BU 646 113 Her. The G-type component is a long-period spectroscopic binary.
MKT 9 Visual orbit by Hummel et al. (1995) based on astrometry from Mark III MkT1995
interferometer. Additional spectroscopic data yield component masses,
luminosities, radii, effective temperatures, and distance.
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Hummel et al. (1995). MkT1995
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 1.71 +/- 3.27, 5.64, and 4.08 Msun, respectively. Mlk2012
Aa,Ab: Ren & Fu (2013) calculated an astrometric orbit, combining Ren2013
Hipparcos Intermediate Astrometric Data with spectroscopic elements by
Luyten (1936). Luy1936
