WDS 15245+3723 STFA 28 AB (Alkalurops) : NOTES
 
 
discov_num notes refcode
CHR 181 Aa,Ab: mu 1 Boo = 51 Boo A = Alkalurops. SB, P=298.75d.
More speckle observations are needed to confirm preliminary orbit.
Aa,Ab: Calculated mass sum is 3.24 +/- 0.23 Msun. Absorption lines too
broad and blended for RV measurements. Mut2010b
Aa,Ab: Orbital elements provided in Guerrero et al. (2021) match Gur2021
measures and previous orbits of STF1938Ba,Bb. The orbit is therefore
attributed to STF1938Ba,Bb in ORB6.
STF1938 Ba,Bb: mu 2 Boo = 51 Boo B.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
STFA 28 AB: HJL 221. HJL1986
AB: H 6 17. STF1938Ba,Bb: H 1 17. MEv2010
AB: SHY 275. Bayesian analysis by Shaya & Olling (2011) indicates very
high (near 100%) probability pair is physical. Shy2011
AB: Kiyaeva et al. (2014) find probably significant differences in the
elemental abundances of the Aa,Ab and Ba,Bb subsystems, and suggest
this quadruple is instead a close passage of two separate binaries. Kiy2014
