FIN 317 |
Aa,Ab: FIN 317 is a close subsystem in the 2.9" AB pair HJ 4188. After |
|
|
discovery of Aa,Ab in 1951 at 0.116", Finsen (1951) was unable to |
Fin1951b |
|
resolve the star again on twelve occasions till 1968, except one other |
|
|
tentative measure in 1962. Yet the object was resolved by speckle in |
Fin1964a |
|
1989.94 at 0.144" and in 2006.18 at 0.123". Despite orbital period of |
|
|
∼50 yr estimated from projected separation, the sub-system was not |
|
|
detected in 3 runs at SOAR (2009-2012), while the wider pair AB was |
|
|
measured. This may be yet another case of erratic measures and |
|
|
non-resolutions. Possibly another "ghost" which isn't a real binary, |
Tok2012b |
|
but not "X" coded yet. |
