discov_num notes refcode
BU 1163 The system is also detected as a spectroscopic binary. B__1951a
Only elements P, T, and a have been amended by Starikova (1978) from Sta1978c
the orbit of van den Bos (1961). B__1961e
This system underwent periastron in late 1988, an event now covered by
speckle observations. Hrt1992b
A combined visual-spectroscopic orbit by Morbey (1975) gives almost Mrb1975
the same elements, but in the representation of position angles Sod1999
Soderhjelm's elements are preferable.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 2.59 +/- 0.41, 2.74, and 1.30 Msun, respectively. Mlk2012
