WDS 07304+1352 STF 1102 AD : NOTES

discov_num	notes	refcode
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
