Scientific paper

This report describes a study of the ultraviolet spectrum of the B-shell star, zeta Tauri. The observational material consists of high-dispersion spectrograms obtained from a rocket experiment launched in November 1972. The spectra cover the wavelength interval from 1100 to 2050 A with a resolution of about 0.1 A. The UV stellar lines indicate that the star has an effective temperature as high as 27,000 K, the stellar atmosphere appears to have serious abundance deficiencies in carbon and silicon, and the velocity field in the atmosphere is complicated but shows evidence for outward acceleration and differential rotation.
