discov_num notes refcode
STFB 7 93 Leo = LDS4146. A is a spectroscopic binary and light variable,
spectrum composite; A7V+G5III-IVe. B is BD+21@2357.
AB: HJL 156. HJL1986
AB: H 6 80. MEv2010
MKT 7 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.
Pourbaix gives combined solution for this resolved SB2, yielding Pbx2000b
orbital parallaxes and component masses.
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 3.97 +/- 0.25, 4.97, and 1.66 Msun, respectively. Mlk2012
