Ba,Bb: Hipparcos parallax 25.39 +/- 0.43 mas; dynamical parallax 25.5 |
|
|
mas, masses 1.08 and 0.80 Msun. The new orbit with 14 yr period is |
|
|
radically different from the 28.5 yr orbit of Cvetkovic (2008), but |
Cve2008b |
|
closer to the three solutions proposed by Branham (2009). A large part |
Bnh2009 |
|
of the orbit remains unobserved. |
