discov_num notes refcode
MCY 1 Aa,Ab: Discovery designation is per Todd Henry 03/02/98.
K-band magnitudes of components 6.42 and 8.44, derived masses are
0.377 +/= 0.030 and 0.138 +/- 0.007 Msun. Doc2008d
VYS 2 AB: ADS 433, MLB 377. The primary is an astrometric binary, P=16y.
Proper motion +1.723 -0.242. A premature orbit has been computed for
the visible pair.
Also a flare star, V547 Cas.
Woitas et al. (2003) give orbital solution and determination of Woi2003
dynamical masses for this low-mass M dwarf triple.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Solution includes mass determination. Woi2003
In the orbit catalog figure illustrating the Docobo et al. (2006) Doc2006g
orbital solution, B is plotted relative to the center of mass. These
adjusted measures were provided by Docobo (2007, private comm.) See
also further analysis by Docobo et al. (2008), who derive a mass for Doc2008d
the B component (K-band mag 7.88) of 0.177 +/- 0.014 Msun (see note to
MCY 1 pair above for masses of Aa and Ab components.)
GL 22 Ba,Bb: Andrade & Docobo detect a sinusoidal pattern in the motion of
the B component, which they attribute to a possible 4th component of
the system in a 15y orbit. Masses under this scenerio are 0.162 +/-
0.014 Msun for Ba and 0.0152 +/- 0.0053 Msun (16.0 +/- 5.6 Mjup) for
Bb (assuming a circular solution) or 0.0147 +/- 0.0027 Msun (15.4 +/- Ana2009
2.8 Mjup) for Bb (assuming an elliptical solution). The Bb component
may be either a giant planet or a brown dwarf. Ana2011
