WOR 2 Tamazian et al. derive a dynamical mass sum of 1.40 +/- 0.25 Msun Tam2005
and classify the stars as K6-7V and M0V. Absolute magnitudes of
the two components are estimated at +8.0 and +8.6, leading to
individual masses of 0.65 and 0.61 Msun, in good agreement with
the dynamical mass sum.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.46 +/- 0.20, 1.25, and 0.55 Msun, respectively. Mlk2012
