Spectroscopic investigations of the massive close binary star XZ Cephei.
Abstract
Radial velocities of both components of XZ Cephei were measured from 18 spectrograms with inverse dispersion 28 and 9 A/mm. A radial-velocity curve was computed separately for He, I, H, and light-element lines. Spectroscopic orbital elements of the system were also obtained.
