Colour changes of Jupiter's Oval BA through microphysical modelling
Asier Anguiano-Arteaga, Santiago Pérez-Hoyos, Agustín Sánchez-Lavega +1
Jupiter's Oval BA undergoes recurrent colour changes whose physical origin remains uncertain. Radiative transfer retrievals indicate that these changes occur in the upper chromopho…
Microphysical Model of Jupiter's Great Red Spot Upper Chromophore Haze
Asier Anguiano-Arteaga, Santiago Perez-Hoyos, Agustin Sanchez-Lavega +1
The origin of the red colouration in Jupiter's Great Red Spot (GRS) is a long-standing question in planetary science. While several candidate chromophores have been proposed, no cl…
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…
The Origin of Jupiter's Great Red Spot
Agustín Sánchez-Lavega, Enrique García-Melendo, Jon Legarreta +3
Jupiter's Grat Red Spot (GRS) is the largest and longest-lived vortex of all solar system planets but its lifetime is debated and its formation mechanism remains hidden. G. D. Cass…
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…
Dynamics of Saturn's Polar Regions
A. Antuñano, T. del Río-Gaztelurrutia, A. Sánchez-Lavega +1
We analyze data retrieved by the Imaging Science System onboard the Cassini spacecraft to study the horizontal velocity and vorticity fields of Saturn's Polar Regions (latitudes 60…
A model of scattered thermal radiation for Venus from 3 to 5 m
A. García Muñoz, P. Wolkenberg, A. Sánchez-Lavega +2
Thermal radiation becomes a prominent feature in the continuum spectrum of Venus longwards of 3 m. The emission is traceable to the upper cloud and haze layers in the plan…
Instantaneous Three-dimensional Thermal Structure of the South Polar Vortex of Venus
I. Garate-Lopez, A. García Muñoz, R. Hueso +1
The Venus thermal radiation spectrum exhibits the signature of absorption bands. By means of inversion techniques, those bands enable the retrieval of atmospheric temperatur…
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…
Six years of Venus winds at the upper cloud level from UV, visible and near infrared observations from VIRTIS on Venus Express
Ricardo Hueso, Javier Peralta, Itziar Garate-Lopez +2
Venus Express provided a long-term monitoring of Venus atmosphere. Several works focused on the dynamics of the upper cloud visible on the day-side in ultraviolet images sensitive…
A chaotic long-lived vortex at Venus southern pole
I. Garate-Lopez, R. Hueso, A. Sánchez-Lavega +3
Polar vortices are common in the atmospheres of rapidly rotating planets [1-4]. On Earth and Mars they are tied to the surface and their existence follows the seasonal insolation c…
Multilayer hazes over Saturn's hexagon from Cassini ISS limb images
A. Sánchez-Lavega, A. García-Muñoz, T. del Río-Gaztelurrutia +5
In June 2015, Cassini high-resolution images of Saturn's limb southwards of the planet's hexagonal wave revealed a system of at least six stacked haze layers above the upper cloud…
Dynamics and Clouds in Planetary Atmospheres from Telescopic Observations
Agustín Sánchez-Lavega, Patrick Irwin, Antonio García Muñoz
This review presents an insight into our current knowledge of the atmospheres of the planets Venus, Mars, Jupiter, Saturn, Uranus and Neptune, the satellite Titan, and those of exo…
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…
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…
