SHY 297 HIP 85342 + HIP 85326.
AB + TOK 415Ba,Bb: HIP 85342 and HIP 85326 form a physical pair AB at
127" separation (common PM, RV, and parallax). The B component = HIP
85326 has a variable RV and an astrometric acceleration which could
hardly be produced by the 1" speckle companion Bb found here, owing to
its long estimated period of ~300yr. It seems that B is triple and the
whole system is quadruple. This companion Bb was not detected in the
previous speckle observations because it is red: dI = 2.4, dy = 4mag;
its color matches a dwarf star at the same distance as the system.
However, the field is crowded and the newly found companion could
still be optical. Tok2015c
AB: Tokovinin & Lepine (2012) miss B, but list companion at 1373", Tok2012c
likely optical. Tok2014d
