WDS 15467-4314 I 1276 (HD 140690) : NOTES

discov_num	notes	refcode
I 1276	HIP 77282. See Allen et al. (2000) for information on metallicity,	AlC2000
	age, galactic orbital parameters, etc.
	G5V dwarf at 47 pc. The WDS notes its resolution in 1926 by Innes at	I__1948a
	0.3" and the last measure in 1935. The separation corresponds to an	B__1947
	orbital period of 50 yr. Yet the system was not resolved by Hipparcos
	in 1991.25 and by speckle in 2001.56, 2008.54, and 2012.18. Nordstrom	Msn2012x
	et al. (2004) found only a marginal variability of RV during 8 yr.
	The binarity is thus questionable. Possibly a "ghost" binary, but not	Tok2012b
	"X" coded yet.
