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…
A precise optical transmission spectrum of the inflated exoplanet WASP-52b
Tom Louden, Peter J. Wheatley, Patrick G. J. Irwin +2
We have measured a precise optical transmission spectrum for WASP-52b, a highly inflated hot Jupiter with an equilibrium temperature of 1300 K. Two transits of the planet were obse…
Rayleigh scattering in the transmission spectrum of HAT-P-18b
J. Kirk, P. J. Wheatley, T. Louden +5
We have performed ground-based transmission spectroscopy of the hot Jupiter HAT-P-18b using the ACAM instrument on the William Herschel Telescope (WHT). Differential spectroscopy o…
Cloud structure and composition of Jupiter's troposphere from 5-μm Cassini VIMS spectroscopy
Rohini S. Giles, Leigh N. Fletcher, Patrick G. J. Irwin
Jupiter's tropospheric composition and cloud structure are studied using Cassini VIMS 4.5-5.1 μm thermal emission spectra from the 2000-2001 flyby. We make use of both nadir and li…
Ethyl cyanide on Titan: Spectroscopic detection and mapping using ALMA
M. A. Cordiner, M. Y. Palmer, C. A. Nixon +9
We report the first spectroscopic detection of ethyl cyanide (CHCN) in Titan's atmosphere, obtained using spectrally and spatially resolved observations of multiple emissio…
The Origin of Nitrogen on Jupiter and Saturn from the N/N Ratio
Leigh N. Fletcher, Thomas K. Greathouse, Glenn S. Orton +4
The Texas Echelon cross Echelle Spectrograph (TEXES), mounted on NASA's Infrared Telescope Facility (IRTF), was used to map mid-infrared ammonia absorption features on both Jupiter…
Scientific rationale of Saturn's in situ exploration
O. Mousis, L. N. Fletcher, J. -P. Lebreton +47
Remote sensing observations meet some limitations when used to study the bulk atmospheric composition of the giant planets of our solar system. A remarkable example of the superior…
Abundances of Jupiter's Trace Hydrocarbons From Voyager and Cassini
Conor A. Nixon, Richard K. Achterberg, Paul N. Romani +5
The flybys of Jupiter by the Voyager spacecraft in 1979, and over two decades later by Cassini in 2000, have provided us with unique datasets from two different epochs, allowing th…
Titan's Prolific Propane: The Cassini CIRS Perspective
C. A. Nixon, D. E. Jennings, J. -M. Flaud +7
In this paper we select large spectral averages of data from the Cassini Composite Infrared Spectrometer (CIRS) obtained in limb-viewing mode at low latitudes (30S--30N), greatly i…
