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. |
