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
