discov_num notes refcode
STTA108 AB and AC: Optical pairs, based on study of relative motion of the
components using the method of apparent motion parameters. Kiy2008
Primary is MN UMa, variable of BY Dra type. Tok2014d
KIR 3 AE. Data from 2MASS. Kirkpatrick et al. (2001) derive spectral types Kir2001a
G0V and L4.5V, determine is physical pair, separation ~2000 au.
STTA108 BD: Distances are 2083.6" in 1825, 2094.6" in 1910. D is BD+36@2170.
BOY 5 Ea,Eb: Originally listed as separate pair WDS 11124+3548, before
association with WDS 11125+3549 recognized.
Dupuy et al. (2014) find a total mass 0.095 +/- 0.003 Msun (99 +/- 3
Mjup), log age 8.87 +/- 0.08. Spectral types are L4.5 and L6. Dup2014
