Spin evolution of Venus-like planets subjected to gravitational and thermal tides
Alexandre Revol, Émeline Bolmont, Gabriel Tobie +5
The arrival of powerful instruments will provide valuable data for the characterization of rocky exoplanets. It is then crucial to accurately model the dynamical state of exoplanet…
Gravitational atmospheric tides as a probe of Titan's interior: Application to Dragonfly
Benjamin Charnay, Gabriel Tobie, Sébastien Lebonnois +1
Context: Saturn's massive gravity is expected to causes a tide in Titan's atmosphere, producing a surface pressure variation through the orbit of Titan and tidal winds in the tropo…
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…
Solid tidal friction in multi-layer planets: Application to Earth, Venus, a Super Earth and the TRAPPIST-1 planets. Can a multi-layer planet be approximated as a homogeneous planet?
Emeline Bolmont, Sylvain N. Breton, Gabriel Tobie +3
With the discovery of TRAPPIST-1 and its seven planets within 0.06 au, the correct treatment of tidal interactions is becoming necessary. The eccentricity, rotation, and obliquity…
The Science Case for a Titan Flagship-class Orbiter with Probes
Conor A. Nixon, James Abshire, Andrew Ashton +36
We outline a flagship-class mission concept focused on studying Titan as a global system, with particular emphasis on the polar regions. Investigating Titan from the unique standpo…
A Recipe for Geophysical Exploration of Enceladus
Anton I. Ermakov, Ryan S. Park, Javier Roa +13
Orbital geophysical investigations of Enceladus are critical to understanding its energy balance. We identified key science questions for the geophysical exploration of Enceladus,…
Photometrically-corrected global infrared mosaics of Enceladus: New implications for its spectral diversity and geological activity
Rozenn Robinel, Stéphane Le Mouélic, Gabriel Tobie +4
Between 2004 and 2017, spectral observations have been gathered by the Visual and Infrared Mapping Spectrometer (VIMS) on-board Cassini (Brown et al., 2004) during 23 Enceladus clo…
Science goals and mission concepts for a future orbital and in situ exploration of Titan
Sébastien Rodriguez, Sandrine Vinatier, Daniel Cordier +27
In this white paper, we present a cross-section of important scientific questions that remain partially or completely unanswered, ranging from Titan exosphere to the deep interior,…
Ice Giant Systems: The Scientific Potential of Orbital Missions to Uranus and Neptune
Leigh N. Fletcher, Ravit Helled, Elias Roussos +27
Uranus and Neptune, and their diverse satellite and ring systems, represent the least explored environments of our Solar System, and yet may provide the archetype for the most comm…
Tidal heating in multilayer planets: Application to the TRAPPIST-1 system
Sylvain Breton, Emeline Bolmont, Gabriel Tobie +1
TRAPPIST-1 (Gillon et al. 2017) is an extremely compact planetary system: seven earth-sized planets orbit at distances lower than 0.07 AU around one of the smallest M-dwarf known i…
Water and the interior structure of terrestrial planets and icy bodies
Julien Monteux, Gregor J. Golabek, David C. Rubie +2
Water content and the internal evolution of terrestrial planets and icy bodies are closely linked. The distribution of water in planetary systems is controlled by the temperature s…
Role of the global water ocean on the evolution of Titan's primitive atmosphere
Nadejda Marounina, Olivier Grasset, Gabriel Tobie +1
During the accretion of Titan, impact heating may have been sufficient to allow the global melting of water ice and the release of volatile compounds, mainly constituted of CO2, CH…
Modelling climate diversity, tidal dynamics and the fate of volatiles on TRAPPIST-1 planets
Martin Turbet, Emeline Bolmont, Jeremy Leconte +6
TRAPPIST-1 planets are invaluable for the study of comparative planetary science outside our Solar System and possibly habitability. First, we derive from N-body simulations possib…
CO2 condensation is a serious limit to the deglaciation of Earth-like planets
Martin Turbet, Francois Forget, Jeremy Leconte +2
It is widely believed that the carbonate-silicate cycle is the main agent to trigger deglaciations by CO greenhouse warming on Earth and on Earth-like planets when they get in…
New constraints on Saturn's interior from Cassini astrometric data
Valéry Lainey, Robert A. Jacobson, Radwan Tajeddine +15
Using astrometric observations spanning more than a century and including a large set of Cassini data, we determine Saturn's tidal parameters through their current effects on the o…
Titan's past and future: 3D modeling of a pure nitrogen atmosphere and geological implications
Benjamin Charnay, François Forget, Gabriel Tobie +2
Several clues indicate that Titan's atmosphere has been depleted in methane during some period of its history, possibly as recently as 0.5-1 billion years ago. It could also happen…
Strong tidal dissipation in Saturn and constraints on Enceladus' thermal state from astrometry
V. Lainey, Ö. Karatekin, J. Desmars +8
Tidal interactions between Saturn and its satellites play a crucial role in both the orbital migration of the satellites and the heating of their interiors. Therefore constraining…
Accretion of Saturn's mid-sized moons during the viscous spreading of young massive rings: solving the paradox of silicate-poor rings versus silicate-rich moons
Sébastien Charnoz, Aurélien Crida, Julie C. Castillo-Rogez +7
The origin of Saturn's inner mid-sized moons (Mimas, Enceladus, Tethys, Dione and Rhea) and Saturn's rings is debated. Charnoz et al. (2010) introduced the idea that the smallest i…
Global circulation as the main source of cloud activity on Titan
Sébastien Rodriguez, Stéphane Le Mouélic, Pascal Rannou +11
Clouds on Titan result from the condensation of methane and ethane and, as on other planets, are primarily structured by circulation of the atmosphere. At present, cloud activity m…
