Wind shear and the role of eddy vapor transport in driving water convection on Jupiter
Ramanakumar Sankar, Michael H Wong, Csaba Palotai +1
Recent observations of convection in the jovian atmosphere have demonstrated that convection is strongly concentrated at specific locations on planet. For instance, observations of…
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…
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…
An Enduring Rapidly Moving Storm as a Guide to Saturn's Equatorial Jet's Complex Structure
A. Sánchez-Lavega, E. García-Melendo, S. Perez-Hoyos +14
Saturn has an intense and broad eastward equatorial jet with a complex three-dimensional structure mixed with time variability. The equatorial region experiences strong seasonal in…
Three-dimensional atmospheric dynamics of Jupiter from ground-based Doppler imaging spectroscopy in the visible
François-Xavier Schmider, Patrick Gaulme, Raúl Morales-Juberías +25
We present three-dimensional (3D) maps of Jupiter's atmospheric circulation at cloud-top level from Doppler-imaging data obtained in the visible domain with JIVE, the second node o…
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…
Spectral determination of the colour and vertical structure of dark spots in Neptune's atmosphere
Patrick G. J. Irwin, Jack Dobinson, Arjuna James. Michael H. Wong +12
Previous observations of dark vortices in Neptune's atmosphere, such as Voyager-2's Great Dark Spot, have been made in only a few, broad-wavelength channels, which has hampered eff…
Evolution of Neptune at Near-Infrared Wavelengths from 1994 through 2022
Erandi Chavez, Imke de Pater, Erin Redwing +15
Using archival near-infrared observations from the Keck and Lick Observatories and the Hubble Space Telescope, we document the evolution of Neptune's cloud activity from 1994 to 20…
Drift Rates of Major Neptunian Features between 2018 and 2021
Erandi Chavez, Erin Redwing, Imke de Pater +13
Using near-infrared observations of Neptune from the Keck and Lick Observatories, and the Hubble Space Telescope in combination with amateur datasets, we calculated the drift rates…
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…
Jupiter's Mesoscale Waves Observed at 5 m by Ground-Based Observations and Juno JIRAM
L. N. Fletcher, H. Melin, A. Adriani +12
We characterise the origin and evolution of a mesoscale wave pattern in Jupiter's North Equatorial Belt (NEB), detected for the first time at 5 m using a 2016-17 campaign of `lu…
Jovian Temperature and Cloud Variability during the 2009-2010 Fade of the South Equatorial Belt
Leigh N. Fletcher, G. S. Orton, J. H. Rogers +7
Mid-infrared 7-20 m imaging of Jupiter demonstrates that the increased albedo of Jupiter's South Equatorial Belt (SEB) during the `fade' (whitening) event of 2009-2010 was corre…
Jupiter's Para-H Distribution from SOFIA/FORCAST and Voyager/IRIS 17-37 m Spectroscopy
Leigh N. Fletcher, I. de Pater, W. T. Reach +4
Spatially resolved maps of Jupiter's far-infrared 17-37 m hydrogen-helium collision-induced spectrum were acquired by the FORCAST instrument on the Stratospheric Observatory for…
Jupiter's Deep Cloud Structure Revealed Using Keck Observations of Spectrally Resolved Line Shapes
G. L. Bjoraker, M. H. Wong, I. de Pater +1
Technique: We present a method to determine the pressure at which significant cloud opacity is present between 2 and 6 bars on Jupiter. We use: a) the strength of a Fraunhofer abso…
The Puzzling Mutual Orbit of the Binary Trojan Asteroid (624) Hektor
F. Marchis, J. Durech, J. Castillo-Rogez +9
Asteroids with satellites are natural laboratories to constrain the formation and evolution of our solar system. The binary Trojan asteroid (624) Hektor is the only known Trojan as…
First Earth-based Detection of a Superbolide on Jupiter
R. Hueso, A. Wesley, C. Go +14
Cosmic collisions on planets cause detectable optical flashes that range from terrestrial shooting stars to bright fireballs. On June 3, 2010 a bolide in Jupiter's atmosphere was s…
