WDS 21102+2045 RAO 25 : NOTES
 
 
discov_num notes refcode
RAO 25 Pair has a variable RV (Nordstrom et al. 2004), so the 3".3 companion N rd2004
B discovered by Robo-AO makes it a triple system (estimated period of .
AB is 2000 yr, too long to cause the RV variation). We found the B .
component to be on the [Fe/H] = -0.5 isochrone, in agreement with .
[Fe/H] = -0.54 measured for A (Reddy et al. 2003 MNRAS 340, 304). R br2015d
