discov_num notes refcode
D 15 Errors for orbit of Alzner (2007) provided by author (private comm.) Alz2007
With the Hipparcos parallax of 36.59 +/- 2.13 mas, the Alzner solution
yields a mass sum of 1.31Msun, which matches well a pair of K5 main
sequence stars.
Additional notes may be found in Duruy (1944) and Dur1944d
Worley (1956). Wor1956b
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.27 +/- 0.16, 1.52, and 0.65 Msun, respectively. Mlk2012
