WDS 12560-1257 SJM 1 Aa,Ab : NOTES
 
 
discov_num notes refcode
SJM 1 Aa,Ab: Stone et al. (2016) resolve the primary of the late M dwarf
VHS J125601.92-125723.9, whose 8" companion was found to be an L-type
brown dwarf. (Gauza et al. 2015). Spectrophotometric distance Gza2015
estimates implied by the M7.5 spectral type of the primary yield a
distance of 17.1 +/- 2.5 pc. Kinematics are consistent with membership
in the AB Dor moving group. For an age ~300 Myr, the masses of these
two near-equal magnitude M7.5 stars are each 64.6 +0.8/-0.2 Mjup, and
the mass of the distant companion is 11.2 +9.7/-1.8 Msun. SJM2016
