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 |
