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). |
