Towards robust corrections for stellar contamination in JWST exoplanet transmission spectra

Thermal emission from the Earth-sized exoplanet TRAPPIST-1 b using JWST

AkaSci | Here is a graph from the paper that shows how the measured temp. of 503K implies a lack of atmosphere for exoplanet Trappist-1b. Top green curve: the 508K dayside temp predicted for zero heat redistribution. Blue curve: the measured 503K dayside temp. Orange curve: the predicted temp. with heat redistribution by an atmosphere. Last 2 curves: spectra from CO2 and O2+CO2 atmospheres. The MIRI 15 µm filter measurement lies on the blue curve. https:// arxiv.org/abs/2303.14849 # JWST # Trappist1 # exoplanet 7/n

TRAPPIST-1 b: We give it a one (M-dwarf) star review; it lacks atmosphere. ⭐ Webb found the dayside temperature of this rocky exoplanet to be about 450º F (227º C) — suggesting it has no significant atmosphere:
