KER 2 Aa,Ab: RED 12. 2MASSW J1146345+223053
HST WFPC2 observations by Reid et al. (2001). Paper includes mass and Red2001
age estimates, as well as discussion of L dwarf binary frequency and
semimajor axis distribution.
ALP 17 AB: Observed in I-band at WIYN in February 2003, but companion not
detected. Ruled out as brown dwarf companion following further
IRTF/NSFCam H- and methane-band photometry in April 2004. AlP2007
KER 2 Primary is an L3V brown dwarf; LRIS spectrum shows other component is
a background star of much earlier type. Kir1999
