Studying tidal effects in planetary systems with Posidonius. A N-body simulator written in Rust
Sergi Blanco-Cuaresma, Emeline Bolmont
Planetary systems with several planets in compact orbital configurations such as TRAPPIST-1 are surely affected by tidal effects. Its study provides us with important insight about…
Habitability in Brown Dwarf Systems
Emeline Bolmont
The very recent discovery of planets orbiting very low mass stars sheds light on these exotic objects. Planetary systems around low-mass stars and brown dwarfs are very different f…
The fate of close-in planets: tidal or magnetic migration?
A. Strugarek, E. Bolmont, S. Mathis +4
Planets in close-in orbits interact magnetically and tidally with their host stars. These interactions lead to a net torque that makes close-in planets migrate inward or outward de…
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…
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…
Tidal dissipation in rotating low-mass stars and implications for the orbital evolution of close-in massive planets. II. Effect of stellar metallicity
Emeline Bolmont, Florian Gallet, Stéphane Mathis +3
Observations of hot Jupiter type exoplanets suggest that their orbital period distribution depends on the metallicity of their host star. We investigate here whether the impact of…
