Astronomers have searched red dwarf star exoplanetary atmospheres, and the results haven't been hopeful. The first two planets orbiting TRAPPIST-1 have turned out to be airless super-mercurys, and now the sub-earth GJ 367 b shares the same fate. Astronomers used JWST to search for an atmosphere around the extremely dense metal planet and found nothing. The planet orbits so close to its star that the day side would be molten, destroying any volatiles it ever had.
