discov_num notes refcode
MCA 47 Martin et al. (1998) derive component masses 1.150 +/- 0.229 and
2.624 +/- 0.372 Msun. Mig1998
V819 Her 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. Zas2014b
