Abstract:
Zeta Capricorni (ζ Cap HD 204075) was shown to be a Barium line spectroscopic binary, possessing strong BaII line by Bohm-Vitense (1980), Smith et al.(1980), Culiver (1981) and Smith and Lambert (1984). ζ Cap is shown to have a white dwarf companion by Bohm-Vitense (1980), which is much fainter than ζ Cap. Photoelectric observations of ζ Cap. Photoelectric observations of ζ Cap are hardly available in the literature except for the color indices (B-V=1.ͫ00 and U-B=0.ͫ59, Sp.=G5) given by Eggen (1972).
