STF 677 AB: CfA: RV var? Can be a sub-system in A or B. Tok2014d
Now a 3 tier quadruple system since we resolved the secondary
component of the binary STF 677AB into a new 0".18 pair Ba,Bb and
confirmed that the Robo-AO tertiary C at 7" is physical. We find C to
be slightly below the MS, within errors. Although the relative motion
of AC is fast, it is not directed away from PM(A) as would be the case
for a distant background star; it is produced by the orbital motion of
the inner binary AB. The presence of an inner subsystem in the binary
AB was suspected previously from its variable RV (Nordstrom et al.
2004). The estimated masses of Ba and Bb, 0.98 and 0.65 Msun, Nrd2004
respectively, remove the discrepancy between the mass sum of 3.05 Msun
calculated for the AB system from its grade 4 orbit by Hartkopf et al. Hrt2008
(2008) and the expected mass sum. Although such discrepancies are not
uncommon for low-quality orbits, in this case it serves as an indirect
confirmation of Ba,Bb. Estimated period of Ba,Bb is ~20 yr. Rbr2015d
