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…
A re-analysis of equilibrium chemistry in five hot Jupiters
Emilie Panek, Jean-Philippe Beaulieu, Pierre Drossart +4
Studying chemistry and chemical composition is fundamental to go back to formation history of planetary systems. We propose here to have another look at five targets to better dete…
Jupiter Science Enabled by ESA's Jupiter Icy Moons Explorer
Leigh N. Fletcher, Thibault Cavalié, Davide Grassi +47
ESA's Jupiter Icy Moons Explorer (JUICE) will provide a detailed investigation of the Jovian system in the 2030s, combining a suite of state-of-the-art instruments with an orbital…
Water Ortho-to-Para ratio in the coma of comet 67P/Churyumov-Gerasimenko
Y. -C. Cheng, D. Bockelée-Morvan, M. Roos-Serote +9
Abundance ratios of the nuclear-spin isomers of HO and NH have been measured in about two dozen comets, with a mean value corresponding to a nuclear-spin temperature of $\s…
ARES V: No Evidence For Molecular Absorption in the HST WFC3 Spectrum of GJ 1132 b
Lorenzo V. Mugnai, Darius Modirrousta-Galian, Billy Edwards +25
We present a study on the spatially scanned spectroscopic observations of the transit of GJ 1132 b, a warm (500 K) Super-Earth (1.13 R) that was obtained with the G1…
ARES IV: Probing the atmospheres of the two warm small planets HD 106315 c and HD 3167 c with the HST/WFC3 camera
Gloria Guilluy, Amélie Gressier, Sam Wright +27
We present an atmospheric characterization study of two medium sized planets bracketing the radius of Neptune: HD 106315 c (R=4.98 0.23 R) and HD 3167 c…
ARES III: Unveiling the Two Faces of KELT-7 b with HST WFC3
William Pluriel, Niall Whiteford, Billy Edwards +24
We present the analysis of the hot-Jupiter KELT-7b using transmission and emission spectroscopy from the Hubble Space Telescope (HST), both taken with the Wide Field Camera 3 (WFC3…
ARES II: Characterising the Hot Jupiters WASP-127 b, WASP-79 b and WASP-62 b with HST
Nour Skaf, Michelle Fabienne Bieger, Billy Edwards +24
This paper presents the atmospheric characterisation of three large, gaseous planets: WASP-127b, WASP-79b and WASP-62b. We analysed spectroscopic data obtained with the G141 grism…
ARES I: WASP-76 b, A Tale of Two HST Spectra
Billy Edwards, Quentin Changeat, Robin Baeyens +25
We analyse the transmission and emission spectra of the ultra-hot Jupiter WASP-76b, observed with the G141 grism of the Hubble Space Telescope's Wide Field Camera 3 (WFC3). We redu…
VIRTIS-H observations of comet 67P's dust coma: spectral properties and color temperature variability with phase and elevation
D. Bockelée-Morvan, C. Leyrat, S. Erard +14
We analyze 2-5 micrometre spectroscopic observations of the dust coma of comet 67P/Churyumov-Gerasimenko obtained with the VIRTIS-H instrument onboard Rosetta from 3 June to 29 Oct…
Mapping of Jupiter's tropospheric NH abundance using ground-based IRTF/TEXES observations at 5 m
Doriann Blain, Thierry Fouchet, Thomas Greathouse +8
We report on results of an observing campaign to support the Juno mission. At the beginning of 2016, using TEXES (Texas Echelon cross-dispersed Echelle Spectrograph), mounted on th…
Detection of exposed HO ice on the nucleus of comet 67P/Churyumov-Gerasimenko
M. A. Barucci, G. Filacchione, S. Fornasier +42
Since the orbital insertion of the Rosetta spacecraft, comet 67P/Churyumov-Gerasimenko (67P/C-G) has been mapped by OSIRIS camera and VIRTIS spectro-imager, producing a huge quanti…
The EChO science case
Giovanna Tinetti, Pierre Drossart, Paul Eccleston +347
The discovery of almost 2000 exoplanets has revealed an unexpectedly diverse planet population. Observations to date have shown that our Solar System is certainly not representativ…
EChO - Exoplanet Characterisation Observatory
G. Tinetti, J. P. Beaulieu, T. Henning +131
A dedicated mission to investigate exoplanetary atmospheres represents a major milestone in our quest to understand our place in the universe by placing our Solar System in context…
Neptune's Atmospheric Composition from AKARI Infrared Spectroscopy
Leigh N. Fletcher, Pierre Drossart, Martin Burgdorf +2
Aims: Disk-averaged infrared spectra of Neptune between 1.8 and 13 m, obtained by the AKARI Infrared Camera (IRC) in May 2007, have been analysed to (a) determine the globally-a…
