Cloud and ammonia vertical profiles in the equatorial atmosphere of Jupiter determined from visible to near-IR observations made by VLT/MUSE, Cassini/VIMS, IRTF/SpeX and Juno/JIRAM
Patrick G. J. Irwin, Asier Anguiano-Arteaga, Michelle Colantoni +8
We present a combined cloud/ammonia model for Jupiter's equatorial atmosphere from 0.1 to 10 bar, consistent with observations made at a range of observation geometries from 0.35 t…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Key Targets of Opportunity on Gas and Ice Giants and their satellites
Ricardo Hueso, Leigh N. Fletcher, Damya Souami +15
The Extremely Large Telescope (ELT) will transform our knowledge of the outer planets and their satellite systems; however the visibility of unique targets of opportunity with high…
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…
Observations of the temporal evolution of Saturn's stratosphere following the Great Storm of 2010-2011 I. Temporal evolution of the water abundance in Saturn's hot vortex of 2011-2013
Camille Lefour, Thibault Cavalié, Helmut Feuchtgruber +6
Water vapour is delivered to Saturn's stratosphere by Enceladus' plumes and subsequent diffusion in the planet system. It is expected to condense into a haze in the middle stratosp…
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…
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…
A retrospective analysis of mid-infrared observations of the Comet D/Shoemaker-Levy 9 and Wesley impacts on Jupiter
James A. Sinclair, Carey M. Lisse, Glenn S. Orton +5
We present a retrospective analysis of Earth-based mid-infrared observations of Jupiter capturing the aftermath of the impacts by Comet D/Shoemaker-Levy 9 (henceforth SL9) in July…
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…
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…
Saturn's Seasonal Atmosphere at Northern Summer Solstice
L. N. Fletcher, L. Sromovsky, V. Hue +4
The incredible longevity of Cassini's orbital mission at Saturn has provided the most comprehensive exploration of a seasonal giant planet to date. This review explores Saturn's ch…
Mapping of Jupiter's tropospheric NH abundance using ground-based IRTF/TEXES observations at 5 m
Doriann Blain, Thierry Fouchet, Thomas Greathouse +8
We report on results of an observing campaign to support the Juno mission. At the beginning of 2016, using TEXES (Texas Echelon cross-dispersed Echelle Spectrograph), mounted on th…
The quest for H at Neptune: deep burn observations with NASA IRTF iSHELL
H. Melin, L. N. Fletcher, T. S. Stallard +4
Emission from the molecular ion H is a powerful diagnostic of the upper atmosphere of Jupiter, Saturn, and Uranus, but it remains undetected at Neptune. In search of this emi…
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…
EChO - Exoplanet Characterisation Observatory
G. Tinetti, J. P. Beaulieu, T. Henning +131
A dedicated mission to investigate exoplanetary atmospheres represents a major milestone in our quest to understand our place in the universe by placing our Solar System in context…
The impact of a large object with Jupiter in July 2009
A. Sánchez-Lavega, A. Wesley, G. Orton +13
On 2009 July 19, we observed a single, large impact on Jupiter at a planetocentric latitude of 55^{\circ}S. This and the Shoemaker-Levy 9 (SL9) impacts on Jupiter in 1994 are the o…
