a multiwavelength observation of Jupiter's northern aurorae, carried out simultaneously by XMM-Newton, the Hubble Space Telescope (HST), and the Hisaki sate…
Meridional variations of CH in Jupiter's stratosphere from Juno UVS observations
Rohini S. Giles, Thomas K. Greathouse, Vincent Hue +10
The UVS instrument on the Juno mission records far-ultraviolet reflected sunlight from Jupiter. These spectra are sensitive to the abundances of chemical species in the upper atmos…
A sublimated water atmosphere on Ganymede detected from Hubble Space Telescope observations
Lorenz Roth, Nickolay Ivchenko, G. Randall Gladstone +5
Ganymede's atmosphere is produced by charged particle sputtering and sublimation of its icy surface. Previous far-ultraviolet observations of the O{\small I\,}1356-Å and O{\small I…
Detection of a bolide in Jupiter's atmosphere with Juno UVS
Rohini S. Giles, Thomas K. Greathouse, Joshua A. Kammer +9
The UVS instrument on the Juno mission recorded transient bright emission from a point source in Jupiter's atmosphere. The spectrum shows that the emission is consistent with a 960…
Possible Transient Luminous Events observed in Jupiter's upper atmosphere
Rohini S. Giles, Thomas K. Greathouse, Bertrand Bonfond +10
11 transient bright flashes were detected in Jupiter's atmosphere using the UVS instrument on the Juno spacecraft. These bright flashes are only observed in a single spin of the sp…
How Jupiter's Unusual Magnetospheric Topology Structures Its Aurora
Binzheng Zhang, Peter A. Delamere, Zhonghua Yao +10
Jupiter's bright persistent polar aurora and Earth's dark polar region indicate that the planets' magnetospheric topologies are very different. High-resolution global simulations s…
Six pieces of evidence against the corotation enforcement theory to explain the main aurora at Jupiter
Bertrand Bonfond, Zhonghua Yao, Denis Grodent
The most remarkable feature of the ultraviolet auroras at Jupiter is the ever present and almost continuous curtain of bright emissions centered on each magnetic pole and called th…
Auroral diagnosis of solar wind interaction with Jupiter's magnetosphere
Z. H. Yao, B. Bonfond, D. Grodent +11
Although mass and energy in Jupiter's magnetosphere mostly come from the innermost Galilean moon Io's volcanic activities, solar wind perturbations can play crucial roles in releas…
Observing Jupiter's polar stratospheric haze with HST/STIS. An HST White Paper
Denis Grodent, Bertrand Bonfond, Jonathan Nichols
The purpose of this HST white paper is to demonstrate that it is possible to monitor Jupiter's polar haze with HST/STIS without breaking the ground screening limit for bright objec…
