Infrared Characterisation of Jupiter's Equatorial Disturbance Cycle
Arrate Antuñano, Leigh N. Fletcher, Glenn S. Orton +6
We use an infrared dataset captured between 1984 and 2017 using several instruments and observatories to report five rare equatorial disturbances that completely altered the appear…
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…
Unexpected Long-Term Variability in Jupiter's Tropospheric Temperatures
Glenn S. Orton, Arrate Antunano, Leigh N. Fletcher +9
An essential component of planetary climatology is knowledge of the tropospheric temperature field and its variability. Previous studies of Jupiter hinted at periodic behavior that…
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…
First ALMA Millimeter Wavelength Maps of Jupiter, with a Multi-Wavelength Study of Convection
Imke de Pater, R. J. Sault, Chris Moeckel +15
We obtained the first maps of Jupiter at 1-3 mm wavelength with the Atacama Large Millimeter/Submillimeter Array (ALMA) on 3-5 January 2017, just days after an energetic eruption a…
Jupiter's Atmospheric Variability from Long-Term Ground-based Observations at 5 microns
Arrate Antuñano, Leigh N. Fletcher, Glenn S. Orton +7
Jupiter's banded structure undergoes strong temporal variations, changing the visible and infrared appearance of the belts and zones in a complex and turbulent way due to physical…
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…
Assessing the long-term variability of acetylene and ethane in the stratosphere of Jupiter
Henrik Melin, L. N. Fletcher, P. T. Donnelly +6
Acetylene (CH) and ethane (CH) are both produced in the stratosphere of Jupiter via photolysis of methane (CH). Despite this common source, the latitudinal dist…
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…
Jupiter's North Equatorial Belt expansion and thermal wave activity ahead of Juno's arrival
L. N. Fletcher, G. S. Orton, J. A. Sinclair +13
The dark colors of Jupiter's North Equatorial Belt (NEB, N) appeared to expand northward into the neighboring zone in 2015, consistent with a 3-5 year cycle of activity…
