WDS 04317+1814 GHE 9 Aa,Ab : NOTES

discov_num	notes	refcode
HER 10	AB: Additional notes may be found in Herbig (1962).	Her1962
	XZ Tau.
GHE 9	Aa,Ab: Dodin et al. (2016) generated the following preliminary orbital
	elements: P = 155-256y, a = 27.2-37.2au, i <47deg, e = 0.29-0.64.	Dod2016
	Carrasco-Gonzalez et al. (2006) found a close companion to the Aa	CGo2006
	component at 7mm wavelength (~6deg, 0.09", dm 0.4 +/- 0.3 mag).
	However, subsequent observations by Forgan et al. (2014) and the ALMA	Fgn2014
	Partnership (2015) found no evidence of this additional component and	ALM2015
	concluded it was a false detection.
