| TOK 292 |
HIP 66676 (A) and HD 118735 (B, G6V, V=9.17) at 77" share common PM |
|
|
(although it is small, 58mas/y) which, together with photometry, |
|
|
indicates with high probability that it is a physical pair AB |
|
|
(Tokovinin & Lepine 2012). We targeted the secondary component B and |
Tok2015c |
|
found it to be a resolved triple. The faint star C, at 0".92 from B, |
|
|
is itself a close 0".16 pair Ca,Cb. Note that this is a region of the |
|
|
sky with very high stellar density, raising suspicion that the Ca,Cb |
|
|
pair might be a random background object. Re-observation of the triple |
|
|
in 2015 (to be published) shows, however, that it is physical because |
|
|
the center of C=(Ca,Cb) moves relative to B with a speed of 11mas/y |
|
|
(or 3km/s), compatible with the expected orbital motion of BC and much |
|
|
less than the system's PM of 58mas/y. The estimated period of Ca,Cb is |
|
|
~30 years, the period of BC is ~300 years. |
