A cool runaway greenhouse without surface magma ocean
Franck Selsis, Jérémy Leconte, Martin Turbet +2
Water vapour atmospheres with content equivalent to the Earth's oceans, resulting from impacts or a high insolation, were found to yield a surface magma ocean. This was, however, a…
3D Global climate model of an exo-Venus: a modern Venus-like atmosphere for the nearby super-Earth LP 890-9 c
Diogo Quirino, Gabriella Gilli, Lisa Kaltenegger +6
The recently discovered super-Earth LP 890-9 c is an intriguing target for atmospheric studies as it transits a nearby, low-activity late-type M-dwarf star at the inner edge of the…
Water Condensation Zones around Main Sequence Stars
Martin Turbet, Thomas J. Fauchez, Jeremy Leconte +10
Understanding the set of conditions that allow rocky planets to have liquid water on their surface -- in the form of lakes, seas or oceans -- is a major scientific step to determin…
ATMOSPHERIX: II- Characterising exoplanet atmospheres through transmission spectroscopy with SPIRou
F. Debras, B. Klein, J. -F. Donati +26
In a companion paper, we introduced a publicly-available pipeline to characterise exoplanet atmospheres through high-resolution spectroscopy. In this paper, we use this pipeline to…
ATMOSPHERIX: I- An open source high resolution transmission spectroscopy pipeline for exoplanets atmospheres with SPIRou
B. Klein, F. Debras, J. -F. Donati +28
Atmospheric characterisation of exoplanets from the ground is an actively growing field of research. In this context we have created the ATMOSPHERIX consortium: a research project…
A broadband thermal emission spectrum of the ultra-hot Jupiter WASP-18b
Louis-Philippe Coulombe, Björn Benneke, Ryan Challener +73
Close-in giant exoplanets with temperatures greater than 2,000 K (''ultra-hot Jupiters'') have been the subject of extensive efforts to determine their atmospheric properties using…
