Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
A broad exploration of climate and observability of close-in rocky exoplanets: applications to Ross 128 b
Mathilde Houelle, Emeline Bolmont, Christophe Lovis +4
VLT/RISTRETTO, ELT/ANDES and ELT/PCS will soon enable atmospheric characterization of non-transiting, small rocky exoplanets orbiting closer than the inner edge of the Habitable Zo…
A Fast and Physically Grounded Ocean Model for GCMs: The Dynamical Slab Ocean Model of the Generic-PCM (rev. 3423)
Siddharth Bhatnagar, Francis Codron, Ehouarn Millour +5
Ocean dynamics are often sidelined in exoplanet climate studies due to the high computational cost of fully coupled atmosphere-ocean general circulation models (GCMs). However, oce…
Atmospheric Collapse and Habitability on Tidally-Locked Exoplanets
Keigo Taniguchi, Takanori Kodama, Martin Turbet +3
The habitability of terrestrial exoplanets orbiting M dwarfs is a key topic in the search for extraterrestrial life. The climates of these planets differ significantly from the Ear…
Climates of Terrestrial Exoplanets and Biosignatures
Siddharth Bhatnagar, Emeline Bolmont, Nikita J. Boeren +18
Understanding the climates of terrestrial exoplanets and the detectability of biosignatures is an inherently interdisciplinary challenge, requiring the integration of insights from…
Constraints on the possible atmospheres on TRAPPIST-1 b: insights from 3D climate modeling
Alice Maurel, Martin Turbet, Elsa Ducrot +13
JWST observations of the secondary eclipse of TRAPPIST-1 b at 12.8 and 15 microns revealed a very bright dayside. These measurements are consistent with an absence of atmosphere. P…
SpeCT: A state-of-the-art tool to calculate correlated-k tables and continua of CO-HO-N gas mixtures
G. Chaverot, M. Turbet, H. Tran +4
A key challenge in modeling (exo)planetary atmospheres lies in generating extensive opacity datasets that cover the wide variety of possible atmospheric composition, pressure, and…
Radial velocity homogeneous analysis of M dwarfs observed with HARPS. II. Detection limits and planetary occurrence statistics
L. Mignon, X. Delfosse, N. Meunier +13
We re-determine planetary occurrences around M dwarfs using 20 years of observations from HARPS on 197 targets. The first aim of this study is to propose more precise occurrence ra…
The Role of Atmospheric Composition in Defining the Habitable Zone Limits and Supporting E. coli Growth
Asena Kuzucan, Emeline Bolmont, Guillaume Chaverot +4
Studying exoplanet atmospheres is essential for assessing their potential to host liquid water and their capacity to support life (their habitability). Each atmosphere uniquely inf…
Resilience of Snowball Earth to Stochastic Events
Guillaume Chaverot, Andrea Zorzi, Xuesong Ding +6
Earth went through at least two periods of global glaciation (i.e., ``Snowball Earth'' states) during the Neoproterozoic, the shortest of which (the Marinoan) may not have lasted s…
The CUISINES Framework for Conducting Exoplanet Model Intercomparison Projects, Version 1.0
Linda E. Sohl, Thomas J. Fauchez, Shawn Domagal-Goldman +10
As JWST begins to return observations, it is more important than ever that exoplanet climate models can consistently and correctly predict the observability of exoplanets, retrieva…
Discovery of a cold giant planet and mass measurement of a hot super-Earth in the multi-planetary system WASP-132
N. Grieves, F. Bouchy, D. J. Armstrong +25
Hot Jupiters generally do not have nearby planet companions, as they may have cleared out other planets during their inward migration from more distant orbits. This gives evidence…
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…
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…
Three long period transiting giant planets from TESS
Rafael Brahm, Solène Ulmer-Moll, Melissa J. Hobson +52
We report the discovery and orbital characterization of three new transiting warm giant planets. These systems were initially identified as presenting single transit events in the…
The CORALIE survey for southern extrasolar planets XIX. Brown dwarfs and stellar companions unveiled by radial velocity and astrometry
D. Barbato, D. Ségransan, S. Udry +17
A historical planet-search on a sample of 1647 nearby southern main sequence stars has been ongoing since 1998 with the CORALIE spectrograph at La Silla Observatory, with a backup…
Transmission spectroscopy of the ultra-hot Jupiter MASCARA-4 b: Disentangling the hydrostatic and exospheric regimes of ultra-hot Jupiters
Yapeng Zhang, Ignas A. G. Snellen, Aurélien Wyttenbach +11
Ultra-hot Jupiters (UHJs), rendering the hottest planetary atmospheres, offer great opportunities of detailed characterisation with high-resolution spectroscopy. MASCARA-4 b is a r…
Two long-period transiting exoplanets on eccentric orbits: NGTS-20 b (TOI-5152 b) and TOI-5153 b
S. Ulmer-Moll, M. Lendl, S. Gill +50
Long-period transiting planets provide the opportunity to better understand the formation and evolution of planetary systems. Their atmospheric properties remain largely unaltered…
How does the background atmosphere affect the onset of the runaway greenhouse ?
G. Chaverot, M. Turbet, E. Bolmont +1
As the insolation of an Earth-like (exo)planet with a large amount of water increases, its surface and atmospheric temperatures also increase, eventually leading to a catastrophic…
Day-night cloud asymmetry prevents early oceans on Venus but not on Earth
Martin Turbet, Emeline Bolmont, Guillaume Chaverot +3
Earth has had oceans for nearly four billion years and Mars had lakes and rivers 3.5-3.8 billion years ago. However, it is still unknown whether water has ever condensed on the sur…
TRAPPIST Habitable Atmosphere Intercomparison (THAI) workshop report
