The companion to 2MASS J13015919+4241160 is clearly inconsistent with |
|
|
a background contaminant, but the astrometry is also inconsistent with |
|
|
a simple orbital motion of B around A - for instance, the separation |
|
|
decreases from June 2008 to February 2009, but then increases again to |
|
|
June 2009. This could for instance imply that either A or B is a close |
|
|
unresolved binary, where the photo-center shifts on a shorter |
|
|
timescale than that of the AB orbit. |
