Details

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. BD Camelopardalis is an S star and symbiotic star in the constellation Camelopardalis. It was recognized as a spectroscopic binary star in 1922, and its orbital solution published in 1984; it has a 596-day orbital period. A spectroscopic composition analysis was done of the red giant primary star in 1986. Although its spectrum shows the spectral features of zirconium oxide which define spectral class S, it shows no technetium lines in its spectrum. It is believed to be an "extrinsic" S star, one whose s-process element excesses originate in a binary companion star. The system displays only minimal variations in the visible, the presence of the companion and its interactions with the stellar wind of the visible red giant makes for easily observed time-variable spectral features in the ultraviolet and in the near infrared spectral line of helium.
