WDS 23393+4543 CHR 149 Ba,Bb (HD 222326) : NOTES
 
 
discov_num notes refcode
CHR 149 1986.8914: This "prediscovery" confirmation was found by reexamination
of archival data. McA1990
Balega et al. (2004) notes that it is the B component of A 643, not Bag2004
the A component, which is comprised of the CHR 149 pair. The component
designation has been changed from Aa,Ab to Ba,Bb accordingly.
Zhuchkov et al. (2008) give combined spectroscopic/astrometric orbits Zhu2008
for both wide and close pair. Spectral types for A, Ba, and Bb are
determined as G0III, F3III, and sdO-BVIII, respectively. Magnitudes
(assuming an integrated system magnitude of 7.63) are 8.53 +/- 0.03,
8.66 +/- 0.04, and 9.51 +/- 0.05, while indiviual masses are estimated
at 1.3 +/- 0.3, 1.3 +/- 0.3, and 0.7 +/- 0.4 Msun.
