Chemical Fingerprints of M Dwarfs: High-Resolution Spectroscopy on 31 M Dwarfs with SPIRou

Farbod Jahandar, René Doyon, Étienne Artigau +10

We extend the methodology introduced by Jahandar et al. (2024) to determine the effective temperature and chemical abundances of 31 slowly-rotating solar neighborhood M dwarfs (M1-…

JWST/NIRISS reveals the water-rich "steam world" atmosphere of GJ 9827 d

Caroline Piaulet-Ghorayeb, Bjorn Benneke, Michael Radica +30

With sizable volatile envelopes but smaller radii than the solar system ice giants, sub-Neptunes have been revealed as one of the most common types of planet in the galaxy. While t…

Transmission Spectroscopy of the Habitable Zone Exoplanet LHS 1140 b with JWST/NIRISS

Charles Cadieux, René Doyon, Ryan J. MacDonald +20

LHS 1140 b is the second-closest temperate transiting planet to the Earth with an equilibrium temperature low enough to support surface liquid water. At 1.7300.025 R,…

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…
