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. |
