dmu is explained by the newly resolved 0".5 pair. Triple, with |
|
|
companion at 13".8 in 2MASS. This companion is measured with NICI as |
|
|
well at the same position, its colors matching a low-mass dwarf. |
|
|
Considering the low density of background stars, the companion is |
|
|
physical, although we cannot confirm it as CPM owing to the small PM |
|
|
of the main target. |
