Finsen called attention to quasi-periodic residuals in position | ||
angle which neither of the alternative orbits explains. | ||
Illustrative solutions with useable astrometric mass-ratios. Short-P | ||
solution marginally better, but indeterminate with strong element- | ||
correlations. Probably giant primary, more speckle-data needed. | Sod1999 | |
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic | ||
masses of 5.24 +/- 0.83, 3.26, and 1.58 Msun, respectively. | Mlk2012 | |
Docobo & Andrade (2013) derive a dynamical parallax of 22.71 +/- 0.69 | ||
mas and component masses 1.78 +/- 0.21 and 1.33 +/- 0.16 Msun. See | ||
paper for extensive notes on this system. | Doc2013d |
