BLA 10 L 789-6. GJ 866. One of the nearest stars, proper motion +2340 +2270.
Leinert et al. (1990) derive a combined spectroscopic/interferometric/ Lei1990
photometric solution, yielding masses and temperatures, etc.
Adopted magnitude differences are as follows:
0.20 +/- 0.13 mag 845 nm
0.63 +/- 0.08 mag 1250 nm
0.63 +/- 0.06 mag 1650 nm
0.63 +/- 0.06 mag 2250 nm
0.63 +/- 0.10 mag 3800 nm
0.55 +/- 0.36 mag 4800 nm
Very low mass triple. AC pair is 3.8-day SB orbiting B component.
Combined spectroscopic/interferometric/parallax orbit given for AC,B
by Delfosse et al. (1999). Resulting masses are placed on M-L diagram. Del1999b
Combined solution from astrometry, spectroscopy, and parallax derived
by Segransan et al. (2000). Solution yields mass and orbital parallax Sgr2000
determination.
