Comment on 'Radiative transfer in CO2-rich atmospheres: 1. Collisional line mixing implies a colder early Mars'
Martin Turbet, Ha Tran
Ozak et al. [2016] claimed that explicitly including the effect of CO collisional line mixing (LM) in their radiative transfer calculations yield CO atmospheres that are mo…
Methane release on Early Mars by atmospheric collapse and atmospheric reinflation
Edwin S. Kite, Michael A. Mischna, Peter Gao +2
A candidate explanation for Early Mars rivers is atmospheric warming due to surface release of H or CH gas. However, it remains unknown how much gas could be released in a…
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…
Seven temperate terrestrial planets around the nearby ultracool dwarf star TRAPPIST-1
Michael Gillon, Amaury H. M. J. Triaud, Brice-Olivier Demory +27
One focus of modern astronomy is to detect temperate terrestrial exoplanets well-suited for atmospheric characterisation. A milestone was recently achieved with the detection of th…
CO2 condensation is a serious limit to the deglaciation of Earth-like planets
Martin Turbet, Francois Forget, Jeremy Leconte +2
It is widely believed that the carbonate-silicate cycle is the main agent to trigger deglaciations by CO greenhouse warming on Earth and on Earth-like planets when they get in…
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…
3D Modelling of the climatic impact of outflow channel formation events on Early Mars
M. Turbet, F. Forget, J. W. Head +1
Mars was characterized by cataclysmic groundwater-sourced surface flooding that formed large outflow channels and that may have altered the climate for extensive periods during the…
