WDS 18186-1348 SNA 87HJ : NOTES
 
 
discov_num notes refcode
DCH 26 The AB pair is visible as SBA in spectroscopy, although no orbital
motion is detected (Sana et al. 2009), inagreement with the large Sna2009
separation, hence very long period. Five other faint companions are
detected in the NACO FOV. Sna2014
