TRN 2 | Aa,Ab: Astrometric orbit, P=65yr, e=0.32 (Heintz 1994) implies | Hei1994a |
a=0.265", does not fit the 1.4" companion of Turner (2001). | Trn2001 | |
Roberts et al. derive a spectral type for the secondary of M4V +/- 1. | ||
Using an estimated mass for the primary, they estimate the mass of the | ||
secondary as 0.32 Msun. | Rbr2016a | |
Inclination of this orbit appears to be the same as that of the | XXX2017a | |
rotation axis of the primary. | ||

R = 1.64 +/- 0.01 \rsun, Teff = 5425 +/- 69 K, L = 2.1 +/- 0.1 \lsun, | ||
M = 1.09 +/- 0.01 \msun, Age = 7.68 +/- 0.13 Gyr. | ||
STF2220 | A: mu Her = 86 Her is a large-amplitude astrometric binary, P = 65y. | |

AC 7 | BC: Prieur et al. (2014) derive a dynamical parallax of 123.0 mas and | |
a total mass of 0.82 +/- 0.07 Msun (based on the revised Hipparcos | VlF2007 | |
parallax of van Leeuwen 2007). | Pru2014 |
