WDS 06377+1624 BUP 90 AB : NOTES

discov_num	notes	refcode
BUP 90	gam Gem = 24 Cen = Alhena. H V 71. Elements P, T, e, and the longitude	Bey1967
	of periastron are from a spectroscopic orbit. Beardsley's data are
	inconsistent; the values of a, i, and the node given here approximate
	his ABFG most closely.
	See Baize & Petit (1989) catalog of doubles with variable component.	Baz1989d
gam Gem	Aa,Ab: Combined astrometric/spectroscopic solution. Fekel & Tomkin	Kpr1987b
	(1993) derive a spectroscopic period of 4614.0 +/- 0.7 days, as well	Fek1993
	as an approximate magnitude difference of 6.0 +/- 0.5 mag in V.
	An additional spectroscopic solution by Scholz et al. (1997) yielded a	Slz1997
	period of 4614.51 +/- 0.47; Lehmann et al. (2002) found a similar	Leh2002
	period and also looked for short-period variations.
OCC 9011	Aa,Ab: Drummond (2014) resolves the Aa,Ab pair, previously detected
	only by occultation. Setting scale of the astrometric/spectroscopic
	orbit, and combining with the van Leeuwen (2007) Hipparcos parallax,
	he derives component masses 3.4 +/- 0.8 and 1.4 +/- 0.3 Msun.	Dru2014
	Intensity Interferometer Limb-darkened diameter 1.39 +/- 0.09 mas.	HBr1974
