MCA 69 xi Cep = 17 Cep = Kurhah
Aa,Ab is an astrometric binary and SB2, with elements by Vickers & Scf1976
Combined solution by Farrington et al. (2014) yields masses 1.045 +/-
0.032 and 0.409 +/- 0.066 Msun, as well as an orbital parallax 38.11
+/- 2.82 mas. CIA2014a
STF2863 Scarfe (1976). The McAlister (1980) orbit is from speckle McA1980a
xi Cep interferometry, and in good agreement with the spectroscopic result.
Mt. Wilson spectrum of B F8s. Spectrum of A: A3m.
Pourbaix gives combined solution for this resolved SB2, yielding Pbx2000b
orbital parallaxes and component masses.
STF2863 AB: H 2 16. MEv2010
