Stellar Parameters for Trappist-1 [PDF]
The Astrophysical Journal, 2018 Abstract TRAPPIST-1 is an ultracool dwarf star transited by seven Earth-sized planets, for which thorough characterization of atmospheric properties, surface conditions encompassing habitability, and internal compositions is possible with current and next-generation telescopes.

On the XUV Luminosity Evolution of TRAPPIST-1 [PDF]
The Astrophysical Journal, 2020 Abstract We model the long-term X-ray and ultraviolet (XUV) luminosity of TRAPPIST-1 to constrain the evolving high-energy radiation environment experienced by its planetary system. Using a Markov Chain Monte Carlo (MCMC) method, we derive probabilistic constraints for TRAPPIST-1's stellar and XUV evolution that account for observational

Bistability of the Atmospheric Circulation on TRAPPIST-1e
The Planetary Science Journal, 2022 Abstract Using a 3D general circulation model, we demonstrate that a confirmed rocky exoplanet and a primary observational target, TRAPPIST-1e presents an interesting case of climate bistability. We find that the atmospheric circulation on TRAPPIST-1e can exist in two distinct regimes for a 1 bar nitrogen-dominated atmosphere.

The Carbon-deficient Evolution of TRAPPIST-1c
The Astrophysical Journal, 2023 Abstract Transiting planets orbiting M dwarfs provide the best opportunity to study the atmospheres of rocky planets with current facilities. As JWST enters its second year of science operations, an important initial endeavor is to determine whether these rocky planets have atmospheres at all.

A study of Io’s sodium jets with the TRAPPIST telescopes
Astronomy & Astrophysics, 2023 Io is the most volcanically active body in the Solar System. This volcanic activity results in the ejection of material into Io’s atmosphere, which may then escape from the atmosphere to form various structures in the Jovian magnetosphere, including the plasma torus and clouds of neutral particles.
