KSA 1 | Kraus et al. (2007) derive spectral types M5, M5.2, and M5 (all +/- | KsA2007b |
0.5) for the Aa, Ab, and B components, respectively. Masses are 0.14, | ||
0.12, and 0.14 (all +/- 0.02) Msun. Projected separation of Aa,Ab is | ||
7.7 +/- 1.2 au, that of AB 1600 +/- 200 au. Conclude that Aa,Ab is a | ||
close binary with B a young, comoving member of the Upper Scorpius | ||
association. |
