RAO 39 RoboAO finds 2 companions - Optical? 2MASS: B at 32.4" 145.3d, below RAO2015
the MS, optical? Tokovinin & Lepine (2012) miss AB but list an optical Tok2012c
companion at 1733". Tok2014d
AB: A is SB2 with P = 26.2 days (Griffin & Suchkov 2003). The tertiary Grf2003
companion B at 2".8 did not move substantially in a year since its
discovery by Riddle et al. (2015), but the PM of the main component A RAO2015
is small and the astrometry is not conclusive. B is located below the
MS on the CMD, although still within the errors of its photometry.
Considering the small field crowding, we count B as likely physical. Rbr2015d
