WDS 01493+4754 STF 162 AB (HD 11031) : NOTES
 
 
discov_num notes refcode
CHR 4 Aa,Ab: Although this new component is indicated as Aa,Ab we have not
firmly established whether it is associated with the A or B component
of the wide pair. McA1987b
B is a spectroscopic binary. The system appears to be quintuple.
STF 162 AB: Rectilinear solutions by Zirm & Rica (2014) Zir2014b
and Genet et al. (2015). GnR2015a
Despite the linear solution, proper motion and parallax favor a Grv2020a
physical connection. Long period and/or high eccentricity possible.
