A: del Cep = 27 Cep. Prototype of the Cepheid variables, P = 5.36d. |
|
|
A: Gallene et al. (2016) searched for close companions to del Cep, |
|
|
using the CHARA Array. H-band magnitude limits for separation regimes |
|
|
r < 25 mas, 25 < r < 50 mas, and 50 < r < 100 mas of 6.17, 5.63, and |
|
|
5.26 mags correspond to spectral type limits for possible companions |
|
|
of F0V, A1V, and B9V, respectively, |

STTA235. C is variable and a spectroscopic binary. |

C: Benedict et al. (2002) used the HST FGS3 to derive parallaxes for |
|
|
del Cep (3.66 +/- 0.15 mas) and its 40" companion HD 213307 = STFA 58C |
|
|
(3.65 +/- 0.15 mas). Residuals to the data for the C component showed |
|
|
long-term and non-linear trends, which they used to derive a |
|
|
preliminary perturbation orbit with period 390d and a = 2.0 mas. |

|
In addition to detecting the unresolved spectroscopic companion with |
|
|
P = 2202 +/- 6d a parallax of 4.09 +/- 0.16 is determined for the |
|
|
system from Hipparcos Intermediate Data. |

Masses are 5.2 and 4. Msun. Estimated period = 345,000y, |
