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 |
