The B component was resolved at Palomar (0.580"). Genet et al. (2013)
detect a wobble in the motion of AB, with P~107y, alpha~0.18"
suggesting M2~0.5 Msun
Tok2014d
AB: known binary, which shows apparently a non-Keplerian motion. Rica
Romero & Zirm (2014) proposed that the motion was caused by an unseen
RMR2014c
companion and calculated an astrometric orbit for it with P = 107 yr,
eccentricity 0.61, and photocenter semimajor axis 0".179. Our
observations were able to resolve the predicted subsystem Aa,Ab. For
the time of our observations the orbit predicts a companion position
angle of 43.3 deg, in excellent agreement with the position angle of
44 +/- 1.3 deg measured here. The ratio of the predicted displacement
to the measured separation of 0".50 is r = 0.32 = q/(1+q). Hence, the
mass ratio q = 0.47 (the contribution of the light from Ab to the
photo-center is neglected). The mass of Aa is estimated at 1.16 Msun
from its absolute magnitude, leading to 0.54 Msun for Ab. The absolute
magnitude of Ab corresponds to a smaller mass of 0.33 Msun. This
discrepancy, if confirmed, can be explained by Ab being a close pair
of M-dwarfs, as happens in other known multiple systems, e.g., in kap
Tok2013a
For (Tokovinin 2013).
