discov_num notes refcode
STF2481 Mt. Wilson spectral type of A is G4.
A,BC triple solution. Sod1999
H 2 68 Bu_1906
SE 2 Mt. Wilson spectral type of BC is K0.
SE 2 is the np component of STF 2481 (van den Bos). B__1925a
The pair BC is 4.5" Nf star A (mag. 8.4, G5) and is in slow B__1960b
retrograde motion about it. The combined light of B and C is
slightly brighter than that of A; thus the quadrant of A,BC
(= STF 2481) is sometimes confused.
BC: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 2.04 +/- 0.45, 2.02, and 0.95 Msun, respectively. Mlk2012
TAR 4 DE: 3' south of ADS 12145. Heintz identifies this with HLM 17 Hei1990b
(aka ADS 12149).
