We present a study of the long term variability of Jupiter's mid-infrared auroral CH4 emissions. 7.7 - 7.9 micron images of Jupiter recorded by Earth-based telescopes over the last…
The Io, Europa and Ganymede auroral footprints at Jupiter in the ultraviolet: positions and equatorial lead angles
Vincent Hue, Randy Gladstone, Corentin K. Louis +16
Jupiter's satellite auroral footprints are a consequence of the interaction between the Jovian magnetic field with co-rotating iogenic plasma and the Galilean moons. The disturbanc…
A high spatial and spectral resolution study of Jupiter's mid-infrared auroral emissions and their response to a solar wind compression

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…
Jupiter Science Enabled by ESA's Jupiter Icy Moons Explorer
Leigh N. Fletcher, Thibault Cavalié, Davide Grassi +47
ESA's Jupiter Icy Moons Explorer (JUICE) will provide a detailed investigation of the Jovian system in the 2030s, combining a suite of state-of-the-art instruments with an orbital…
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…
Three-dimensional structure of thermal waves in Venus' mesosphere from ground-based observations
Rohini S Giles, Thomas K Greathouse, Patrick G J Irwin +2
High spectral resolution observations of Venus were obtained with the TEXES instrument at NASA's Infrared Telescope Facility. These observations focus on a CO absorption featur…
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…
Mapping the zonal winds of Jupiter's stratospheric equatorial oscillation
B. Benmahi, T. Cavalié, T. K. Greathouse +5
Since the 1950s, quasi-periodic oscillations have been studied in the terrestrial equatorial stratosphere. Other planets of the solar system present (or are expected to present) su…
Detection of a bolide in Jupiter's atmosphere with Juno UVS
