BU 883 Hyad (vB 122).
Mass-sum calls for sp subsystem, but RV-ampl <1km/s according to
Griffin et al. (1988). Grf1988
AO photometric analysis by ten Brummelaar et al. (2000) includes mass
determination. TtB2000
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 2.58 +/- 0.49, 2.36, and 2.24 Msun, respectively. Mlk2012
Argument of periastron flipped for Sod1999 orbit since WDS refers to
fainter star as primary.
AB,C: Optical pair, based on study of relative motion of the
components using the method of apparent motion parameters. Kiy2008
AB,C: Rectilinear solution by Hurowitz et al. (2013). USN2013a
