Agricultural Missionaries: The Trappists and French Colonial Policy under the July Monarchy

Catholic Historical Review, 2020
:In the 1840s, the July Monarchy enlisted the Trappists to develop model farms in Algeria and Martinique. The July Monarchy wanted to remedy lackluster agricultural development in Algeria and to support the Martinique economy after emancipation.

Strict Limits on Potential Secondary Atmospheres on the Temperate Rocky Exo-Earth TRAPPIST-1 d

Astrophysical Journal
The nearby TRAPPIST-1 system, with its seven small rocky planets orbiting a late-type M8 star, offers an unprecedented opportunity to search for secondary atmospheres on temperate terrestrial worlds. In particular, the 0.8 R⊕TRAPPIST-1 d lies at the edge

JWST-TST DREAMS: NIRSpec/PRISM Transmission Spectroscopy of the Habitable Zone Planet TRAPPIST-1 e

Astrophysical Journal Letters
TRAPPIST-1 e is one of the very few rocky exoplanets that is both amenable to atmospheric characterization and resides in the habitable zone of its star—located at a distance from its star such that it might, with the right atmosphere, sustain liquid ...

JWST-TST DREAMS: Secondary Atmosphere Constraints for the Habitable Zone Planet TRAPPIST-1 e

Astrophysical Journal Letters
The TRAPPIST-1 system offers one of the best opportunities to characterize temperate terrestrial planets beyond our own solar system. Within the TRAPPIST-1 system, planet e stands out as highly likely to sustain surface liquid water if it possesses an ...

Uncertainties in the Inference of Internal Structure: The Case of TRAPPIST-1 f

Astrophysical Journal
We use the TRAPPIST-1 system as a model observation of Earth-like planets. The densities of these planets being 1%–10% less than the Earth suggest that the outer planets may host significant hydrospheres. We explore the uncertainty in water mass fraction

Tracing the inner edge of the habitable zone with sulfur chemistry

Science Advances
The circumstellar liquid-water habitable zone guides our search for potentially inhabited exoplanets but remains observationally untested. We show that the inner edge of the habitable zone can now be mapped among exoplanets using their lack of surface ...

Effects of Transient Stellar Emissions on Planetary Climates of Tidally Locked Exo-Earths

Astronomical Journal
Space weather events in exoplanetary environments sourced from transient host star emissions, including stellar flares, coronal mass ejections, and stellar proton events, can substantially influence a planet's habitability and atmospheric evolution ...
