BAG 8 | Combined astrometric/spectroscopic solution by Balega et al. (2002), | Bag2002b |
including determination of component masses. | ||
The Balega (2002) orbit predicts a separation of 0.055" in mid-2006, | Bag2002b | |
opening rapidly to 0".197 in late 2007. Perhaps T0 is not quite | ||
correct? | Hrt2009 | |
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic | ||
masses of 1.54 +/- 0.13, 1.54, and 0.79 Msun, respectively. | Mlk2012 | |
A(B) Teff = 5350+/-50(4400+/-50) K, R = 0.95+/-0.06(0.58+/-0.06) \rsun, | AlW2014c | |
L = 0.56+/-0.01(0.10+/-0.02) \lsun, M = 0.83+/-0.05(0.60+/-0.05) \msun. |
