Small motions with 3 or 6 yr periods in one of the components have |
|
|
been suspected, but from the positional and RV observations Heintz |
|
|
finds no evidence for them, and points out that the O-C residuals |
|
|
would be increased by the hypothetical body. |

|
|
(using their orbital elements and the revised Hipparcos parallax of |
