discov_num notes refcode
CHR 193 is also a spectroscopic binary with a P of 447d. Tok2019b
HU 644 Beuzit et al. (2004) AO observations confirm speckle third component Beu2004
of Hartkopf et al. (1994). Mass sum and mass ratio (Heintz, 1969) Hrt1994
clearly requires the primary to be a closer binary. Hei1969c
Masses and bolometric magnitudes are derived for the two components Msn1999a
of this system by Mason et al. (1999), based on assumed spectral types
and available parallaxes. The Hipparcos parallax appears suspect.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
HU 644 AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 1.76 +/- 0.13, 1.11, and 0.85 Msun, respectively. Mlk2012
Aa,Ab: 1992.3126: This appears to be a new component to the 1".5 49-yr
period pair of K/M dwarfs HU 644. This is the only one of the current
crop of new interferometric binaries which has not yet been confirmed.
