“TRAPPIST-1 e is widely regarded as one of the single most promising potentially habitable exoplanets known. It orbits TRAPPIST-1, an ultracool M8V red dwarf located about 41 light-years from Earth, and is one of seven roughly Earth-sized planets in the system. TRAPPIST-1 e has a radius of about 0.92 Earth radii and a mass of about 0.69 Earth masses, and it has been confirmed to be rocky with a density consistent with an iron-and-rock…”
List of potentially habitable exoplanets · TRAPPIST-1 e parameters
“Recent James Webb Space Telescope observations have begun to constrain the atmosphere of TRAPPIST-1 e directly. The JWST-TST DREAMS program reported the first NIRSpec PRISM transmission spectra of TRAPPIST-1 e, revealing significant stellar contamination that varied between four visits. From these data, researchers can rule out cloudy, primary hydrogen-dominated atmospheres of roughly 80 percent or more H2 by volume at better than the…”
JWST-TST DREAMS: Secondary Atmosphere Constraints for the Habitable Zone Planet TRAPPIST-1 e · Atmospheric constraints from NIRSpec PRISM
“A central challenge in interpreting TRAPPIST-1 e's JWST spectra is stellar contamination: because a potential atmosphere can only be observed through starlight, the host red dwarf's spots and faculae imprint signals that mimic or mask planetary absorption features. The DREAMS team mitigated this by exploiting repeated visits, reasoning that anything consistent between visits is most likely the planet, while signals that vary between…”
JWST-TST DREAMS: Secondary Atmosphere Constraints for the Habitable Zone Planet TRAPPIST-1 e · Stellar contamination and remaining scenarios
“Scientists involved in the JWST study framed TRAPPIST-1 e as a continuing frontrunner among habitable-zone planets. The core question, as researcher Ana Glidden put it, is whether different atmospheric scenarios can be constrained and whether those scenarios still allow for liquid water at the surface. Sara Seager emphasized the planet's promise, stating that TRAPPIST-1 e remains one of the most compelling habitable-zone planets and…”
