Evidence for auroral influence on Jupiter's nitrogen and oxygen chemistry revealed by ALMA
Thibault Cavalié, Ladislav Rezac, Raphael Moreno +10
The localized delivery of new long-lived species to Jupiter's stratosphere by comet Shoemaker-Levy 9 in 1994 opened a window to constrain Jovian chemistry and dynamics by monitorin…
Science goals and new mission concepts for future exploration of Titan's atmosphere geology and habitability: Titan POlar Scout/orbitEr and In situ lake lander and DrONe explorer (POSEIDON)
Sébastien Rodriguez, Sandrine Vinatier, Daniel Cordier +61
In response to ESA Voyage 2050 announcement of opportunity, we propose an ambitious L-class mission to explore one of the most exciting bodies in the Solar System, Saturn largest m…
First direct measurement of auroral and equatorial jets in the stratosphere of Jupiter
T. Cavalié, B. Benmahi, V. Hue +11
Context. The tropospheric wind pattern in Jupiter consists of alternating prograde and retrograde zonal jets with typical velocities of up to 100 m/s around the equator. At much hi…
1D photochemical model of the ionosphere and the stratosphere of Neptune
M. Dobrijevic, J. C. Loison, V. Hue +2
Neptune remains a mysterious world that deserves further exploration and is a high-priority objective for a future planetary mission in order to better understand the formation and…
A Kinetic Study of the N(2D) + C2H4 Reaction at Low Temperature
Kevin M. Hickson, Cédric Bray, Jean-Christophe Loison +1
Electronically excited nitrogen atoms N(2D) are important species in the photochemistry of N2 based planetary atmospheres such as Titan. Despite this, few N(2D) reactions have been…
18-year long monitoring of the evolution of H2O vapor in the stratosphere of Jupiter with the Odin space telescope
B. Benmahi, T. Cavalié, M. Dobrijevic +14
Comet Shoemaker-Levy 9 impacted Jupiter in July 1994, leaving its stratosphere with several new species, among them water vapor (H2O). With the aid of a photochemical model H2O can…
The deep composition of Uranus and Neptune from in situ exploration and thermochemical modeling
Thibault Cavalié, Olivia Venot, Yamila Miguel +7
The distant ice giants of the Solar System, Uranus and Neptune, have only been visited by one space mission, Voyager 2. The current knowledge on their composition remains very limi…
Herschel map of Saturn's stratospheric water, delivered by the plumes of Enceladus
T. Cavalié, V. Hue, P. Hartogh +13
Context. The origin of water in the stratospheres of Giant Planets has been an outstanding question ever since its first detection by ISO some 20 years ago. Water can originate fro…
A reduced chemical scheme for modelling warm to hot hydrogen-dominated atmospheres
Olivia Venot, Roda Bounaceur, Michel Dobrijevic +5
Three dimensional models that account for chemistry are useful tools to predict the chemical composition of (exo)planet and brown dwarf atmospheres and interpret observations of fu…
Photochemistry, mixing and transport in Jupiter's stratosphere constrained by Cassini
Vincent Hue, Franck Hersant, Thibault Cavalié +2
We aim at constraining the diffusive and advective transport processes in Jupiter's stratosphere. The IR spectrum recorded by Cassini/CIRS during the Jupiter flyby contains the fin…
Scientific rationale for Uranus and Neptune in situ explorations
O. Mousis, D. H. Atkinson, T. Cavalié +53
The ice giants Uranus and Neptune are the least understood class of planets in our solar system but the most frequently observed type of exoplanets. Presumed to have a small rocky…
2D photochemical modeling of Saturn's stratosphere. Part I: Seasonal variation of atmospheric composition without meridional transport
Vincent Hue, Thibault Cavalié, Michel Dobrijevic +2
Saturn's axial tilt of 26.7° produces seasons in a similar way as on Earth. Both the stratospheric temperature and composition are affected by this latitudinally varying insolation…
VUV-absorption cross section of CO2 at high temperatures and impact on exoplanet atmospheres
Olivia Venot, Nicolas Fray, Yves Bénilan +6
Ultraviolet (UV) absorption cross sections are an essential ingredient of photochemical atmosphere models. Exoplanet searches have unveiled a large population of short-period objec…
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…
High-temperature measurements of VUV-absorption cross sections of CO2 and their application to exoplanets
Olivia Venot, Nicolas Fray, Yves Bénilan +6
UV absorption cross sections are an essential ingredient of photochemical atmosphere models. Exoplanet searches have unveiled a large population of short-period objects with hot at…
The impact of atmospheric circulation on the chemistry of the hot Jupiter HD 209458b
M. Agundez, O. Venot, N. Iro +4
We investigate the effects of atmospheric circulation on the chemistry of the hot Jupiter HD 209458b. We use a simplified dynamical model and a robust chemical network, as opposed…
A chemical model for the atmosphere of hot Jupiters
Olivia Venot, Eric Hébrard, Marcelino Agùndez +5
Our purpose is to release a chemical network, and the associated rate coefficients, developed for the temperature and pressure range relevant to hot Jupiters atmospheres. Using thi…
