BOY 10 Aa,Ab: 2MASSW J1728114+394859
Aa,Ab: Burgasser et al. (2011) derive spectral types of L5 and L6.5, Bug2011
masses 0.075 +/- 0.007 and 0.066 +/- 0.008 Msun, and effective
temperatures 1570 +/- 80 and 1340 +/- 70K.
Aa,Ab: Assuming a parallactic distance of 24.1 +/- 2.1 pc
(Vrba et al. 2004), Konopacky et al. (2010) derive a system mass of Vrb2004
0.15 +0.25/-0.04 Msun. Kon2010
ALP 22 AB: Physical companionship to this ultracool dwarf ruled out based on
I-J color, using I-band photometry taken at WIYN in August 2002. AlP2007
