The M3.0 equal-flux binary was first resolved by Janson et al. (2012), |
Jnn2012 |
|
and has seen significant orbital motion. Its parallactic distance of |
|
|
37.9 +/- 5.7 pc (Shkolnik et al. 2012 ApJ 758, 56) implies a physical |
|
|
separation of ~3-5 au. The expected orbital period is 10-20y. |
