Radar and Optical Simultaneous Observations of Faint Meteors
November 11th, 2020
The MU radar and Tomo-e Gozen detected 331 faint sporadic meteors simultaneously. The observations revealed a linear relationship between radar cross sections and optical brightness and confirmed that this collaboration is promising to investigate interplanetary dust in the vicinity of the Earth.
New Constraint on the Atmosphere of Quaoar from a Stellar Occultation
November 27th, 2019
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.
