discov_num notes refcode
BNU 9 4 UMi. A spectroscopic binary, P = 605.8d, now resolved.
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Scarfe (1971). Scf1971
1984.2791: Halbwachs (1981) predicts an angular separation of about HJL1981
0".03 and the system appears to be at the limit of resolution of the
6-m telescope. Bnu1986
Ren & Fu (2013) calculated an astrometric orbit, combining Hipparcos Ren2013
Intermediate Astrometric Data with spectroscopic elements by
Scarfe (1971). Scf1971
