Innocent Bystanders: Orbital Dynamics of Exomoons during Planet-Planet Scattering
Yu-Cian Hong, Sean N. Raymond, Philip D. Nicholson +1
Planet-planet scattering is the leading mechanism to explain the broad eccentricity distribution of observed giant exoplanets. Here we study the orbital stability of primordial gia…
280 one-opposition near-Earth asteroids recovered by the EURONEAR with the Isaac Newton Telescope
O. Vaduvescu, L. Hudin, T. Mocnik +80
One-opposition near-Earth asteroids (NEAs) are growing in number, and they must be recovered to prevent loss and mismatch risk, and to improve their orbits, as they are likely to b…
Implications of the interstellar object 1I/'Oumuamua for planetary dynamics and planetesimal formation
Sean N. Raymond, Philip J. Armitage, Dimitri Veras +2
'Oumuamua, the first bona-fide interstellar planetesimal, was discovered passing through our Solar System on a hyperbolic orbit. This object was likely dynamically ejected from an…
Atmospheric thermal tides and planetary spin I. The complex interplay between stratification and rotation
Pierre Auclair-Desrotour, Stéphane Mathis, Jacques Laskar
Thermal atmospheric tides can torque telluric planets away from spin-orbit synchronous rotation, as observed in the case of Venus. They thus participate to determine the possible c…
Atmospheric tides and their consequences on the rotational dynamics of terrestrial planets
Pierre Auclair-Desrotour, Jacques Laskar, Stéphane Mathis
Atmospheric tides can have a strong impact on the rotational dynamics of planets. They are of most importance for terrestrial planets located in the habitable zone of their host st…
The Empty Primordial Asteroid Belt
Sean N. Raymond, Andre Izidoro
The asteroid belt contains less than a thousandth of Earth's mass and is radially segregated, with S-types dominating the inner belt and C-types the outer belt. It is generally ass…
Temporal evolution of the high-energy irradiation and water content of TRAPPIST-1 exoplanets
V. Bourrier, J. de Wit, E. Bolmont +13
The ultracool dwarf star TRAPPIST-1 hosts seven Earth-size transiting planets, some of which could harbour liquid water on their surfaces. UV observations are essential to measure…
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…
Origin of water in the inner Solar System: Planetesimals scattered inward during Jupiter and Saturn's rapid gas accretion
Sean N. Raymond, Andre Izidoro
There is a long-standing debate regarding the origin of the terrestrial planets' water as well as the hydrated C-type asteroids. Here we show that the inner Solar System's water is…
The ARIEL Mission Reference Sample
Tiziano Zingales, Giovanna Tinetti, Ignazio Pillitteri +3
The ARIEL (Atmospheric Remote-sensing Exoplanet Large-survey) mission concept is one of the three M4 mission candidates selected by the European Space Agency (ESA) for a Phase A st…
The Role of Disc Self-Gravity in Circumbinary Planet Systems: II. Planet Evolution
Matthew M. Mutter, Arnaud Pierens, Richard P. Nelson
We present the results of hydrodynamic simulations examining migration and growth of planets embedded in self-gravitating circumbinary discs. The binary star parameters are chosen…
A deeper view of the CoRoT-9 planetary system. A small non-zero eccentricity for CoRoT-9b likely generated by planet-planet scattering
A. S. Bonomo, G. Hébrard, S. N. Raymond +27
CoRoT-9b is one of the rare long-period (P=95.3 days) transiting giant planets with a measured mass known to date. We present a new analysis of the CoRoT-9 system based on five yea…
Thermochemistry and vertical mixing in the tropospheres of Uranus and Neptune: How convection inhibition can affect the derivation of deep oxygen abundances
Thibault Cavalié, Olivia Venot, Franck Selsis +3
Thermochemical models have been used in the past to constrain the deep oxygen abundance in the gas and ice giant planets from tropospheric CO spectroscopic measurements. Knowing th…
A seven-planet resonant chain in TRAPPIST-1
Rodrigo Luger, Marko Sestovic, Ethan Kruse +30
The TRAPPIST-1 system is the first transiting planet system found orbiting an ultra-cool dwarf star. At least seven planets similar to Earth in radius and in mass were previously f…
A Surface Density Perturbation in the TW Hydrae Disk at 95 au Traced by Molecular Emission
R Teague, D Semenov, U Gorti +6
We present ALMA Cycle~2 observations at resolution of TW Hya of CS emission. The radial profile of the integrated line emission displays oscillatory fe…
