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…

A New Spectral Library for Modeling the Surfaces of Hot, Rocky Exoplanets

Kimberly Paragas, Heather A. Knutson, Renyu Hu +7

JWST's MIRI LRS provides the first opportunity to spectroscopically characterize the surface compositions of close-in terrestrial exoplanets. Models for the bare-rock spectra of th…

Atmospheric Retrievals of the Young Giant Planet ROXs 42B b from Low- and High-Resolution Spectroscopy

Julie Inglis, Nicole L. Wallack, Jerry W. Xuan +7

Previous attempts have been made to characterize the atmospheres of directly imaged planets at low-resolution (R10s-100s), but the presence of clouds has often led to degener…

A roadmap for the atmospheric characterization of terrestrial exoplanets with JWST

TRAPPIST-1 JWST Community Initiative, :, Julien de Wit +80

Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominen…
