BU 513 48 Cas. A is a spectroscopic binary, same period as the visual pair.
Suspected sub-periods of 39 yr (Baize) and 26 yr (Muller) are not Baz1941b
confirmed by later measures. The radial velocities of the primary may Mlr1949c
show a trace of a period of about 4 yr (Heintz). Hei1981e
See Baize & Petit catalog of doubles with variable component. Baz1989d
Masses and bolometric magnitudes are derived for the two components
based on assumed spectral types and available parallaxes.
1980.7205: This measure was incorrectly attributed to ADS 1958 in
McAlister et al. (1983). McA1983
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 2.96 +/- 0.42, 3.07, and 2.00 Msun, respectively. Mlk2012
