discov_num notes refcode
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.
Mk III Limb-darkened diameter 1.953 +/- 0.039 mas. MkT2003
NPOI Limb-darkened diameter 1.880 +/- 0.008 mas, Sp = G5IV, NOI2018
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.
A,BC: LDS1002. HJL 253. HJL1986
A,BC: H 4 41. MEv2010
A,BC: Additional notes may be found in Baize (1964). Baz1964
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
