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 |
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. |
