Aa,Ab: bet Cep = 8 Cep = Alfirk. The third component was discovered |
|
|
recently by speckle interferometry. |
|
|
1971.48: Estimated delta m ~ 3 - 4. Attempts by Couteau (1973 private |
|
|
communication) to observe the companion visually were unsuccessful, |
|
|
supporting this large magnitude difference. Some anisotropic features |
|
|
in the Fourier transform may indicate other companions or |
|
|
circumstellar matter. |
Lab1974 |
|
1975.545, 1975.956: This is the primary of the system bet Cep and is |
|
|
believed to be a binary of period ~50 yr. There is also evidence of |
|
|
radial velocity variations. Labeyrie et al (1974) noted anisotropic |
Lab1974 |
|
features in the power spectrum which might indicate other companions, |
|
|
but such features were not observed in the power spectrum derived from |
|
|
these observations. |

Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and |
|
|
spectroscopic masses 9.98 +/- 3.28, 12.04, 12.02 Msun, respectively. |

Uniform disk diameter 0.274 +/- 0.016 mas, |
|
|
Limb darkened diameter 0.280 +/- 0.016 mas, |
|
|
Teff = 29500 +/- 2500 K based on LDD. |
|
|
Radius is 7.22 +/- 0.42 \rsun. |
