Martin et al. (1998) derive component masses 1.150 +/- 0.229 and |
|
|
2.624 +/- 0.372 Msun. |

Ba,Bb: Period fixed from spectroscopic orbit by Scarfe et al. (1994). |
Scf1994 |
|
The visual secondary is a 2.2d eclipsing binary (V819 Her). |
|
|
Ba,Bb: Mass-sum in agreement with Scarfe et al. (1994). |
Sod1999 |
|
Ba,Bb: Scarfe et al. (1994) give a combined spectroscopic/speckle |
|
|
solution, yielding distance, masses, etc. |
Scf1994 |
|
Ba,Bb: Muterspaugh et al (2008) combine PHASES astrometry with speckle |
|
|
and radial velocity data to derive orbits for both the AB and Ba,Bb |
|
|
pairs of this triple. The parallax is determined at 14.57 +/- 0.19 mas |
|
|
(distance 68.65 +/- 0.87 pc). Masses of the A, Ba, and Bb components |
|
|
are 1.799 +/- 0.098, 1.469 +/- 0.040, and 1.090 +/- 0.030 Msun. |
Mut2008 |
|
Ba,Bb: O'Brien et al. (2011) derive an orbit for the B component via a |
|
|
chi-square fit to interferometric visibility measurements from |
|
|
observations of fringe packets at the CHARA Array. The mutual |
|
|
inclination compared with the AB orbit is 33.5 +/- 9.3deg. Combined |
|
|
with spectroscopy by Scarfe et al. (1994), they derive masses for A, |
Scf1994 |
|
Ba, and Bb of 2.566 +/- 274, 1.488 +/- 0.181, and 1.079 +/- 0.148 Msun, |
|
|
respectively. Parallax is 14.5 +/- 0.2 mas, yielding a separation |
|
|
between Ba and Bb of 0.04573 +/- 0.00163 au. The age of the system is |
|
|
estimated at 1.9 +/- 1.1 Gyr. |
CIA2011c |
|
Zasche et al. (2014) derive a combined solution, including |
|
|
interferometry plus times-of-minimia variations in the Algol-type |
|
|
eclipsing-binary secondary. They determine a distance of 68.8 +/- |
|
|
1.8pc and a mass for the secondary of 1.86 +/- 0.30 Msun. |
