WDS 22499+0044 ALR 1 : NOTES
 
 
discov_num notes refcode
ALR 1 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.
