8296 Miyama           Discovered 1993 Jan. 13 by K. Endate and K. Watanabe at Kitami.
Named in honor of Shoken M. Miyama (b. 1951), Japanese astrophysicist working mainly on star and planet formation. He was the principal investigator on the observation team that first detected the protoplanetary disk around a single star using the Nobeyama radio telescope. He was the first director of the public relations center of the National Astronomical Observatory of Japan and since 1996 has been the executive vice-director.
