Description

High resolution and high signal to noise ratio CCD observations of 59 Cyg show periodic variations in the radial velocities of the components of the Hα line, i.e., of the absorption component, and of the intensity ratio of the blue and red emission components. The period of 29.14 d suggests duplicity of this star. (author). 2 figs., 1 tab., 5 refs
