BU 286 | 16 Sgr. A is a spectroscopic binary. | |
CHR 255 | Aa,Ab: Garmany et al. (1980 ApJ 242, 1063) observed a smoothly-varying | |
velocity indicating that the A component is probably a single-lined | ||
binary with a period of 11 d. | ||
Lindroos (1985) provided the classification of the B component and | Lnd1985 | |
determines a distance of 1.2 kpc. | Msn1998a | |
SNA 83 | 16 Sgr. SB. See discussion of system by Sana et al. 2014). | Sna2014 |
