A 2413 Component variable? Hln1963
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
According to Scardia et al. (2001), this orbit is now well defined and Sca2001d
will certainly change little in the future; only the period is still
slightly uncertain. The Hipparcos parallax is 0".02012 +/- 0.00150.
This gives a mass sum of 2.1 Msun +/- 29%, agreeing very well with
expected values for a system of type G0. Compared to the orbit
calculated by Scardia in 1980, the total mass of the system, whose Sca1980e
uncertainty was then 55%, is now much better defined. The dynamical
parallax is 0".0193, well in agreement with the measured parallax.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 1.64 +/- 0.52, 2.04, and 1.05 Msun, respectively. Mlk2012
