BU 231 omi Cas = 22 Cas
Primary is a spectroscopic binary, P = 1033:d.
NOI 3 Aa,Ab: Hipparcos astrometric solution adopted some elements from the HIP1997d
orbit of Abt & Levy (1978). AbH1978
Koubsky et al. (2010) combined solution uses NPOI astrometric data NOI2010
together with radial velocities from the Dominion Astrophysical and
Ondrejov Observatories. The secondary appears to be of similar mass to
the primary, although the magnitude difference is nearly 3 magnitudes.
One possible explanation might be that the secondary is comprised of a
close pair of similar stars, possible early A dwarfs.
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 6.12 +/- 2.94, 7.39, and 5.62 Msun, respectively. Mlk2012
