The Effects of M Star Age Dependent Ultraviolet Emission on Detecting and Interpreting Exoplanet Biosignatures
C. Evan Davis, Victoria S. Meadows, Evgenya L. Shkolnik +5
Given their abundance and observational advantages, M stars will arguably be the best candidates for characterizing and searching for biosignatures on terrestrial exoplanets in the…
Piercing through the Haze: Characterizing Titan-like terrestrial exoplanets with JWST
L. C. Mayorga, Jacob Lustig-Yaeger, Andrew P. Lincowski +5
The paper evaluates how well JWST can characterize Titan-like exoplanet atmospheres by testing retrieval methods on Cassini data and applying them to a hypothetical TRAPPIST-1 plan…
Coupled Photochemical-Climate Modeling of Plausible Tenuous Outgassed Atmospheres on the TRAPPIST-1 Planets
Megan Gialluca, Victoria Meadows, Andrew Lincowski +4
Available JWST observations TRAPPIST-1 system have suggested that several of the planets are likely airless, or possess a very tenuous atmosphere. However, the high atmospheric esc…
The Third Option: Color Phase Curves to Characterize the Atmospheres of Temperate Rocky Exoplanets
Drake Deming, Andrew Lincowski, Laura Kreidberg +6
Detecting and characterizing the atmospheres of rocky exoplanets has proven to be challenging for JWST. Transit spectroscopy of the TRAPPIST-1 planets has been impacted by the effe…
First JWST thermal phase curves of temperate terrestrial exoplanets reveal no thick atmosphere around TRAPPIST-1 b and c
Michaël Gillon, Elsa Ducrot, Taylor J. Bell +30
We report JWST/MIRI 15 m phase curves of TRAPPIST-1 b and c, revealing thermal emission consistent with their irradiation levels, assuming no efficient heat redistribution. We…
