Speckle observations needed to refine relative orbit. |
|
|
AB: Hipparcos parallax 30.64 +/- 0.70 mas. Dynamical parallax 27.2 mas, |
|
|
masses 1.63 and 1.37 Msun. FIN 363 has an unusually short period of |
|
|
only 3.44 yr. The Hipparcos photometry is doubtful because of close |
|
|
0.1" separation. |
Tok2012b |
|
AB: Martin et al. (1998) derive component masses 3.661 +/- 0.338 and |
|
|
3.661 +/- 0.338 Msun. |
Mig1998 |
|
AB: Docobo & Andrade (2013) derive a dynamical parallax of 29.71 +/- |
|
|
1.33 mas and component masses 1.43 +/- 0.25 and 1.06 +/- 0.20 Msun. |
