WDS 16329+0315 DSG 7 Aa,Ab (HD 149162) : NOTES
 
 
discov_num notes refcode
GC 22255 Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Johnson & Mayor (1986). The use of the orbital elements derived by Jhn1986
Latham et al. (1992) produces a poorer fit. Lat1992
DSG 7 Horch et al. (2015) refer to the 280mas pair as AB; however, the B
component has already been assigned to the wide CPM companion of
Lepine (2007). Since they refer to the 15mas as Aa,Ab the wide DSG Lep2007
pair is assigned components Aa and Ac.
Aa,Ab: For the Horch et al. combined solution, spectroscopic elements Lat2002
are fixed to those of Latham et al. (2002). Assigned spectral types
for Aa, Ab, and Ac are K1V, K6V, and M5V; derived masses for Aa and Ab
are 0.77 and 0.64 Msun. Hor2015
Teff : A = 5252 K, B = 3400 K, C = 5500 K. Cab2018b
Mass (\msun) : Aa = 0.77, Ab = 0.64, Ac = 0.15, B = 0.40, C = 0.54.
