WDS 15183+2650 STF 1932 AB (HD 136176) : NOTES
 
 
discov_num notes refcode
STF1932 There is evidence of light-variability in the system.
A subsystem of 30 to 50 yr period, formerly suspected from visual
data, is not supported by the more recent observations.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Spectral types and masses of components assigned by ten Brummelaar et TtB2000
al., based on adaptive optics observations.
AB: Check astrometric orbit of Ba,Bb. Interferometric observations do
not support 30-y or 50-y astrometric subsystem. Tok2014d
