WDS 08589+0829 DEL 2 : NOTES

discov_num	notes	refcode
DEL 2	G 41-14. A triple system with a close spectroscopic pair on a 7.6 day
	orbit, and one wider component which is reported at a separation of
	620 mas in Delfosse et al. (1999). Subsequently, an orbit has been	Del1999a
	determined for the wider pair (Hartkopf et al. 2012), with a period of	Hrt2012a
	5.66 years and a 424 mas angular semi-major axis. Using the estimated
	orbital elements to predict the location of the wider component in Jan
	2012 when the AstraLux image was taken, the predicted separation is
	~100 mas. This is in excellent agreement with what is seen in the
	AstraLux image, where the PSF is substantially extended, but not quite
	sufficiently to get a satisfactory binary fit.	Jnn2014
