WCK 1 Aa,Ab: mu Cas = 30 Cas. Proper motion of A +3424 -1596 (FK5).
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 0.01 +/- 0.01, 1.22, and 0.95 Msun, respectively. Mlk2012
mu Cas Aa,Ab: Astrometric orbit. Spectroscopic elements are somewhat
different from those of Lippincott: P = 23.0, T = 1954.0, e = 0.30, Lip1981
omega = 178.0 (Worek & Beardsley 1977). Bey1977
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
The pair has now been resolved by infrared speckle interferometry. Mcy1983
Pierce & Lavery (1985), Karovska et al. (1986), Haywood et al. (1992), Pie1985
and McCarthy et al. (1993) all compare their observations with Kar1986b
published orbits and discuss luminosities and masses of components, Hay1992
helium abundances, etc.
Hipparcos astrometric solution adopts some elements from the orbit HIP1997d
of Heintz & Cantor (1994). Hei1994b
CHARA Array Limb-darkened diameter 0.973 +/- 0.009 mas, CIA2008d
R = 0.791 +/- 0.008 \rsun, Teff = 5297 +/- 32,
L = 0.442 +/- 0.014 \lsun.
CHARA Array Limb-darkened diameter 0.972 +/- 0.009 mas, CIA2012e
R = 0.790 +/- 0.009 \rsun, L = 0.428 +/-0.007 \lsun,
Teff = 5264 +/- 32 K.
STT 551 AB: Optical pair, based on study of relative motion of the
components using the method of apparent motion parameters. Kiy2008
