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 | |
Aa,Ab : 0.7400 +/- 0.0122, 0.1728 +/- 0.0035 \msun, respectively. | BdH2020 | |
Age estimated as 12.7 +/- 2.7 Gyr. | ||
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 | |
