very high (near 100%) probability pair is physical. | ||
WSI 7 | Aa,Ab: Tokovinin et al. (2014) derive a combined spectroscopic/ | |
interferometric orbit of the Aa,Ab pair, as well as a new orbit of the | ||
AB pair. Resulting component masses for Aa, Ab, B, and C are 0.74, | ||
0.72, 0.57, and 0.78 Msun, respectively. | Tok2014b |
