Increased insolation threshold for runaway greenhouse processes on Earth-like planets
The increase in solar luminosity over geological timescales should warm the Earth’s climate, increasing water evaporation, which will in turn enhance the atmospheric greenhouse effect. Above aExpand
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
Global modelling of the early Martian climate under a denser CO2 atmosphere: Water cycle and ice evolution
Abstract We discuss 3D global simulations of the early martian climate that we have performed assuming a faint young Sun and denser CO 2 atmosphere. We include a self-consistent representation of theExpand
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
Gliese 581d is the First Discovered Terrestrial-mass Exoplanet in the Habitable Zone
It has been suggested that the recently discovered exoplanet GJ581d might be able to support liquid water due to its relatively low mass and orbital distance. However, GJ581d receives 35% lessExpand
Orbital and atmospheric characterization of the planet within the gap of the PDS 70 transition disk
Aims: We aim to characterize the orbital and atmospheric properties of PDS 70 b, which was first identified on May 2015 in the course of the SHINE survey with SPHERE, the extreme adaptive-opticsExpand
The Pale Orange Dot: The Spectrum and Habitability of Hazy Archean Earth
Abstract Recognizing whether a planet can support life is a primary goal of future exoplanet spectral characterization missions, but past research on habitability assessment has largely ignored theExpand
Titan global climate model: A new 3-dimensional version of the IPSL Titan GCM
Abstract We have developed a new 3-dimensional climate model for Titan’s atmosphere, using the physics of the IPSL Titan 2-dimensional climate model with the current version of the LMDZ GeneralExpand
3D modeling of GJ1214b's atmosphere: formation of inhomogeneous high clouds and observational implications
The warm sub-Neptune GJ1214b has a featureless transit spectrum which may be due to the presence of high and thick clouds or haze. Here, we simulate the atmosphere of GJ1214b with a 3D GeneralExpand
3D modeling of GJ1214b's atmosphere: vertical mixing driven by an anti-Hadley circulation
GJ1214b is a warm sub-Neptune transiting in front of a nearby M dwarf star. Recent observations indicate the presence of high and thick clouds or haze whose presence requires strong atmosphericExpand
