A seven-planet resonant chain in TRAPPIST-1
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 transitExpand

3D climate modeling of close-in land planets: Circulation patterns, climate moist bistability and habitability
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 soExpand

Is tidal heating sufficient to explain bloated exoplanets? Consistent calculations accounting for finite initial eccentricity
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 theExpand

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 ofExpand

The habitability of Proxima Centauri b. I. Irradiation, rotation and volatile inventory from formation to the present
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 aExpand

Exploring the faint young Sun problem and the possible climates of the Archean Earth with a 3-D GCM
[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 previousExpand

A new vision of giant planet interiors: Impact of double diffusive convection
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 anExpand

Water loss from terrestrial planets orbiting ultracool dwarfs: implications for the planets of TRAPPIST-1
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
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 anExpand

Layered convection as the origin of Saturn/'s luminosity anomaly
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 inExpand
