Bidelman, William “Billy” Pendry
摘要
William (“Billy”) Pendry Bidelman was one of the last masters of photographic stellar spectral classification and the identification of peculiar stars. His discoveries included barium stars, hydrogen-deficient stars, high-galactic-latitude supergiants, stars with anomalous carbon content, and exotic chemical abundances in peculiar A and B stars. Bidelman was legendary for his encyclopedic knowledge of the stellar literature. Some of the bizarre stellar phenomena he discovered remain unexplained to the present day.
