JWST Reveals CH, CO, and HO in a Metal-rich Miscible Atmosphere on a Two-Earth-Radius Exoplanet
Björn Benneke, Pierre-Alexis Roy, Louis-Philippe Coulombe +28
Even though sub-Neptunes likely represent the most common outcome of planet formation, their natures remain poorly understood. In particular, planets near 1.5-2.5 often…
Muted Features in the JWST NIRISS Transmission Spectrum of Hot-Neptune LTT 9779 b
Michael Radica, Louis-Philippe Coulombe, Jake Taylor +13
The hot-Neptune desert is one of the most sparsely populated regions of the exoplanet parameter space, and atmosphere observations of its few residents can provide insights into ho…
Characterizing the Near-infrared Spectra of Flares from TRAPPIST-1 During JWST Transit Spectroscopy Observations
Ward S. Howard, Adam F. Kowalski, Laura Flagg +16
We present the first analysis of JWST near-infrared spectroscopy of stellar flares from TRAPPIST-1 during transits of rocky exoplanets. Four flares were observed from 0.6--2.8 m…
Water absorption in the transmission spectrum of the water-world candidate GJ9827d
Pierre-Alexis Roy, Björn Benneke, Caroline Piaulet +16
Recent work on the characterization of small exoplanets has allowed us to accumulate growing evidence that the sub-Neptunes with radii greater than often host H…
ATOCA: an algorithm to treat order contamination. Application to the NIRISS SOSS mode
Antoine Darveau-Bernier, Loïc Albert, Geert Jan Talens +20
After a successful launch, the James Webb Space Telescope is preparing to undertake one of its principal missions, the characterization of the atmospheres of exoplanets. The Single…
