MCA 16 Aa,Ab: tau Tau = 94 Tau. Occultation binary and short-period SB.
Hough suspected duplicity due to a slow occultation. Finally resolved
by McAlister in 1980. McA1983
1983.9337, 1983.9391: Interferometric observations are incompatible Jef1963
with the large delta m reported by Jeffers et al. (1963). Bnu1984
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 12.44 +/- 4.14, 7.48, and 6.92 Msun, respectively. Mlk2012
Uniform disk diameter 0.220 +/- 0.016 mas,
Limb darkened diameter 0.226 +/- 0.016 mas,
Teff = 18500 +/- 800 K based on LDD.
Radius is 2.27 +/- 0.20 \rsun. CIA2019a
S 455 STTA 54 = H 6 7.
