STF1102 AB: HJL 84. HJL1986
AD: HJL1048. HJL1986
AD: SHY 191. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
AD: Halbwachs et al. (2012): SB1 orbit of D, P=2708.2d, e=0.716, HJL2012b
K1=4.93, V0=-2.38 => M2min=0.27. D co-moving with HIP 33818 at 6.0pc. Tok2014d
BD: HJL1049. HJL1986
TOK 392 Da,Db: This is a quadruple system. The 7".7 AB pair (STF 1102) is
HIP 36485, the CPM component D = HIP 36497 = HD 59450 is located at
112" from it, while the WDS components C and E are optical. The
physical nature of AD is established by common PM, distance, and RV.
D is a known SB1 with P=2708d=7.4yr (Halbwachs et al. 2012, MNRAS 422,
14) and an estimated semi-major axis of 93mas, also an acceleration
binary. We resolved the Da,Db pair at 0".11, dI=2.6. The minimum mass
of Db derived from its SB orbit is 0.27 Msun, while we estimate the
masses of Da and Db as 1.05 and 0.6 Msun from their luminosity. A
previous non-resolution of D is reported in INT4; it was also RAO2015
unresolved with Robo-AO (Riddle et al. 2015). Tok2015c
