Constraints on the possible atmospheres on TRAPPIST-1 b: insights from 3D climate modeling

Alice Maurel, Martin Turbet, Elsa Ducrot +13

JWST observations of the secondary eclipse of TRAPPIST-1 b at 12.8 and 15 microns revealed a very bright dayside. These measurements are consistent with an absence of atmosphere. P…
