discov_num notes refcode
A 2145 Composite spectrum binary, classified G2III+A2V by Markowitz
(1969 Dissertation, Ohio State Univ.), who quotes delta m = 1.1.
It is not known which spectrum belongs to the visual primary.
Only elements P and T have been amended by Starikova (1977) from the Sta1977a
second orbit of Baize (1957). Baz1957a
1983.9371, 1983.9372: Interferometric observations are in disaccord Wor1983
with the 1957 orbital elements of Baize (see Worley & Heintz 1983). Bnu1984
1984.1861, 1984.2814, 1985.2053: The speckle interferometric
observations show that Finsen's orbit fails to describe the orbital Fin1977a
motion of this system. Bnu1986
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 13.28 +/- 8.31, 6.98, and 3.29 Msun, respectively. Mlk2012
