MCA 55 Aa,Ab: bet 1 Cyg = bet Cyg A = Albireo = 6 Cyg A. Resolved in 1976 by
speckle interferometry and has also been seen visually. McA1982b
See the discussion of colors and magnitudes of this composite spectrum
system by Bonneau & Foy (1980). Bnu1980a
1977.4816: This object was incorrectly attributed to the system ADS
12540 = STF 43 by McAlister (1979). McA1979b
McAlister & Hendry (1982) also note a distant companion. McA1982b
1983.4904: The distant companion reported by McAlister & Hendry (1982) McA1982b
would be located beyond our 0".371 ACF window. Bag1984a
Spectral types of primary and secondary assigned by ten Brummelaar et
al., based on adaptive optics observations. TtB2000
1998.657: Absolute quadrant determined by triple-correlation technique Pru2002b
Aa,Ac: Malkov et al. (2012) derive dynamical and spectroscopic masses
50.66 +/- 15.18 and 22.40 Msun, respectively. Mlk2012
Mk III Limb-darkened diameter 4.834 +/- 0.048 mas. MkT2003
NPOI Limb-darkened diameter 4.904 +/- 0.035 mas,
R = 58.69 (+2.83-3.12 ) \rsun, Teff = 4860 +/- 20 K,
L = 1734. +/- 174. \lsun. NOI2023
STFA 43 STTA183.
AB: B is BD+27@3411, spectrum B8V.
The physicality of this wide pair has been discussed by Griffin. Grf1999b
1995.559: Absolute quadrant determined by triple-correlation technique Pru2002b
AB: H 5 5. MEv2010
While A & B may share a common origin, it seems virtually certain that Bst2018
are not physically associated with each other. The parallax of A is
9.95+/-0.60 mas while B is 8.38+/-0.17 mas.
RBR 12 Ba,Bb: First resolved in 2002, after multiple non-detections, this is Rbr2007
now thought to be a measure of the known Aa,Ab pair MCA 55 with a much Rbr2013a
larger than expected position angle error.
