BRG 18 |
This target, like BRG 23, gives conflicting information about whether |
|
|
the AB pair is physically bound. The brightness and color are fully |
|
|
consistent with B being an M3.5 companion to the M2.0 primary. |
|
|
Furthermore, the separation is only 0.2", and the whole field is |
|
|
otherwise empty. This indicates physical companionship. However, the |
|
|
deviation from the expectation of a background source is only 1.1 |
|
|
sigma, and the companion has moved 3.6 times closer to the background |
|
|
expectation than its original position where the motion has a 14 sigma |
|
|
confidence. This, by contrast, suggests a chance alignment. Since the |
|
|
magnitude of motion is not inconsistent with what could be expected |
|
|
for orbital motion of a real physical pair, we keep it as binary in |
|
|
our analysis, but we note that further observations will be necessary |
|
|
in order to resolve this issue satisfactorily. |
