Colour and Tropospheric Cloud Structure of Jupiter from MUSE/VLT: Retrieving a Universal Chromophore
Ashwin S. Braude, Patrick G. J. Irwin, Glenn S. Orton +1
Recent work by Sromovsky et al. (2017, Icarus 291, 232-244) suggested that all red colour in Jupiter's atmosphere could be explained by a single colour-carrying compound, a so-call…
Uranus in Northern Mid-Spring: Persistent Atmospheric Temperatures and Circulations Inferred from Thermal Imaging
Michael T. Roman, Leigh N. Fletcher, Glenn S. Orton +2
We present results from mid-infrared imaging of Uranus at wavelengths of 13.0 micron and 18.7 micron, sensing emission from the stratosphere and upper troposphere, acquired using t…
Toward the Analysis of JWST Exoplanet Spectra: the effective temperature in the context of direct imaging
Jean-Loup Baudino, J. Taylor, P. G. J. Irwin +1
The current sparse wavelength range coverage of exoplanet direct imaging observations, and the fact that models are defined using a finite wavelength range, lead both to uncertaint…
Ethane in Titan's Stratosphere from Cassini CIRS Far- and Mid-Infrared Spectra
Nicholas A Lombardo, Conor A Nixon, Melody Sylvestre +4
The Cassini Composite Infrared Spectrometer (CIRS) observed thermal emission in the far- and mid-infrared (from 10 cm to 1500 cm), enabling spatiotemporal studies of…
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…
