discov_num notes refcode
BLA 12 Aa,Ab: omi And = 1 And. Spectrum composite: B6IIIpe+A2p.
There appear to be both short and long period light variations.
Zhuchkov et al. (2010) generated a new orbital solution based on Zhu2010
published astrometry and new spectroscopic data.
WRH 37 AB: P = 68.6y, a = 0.277", motion retrograde. B has been reported
to be a double-lined spectroscopic binary, P = 33.01d.
Orbital elements by Olevic & Cvetkovic (2006) for SB: Ole2006a
P = 33.01 +/- 0.02 d, Tper = 2446925.3 +/- 0.2, e = 0.24 +/- 0.01,
omega = 226.2 +/- 2.3deg, a sin i = 0.161 +/- 0.003 and
0.211 +/- 0.002 au, M sin3i = 3.74 +/- 0.05 and 2.86 +/- 0.05 Msun.
This component was first reported in McAlister & Hendry (1982) for McA1982b
1976.61, after which earlier French data were reprocessed to yield the
1975 measures.
Zhuchkov et al. (2010) generated a new orbital solution based on Zhu2010
published astrometry, new 6m speckle data, and new radial velocities.
LSC 104.
