WDS 12095-1151 STF 1604 AB (HD 105590) : NOTES
 
 
discov_num notes refcode
STF1604 AB: Mt. Wilson spectral types are G2 and K8. A is a spectroscopic
binary, and slightly variable. Large relative proper motion, coupled
with the fact that the C component is brighter than B, has led to some
confusion in identification of components.
AB: NLTT 29769/29772 Chm2004
HIP 59272. Tok2011a
