Allers et al. derive spectral types L3 +/- 0.5 and L5 +/- 1 for the |
Alr2010 |
|
primary and secondary, respectively; age of the system is roughly |
|
|
100 Myr. Based on luminosities and age, masses are expected to be |
|
|
roughly 0.029 +/- 0.006 and 0.021 +0.006/-0.009 Msun. Distance is |
|
|
about 56 +/- 16pc, and the orbital period is estimated at ~400 years. |
