CHR 125 Aa,Ab: Pleione, 28 Tau = BU Tau. Shell star and suspected long-period
spectroscopic binary (Hoffleit 1982) . Pleiades cluster member. Hof1982
Frequently unresolved, probably due to large Delta m. Msn1993b
For their measure, Roberts et al. reports that the "The close
proximity of the two star's PSFs prevented accurate measurement of the
astrometry and photometry." Rbr2007
Aa,Ab: Observed 3 times 1987-1991 (all observations noted as weak), Rbr2007
then unresolved until a 2002 (0.24") measure at 900nm Hrt2009
RBR 4 AF: 2002.0924: PA is measured in zenith mode. If data collected in
equatorial mode, PA = 119. Confirmation of the pair should establish
the correct value for theta. Rbr2007
