Doolittle notes a 3rd star in the direction of B. 30" +/- distant, |
Doo1932A |
|
12th magnitude, 1919.8. |
|
|
CPM of the components suggests that this pair could be physical; |
|
|
however, since the relative motion of the components is larger than |
|
|
their proper motion, the question of whether they are physically bound |
|
|
remains open. |
