Tomo-e Gozen obtained single-chord high-cadence (2 fps) photometry data of a stellar occultation by a Kuiper Belt object Quaoar. No indication of atmospheric refraction was detected, putting a strict upper limit on the pressure of a methane atmosphere which implies the absence of a ~10 nbar-level global methane atmosphere on Quaoar’s surface.
