WDS 21000+4004 KUI 103 AB (V1396 Cyg) : NOTES

discov_num	notes	refcode
KUI 103	V1396 Cyg.
	Astrometric orbit by Lippincott (1975), with only the semi-major axis	Lip1975
	derived from visual separations. The longitude of periastron has been
	reversed to correspond to the visual position angles.	Lip1975
	An observation by Tokovinin (1982) - 1981.370, 48.1 degrees, 0".377 -	Tok1982a
	was reduced improperly, so has been removed.	Tok1982b
	Visual primary is a BY Dra-type variable, and 3.3d SB2 (#1280 in
	Batten et al., 1989).	Bte1989
	Pourbaix gives combined solution for this resolved SB2, yielding	Pbx2000b
	orbital parallaxes and component masses.
	See Baize & Petit (1989) catalog of doubles with variable component.	Baz1989d
	GJ 815. In addition to the component that we resolve with AstraLux,
	which was previously known and has been studied over a long timescale
	(e.g. Lippincott 1975), the primary component of the resolved pair is	Lip1975
	a 3.3 day spectroscopic binary (Pourbaix 2000). Estimated age 30-300
	Myr; masses 0.58 +/- 0.05 and 0.26 +/- 0.09 Msun; a ~10.5 au.	Jnn2014
