Observational studies of the symbiotic stars. I. H alf profile variations in CH Cyg.
Abstract
Moderately high resolution H-alpha profiles of the symbiotic star CH Cygni obtained with the Washburn Observatory echelle spectrograph and Reticon detector system over the course of 13 months are presented. Several episodes of profile variability were observed. Various kinematic models for these variations are presented and compared.
