WDS 14038-6022 RBT 1 Aa,Ab : NOTES
 
 
discov_num notes refcode
RBT 1 Aa,Ab: bet Cen = Hadar. Also, historically known as Agena. The IAU
sanctioned official name is Hadar. Measure of 1995.035 made by MAPPIT. Rbt1999
Interferometric data from SUSI are combined with spectroscopic data to
yield orbital parameters, masses, and distance. Dvs2005
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 29.50 +/- 5.38, 23.82, 12.02 Msun, respectively. Mlk2012
VOU 31 AB: Spectroscopic and interferometric measures indicate a multiple
system.
