BU 552 Hyad (vB 124). Wor1963a
The primary is 143d SB (Griffin et al. 1985). Grf1985b
The spectroscopic system of Griffin et al. would be too close for us
to resolve by speckle interferometry. Msn1993a
A: Ren & Fu (2013) calculated an astrometric orbit, combining
Hipparcos Intermediate Astrometric Data with spectroscopic elements by
Turner et al. (1986). They derived component masses 1.42 and 0.55 Msun TrD1986
and an estimated semimajor axis of 15.67 mas. Ren2013
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 2.67 +/- 1.47, 2.30, and 1.00 Msun, respectively. Mlk2012
A faint component (about mag. 13, 45") is unobserved since 1906; its
physical nature is unknown.
