WDS 06573-3530 I 65 (HD 51825) : NOTES
 
 
discov_num notes refcode
I 65 1997.1172: Despite nearly a century of visual observations and a grade
1 orbit in the orbit catalog of Worley & Heintz (1983), this is Wor1983
apparently the first speckle measure of this system. Hor1997
A few more speckle observations will strengthen orbit considerably.
Martin et al. (1998) derive component masses 1.614 +/- 0.211 and
1.256 +/- 0.195 Msun. Mig1998
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 2.53 +/- 0.16, 2.11, and 1.19 Msun, respectively. Mlk2012
