A seven-planet resonant chain in TRAPPIST-1
- R. Luger, M. Sestovic, +30 authors D. Queloz
- Physics
- 12 March 2017
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 found to transit… Expand
3D climate modeling of close-in land planets: Circulation patterns, climate moist bistability and habitability
- J. Leconte, F. Forget, B. Charnay, R. Wordsworth, F. Selsis, E. Millour
- Physics
- 28 March 2013
The inner edge of the classical habitable zone is often defined by the critical flux needed to trigger the runaway greenhouse instability. This 1D notion of a critical flux, however, may not be so… Expand
Is tidal heating sufficient to explain bloated exoplanets? Consistent calculations accounting for finite initial eccentricity
- J. Leconte, G. Chabrier, I. Baraffe, B. Levrard
- Physics
- 3 April 2010
We present the consistent evolution of short-period exoplanets coupling the tidal and gravothermal evolution of the planet. Contrarily to previous similar studies, our calculations are based on the… Expand
The nature of the TRAPPIST-1 exoplanets.
Context. The TRAPPIST-1 system hosts seven Earth-sized, temperate exoplanets orbiting an ultra-cool dwarf star. As such, it represents a remarkable setting to study the formation and evolution of… Expand
The habitability of Proxima Centauri b. I. Irradiation, rotation and volatile inventory from formation to the present
- I. Ribas, É. Bolmont, +9 authors G. Anglada-Escudé
- Physics
- 24 August 2016
Proxima b is a planet with a minimum mass of 1.3 MEarth orbiting within the habitable zone (HZ) of Proxima Centauri, a very low-mass, active star and the Sun's closest neighbor. Here we investigate a… Expand
Exploring the faint young Sun problem and the possible climates of the Archean Earth with a 3-D GCM
- B. Charnay, F. Forget, +4 authors A. Spiga
- Environmental Science, Physics
- 27 September 2013
[1] Different solutions have been proposed to solve the “faint young Sun problem,” defined by the fact that the Earth was not fully frozen during the Archean despite the fainter Sun. Most previous… Expand
A new vision of giant planet interiors: Impact of double diffusive convection
- J. Leconte, G. Chabrier
- Physics
- 21 January 2012
While conventional interior models for Jupiter and Saturn are based on the simplistic assumption of a solid core surrounded by a homogeneous gaseous envelope, we have derived new models with an… Expand
Water loss from terrestrial planets orbiting ultracool dwarfs: implications for the planets of TRAPPIST-1
- É. Bolmont, F. Selsis, +4 authors M. Gillon
- Physics
- 2 May 2016
Ultracool dwarfs (UCD) encompass the population of extremely low mass stars (later than M6-type) and brown dwarfs. Because UCDs cool monotonically, their habitable zone (HZ) sweeps inward in time.… Expand
The habitability of Proxima Centauri b II. Possible climates and Observability
- M. Turbet, J. Leconte, +5 authors G. Anglada-Escudé
- Physics
- 24 August 2016
Radial velocity monitoring has found the signature of a $M \sin i = 1.3$~M$_\oplus$ planet located within the Habitable Zone (HZ) of Proxima Centauri \citep{Anglada16}. Despite a hotter past and an… Expand
Layered convection as the origin of Saturn/'s luminosity anomaly
- J. Leconte, G. Chabrier
- Physics
- 23 April 2013
Saturn is brighter than expected for a gas giant of its age. Calculations of Saturn’s thermal evolution show that the presence of layered convection in Saturn’s interior—much like that observed in… Expand
