One component is a spectroscopic binary. |
|
|
Aa,Ab: Docobo & Andrade (2013) derive a dynamical parallax of 3.88 +/- |
|
|
0.56 mas and component masses 6.08 +/- 3.43 and 5.45 +/- 3.08 Msun |
|
|
(for spectral type B1.5V) or 3.85 +/- 0.58 mas, 6.27 +/- 3.63 and 5.53 |
|
|
+/- 3.20 Msun (for B2IV). See paper for extensive notes on system. |
