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…
Improved H2-He and H2-H2 Collision-Induced Absorption Models and Application to Outer-Planet Atmospheres
Glenn S. Orton, Magnus Gustafsson, Leigh N. Fletcher +2
Using state-of-the-art ab initio interaction-induced dipole and potential-energy surfaces for hydrogen-helium (H2-He) pairs, we compute the rototranslational collision-induced abso…
The Thermal Structure and Composition of Jupiter's Great Red Spot From JWST/MIRI
Jake Harkett, Leigh N. Fletcher, Oliver R. T. King +15
Jupiter's Great Red Spot (GRS) was mapped by the James Webb Space Telescope (JWST)/Mid-Infrared Instrument (4.9-27.9 micron) in July and August 2022. These observations took place…
Jovian Vortex Hunter: a citizen science project to study Jupiter's vortices
Ramanakumar Sankar, Shawn Brueshaber, Lucy Fortson +4
The Jovian atmosphere contains a wide diversity of vortices, which have a large range of sizes, colors and forms in different dynamical regimes. The formation processes for these v…
Temperature and composition disturbances in the southern auroral region of Jupiter revealed by JWST/MIRI
Pablo Rodríguez-Ovalle, Thierry Fouchet, Sandrine Guerlet +17
Jupiters south polar region was observed by JWST Mid Infrared Instrument in December 2022. We used the Medium Resolution Spectrometer mode to provide new information about Jupiters…
Super-adiabatic Temperature Gradient at Jupiter's Equatorial Zone and Implications for the Water Abundance
Cheng Li, Michael Allison, Sushil Atreya +12
The temperature structure of a giant planet was traditionally thought to be an adiabat assuming convective mixing homogenizes entropy. The only in-situ measurement made by the Gali…
Investigating Thermal Contrasts Between Jupiter's Belts, Zones, and Polar Vortices with VLT/VISIR
Deborah Bardet, Padraig T. Donnelly, Leigh N. Fletcher +8
Using images at multiple mid-infrared wavelengths, acquired in May 2018 using the VISIR instrument on ESO's Very Large Telescope (VLT), we study Jupiter's pole-to-pole thermal, che…
Latitudinal variations in methane abundance, aerosol opacity and aerosol scattering efficiency in Neptune's atmosphere determined from VLT/MUSE
Patrick G. J. Irwin, Jack Dobinson, Arjuna James +11
Spectral observations of Neptune made in 2019 with the MUSE instrument at the Very Large Telescope in Chile have been analysed to determine the spatial variation of aerosol scatter…
Hazy blue worlds: A holistic aerosol model for Uranus and Neptune, including Dark Spots
Patrick G. J. Irwin, Nicholas A. Teanby, Leigh N. Fletcher +7
We present a reanalysis (using the Minnaert limb-darkening approximation) of visible/near-infrared (0.3 - 2.5 micron) observations of Uranus and Neptune made by several instruments…
Evidence for multiple Ferrel-like cells on Jupiter
Keren Duer, Nimrod Gavriel, Eli Galanti +14
Jupiter's atmosphere is dominated by multiple jet streams which are strongly tied to its 3D atmospheric circulation. Lacking a rigid bottom boundary, several models exist for how t…
Refining Saturn's deuterium-hydrogen ratio via IRTF/TEXES spectroscopy
James S. D. Blake, Leigh N. Fletcher, Thomas K. Greathouse +7
The abundance of deuterium in giant planet atmospheres provides constraints on the reservoirs of ices incorporated into these worlds during their formation and evolution. Motivated…
HST/WFC3 Observations of Uranus' 2014 storm clouds and comparison with VLT/SINFONI and IRTF/SpeX observations
Patrick G. J. Irwin, Michael H. Wong, Amy A. Simon +2
Observations of Uranus were made on the 8/9th November with HST/WFC3 at a time when a huge cloud complex was present at 30 - 40N. We imaged Uranus in seven filters spanning 467 - 9…
Mid-Infrared Spectroscopy of Uranus from the Spitzer Infrared Spectrometer: 2. Determination of the Mean Composition of the Upper Troposphere and Stratosphere
Glenn S. Orton, J. I. Moses, Leigh N. Fletcher +7
Mid-infrared spectral observations Uranus acquired with the Infrared Spectrometer (IRS) on the Spitzer Space Telescope are used to determine the abundances of C2H2, C2H6, CH3C2H, C…
