WDS 10435+4612 SMA 75 BP : NOTES
 
 
discov_num notes refcode
SMA 75 B is BD+46@1658. B is a spectroscopic binary.
AB: NLTT 25147/25160 Chm2004
AB: HJL 130. HJL1986
AB: SHY 216. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
MET 7 BE and BF: Primary of 10440+4612 MET 7AB and AC same as B component
of 10435+4612 SMA 75AB; systems merged.
Based on proximity, Metchev & Hillenbrand (2004) say the BE pair is Met2004b
probably physical.
