A: HBC 644 = Haro 1-14c PMS binary resolved by Keck Interferometer. |
|
|
The orbit is based on V^2 measurements obtained 2004-2007, plus radial |
|
|
velocity data from 2001-2007. The best-fit masses and distance from |
|
|
statistical analysis of the orbital solutions are 0.961 +0.265/-0.083 |
|
|
and 0.326 +0.092/-0.023 Msun; 111 +19/-18 pc. A comparison with |
|
|
evolutionary tracks suggests an age of 3-4 Myr. |
Sfr2008 |
|
A combined solution yielded masses 0.905 +/- 0.043 and 0.308 +/- 0.011 |
|
|
Msun, plus a distance of 95.55 +/- 9 pc. |
