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

As we enter a new era of using JWST to characterize exoplanet atmospheres, a top priority is defining observational needs and parameters in the search for life on an exoplanet. Alt…

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 f…

Potential Atmospheric Compositions of TRAPPIST-1 c constrained by JWST/MIRI Observations at 15 m

Andrew P. Lincowski, Victoria S. Meadows, Sebastian Zieba +13

The first JWST observations of TRAPPIST-1 c showed a secondary eclipse depth of 421+/-94 ppm at 15 um, which is consistent with a bare rock surface or a thin, O2-dominated, low CO2…
