STF2084 zet Her = 40 Her.
Mk III Limb-darkened diameter 2.33 +/- 0.05 mas. MkT2001
Mk III Limb-darkened diameter 2.367 +/- 0.051 mas. MkT2003
NPOI Limb-darkened diameter 2.49 +/- 0.09 mas. NOI2001b
Berman (1941) has discussed the RV's. Ber1941
A subsystem with a period of about 12 yr has repeatedly been
suspected (cf Baize 1976), and the third component has now been Baz1976
detected by infrared speckle interferometry. Mcy1983
No evidence in the speckle or Hipparcos data for the large-amplitude
third-body orbit given by Baize.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Giant primary according to isochrone fit. Sod1999
H 1 36. MEv2010
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 2.44 +/- 1.31, 2.12, and 1.26 Msun, respectively. Mlk2012
