LDS 905 AB: NLTT 19685/19684 Chm2004
CU Cnc and CV Cnc. This is a known quintuple system, as reported in,
e.g Delfosse et al. (1999) and Beuzit et al. (2004). Four of the Del1999a
components are resolved in two separate pairs (Aa,Ab and Ba,Bb) by Beu2004
AstraLux. The fifth component is unresolved in the images; this is an
eclipsing binary companion to the Aa component. Jnn2014
BEU 12 Aa,Ab: Estimated age 30-300 Myr; masses 0.20 +/- 0.09 and 0.04 +/-
0.03 Msun; a ~6.0 au. Jnn2014
DEL 1 Ba,Bb: Estimated age 30-300 Myr; masses 0.24 +/- 0.12 and 0.18 +/-
0.09 Msun; a ~10.6 au. Jnn2014

Chm2004 (Photometry, coordinates, and astrometry from rNLTT. Astrometry from early
Chm2004 versions of 2MASS and UCAC, with date given only as "circa 2000". Measures
Chm2004 identical to discovery observations - predominantly close pairs - were assumed
Chm2004 not new observations, so not included in WDS. Similar concerns when primary and
Chm2004 secondary magnitudes or proper motions were the same.)
