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…
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…
Latitudinal variation of methane mole fraction above clouds in Neptune's atmosphere from VLT/MUSE-NFM: Limb-darkening reanalysis
P. G. J. Irwin, J. Dobinson, A. James +5
We present a reanalysis of visible/near-infrared (480-930 nm) observations of Neptune, made in 2018 with the MUSE instrument at the Very Large Telescope (VLT) in Narrow Field Adapt…
Ice Giant Circulation Patterns: Implications for Atmospheric Probes
Leigh N. Fletcher, Imke de Pater, Glenn S. Orton +4
Atmospheric circulation patterns derived from multi-spectral remote sensing can serve as a guide for choosing a suitable entry site for a future in situ probe mission. Since the Vo…
Latitudinal variation in the abundance of methane (CH4) above the clouds in Neptune's atmosphere from VLT/MUSE Narrow Field Mode Observations
Patrick G. J. Irwin, Daniel Toledo, Ashwin S. Braude +5
Observations of Neptune, made in 2018 using the new Narrow Field Adaptive Optics mode of the Multi Unit Spectroscopic Explorer (MUSE) instrument at the Very Large Telescope (VLT) f…
Probable detection of hydrogen sulphide (HS) in Neptune's atmosphere
Patrick G. J. Irwin, Daniel Toledo, Ryan Garland +4
Recent analysis of Gemini-North/NIFS H-band (1.45 - 1.8 m) observations of Uranus, recorded in 2010, with recently updated line data has revealed the spectral signature of hydro…
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…
