discov_num notes refcode
BSO 12 AB + TOK 410Ba,Bb: HIP 79980 and HIP 79979 form a 23" CPM pair AB
where the F6III primary is slightly evolved, while the G1/G2 secondary
is closer to the main sequence, but still above it. The Hipparcos
parallax of B, -4.7mas, is obviously wrong, so we assume the parallax
of the primary, 20.7mas. The RV(B) is variable (GCS), and we resolve
it into a 40mas pair with an estimated period on the order of 1yr. The
pair moved by 10deg in a month. Binary motion is the likely cause of
the incorrect Hipparcos parallax. Tok2015c
