HO 581 Noted as a spectroscopic binary by Griffin. Grf1977a
One star, probably the primary, is SB1, P = 155.0 d; Hei1981e
#1187 in Batten et al. Bte1989
Muller (1953) corrected an error in the semi-major axis by Mlr1953a
Van Biesbroeck. VBs1927b
Martin et al. (1998) derive component masses 1.304 +/- 0.187 and
1.107 +/- 0.172 Msun. Mig1998
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 2.94 +/- 1.61, 2.07, and 0.88 Msun, respectively. Mlk2012
Astroseismic orbit analysis results in masses of 0.99 +/- 0.01 \msun XXX2018c
for A. 0.767 +/- 0.006 \msun for Ba and 0.66 +/- 0.01 \msun for Bb.
The orbital parallax is 21.9 +/- 0.2 mas.
