discov_num notes refcode
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
