The emission lines of Be stars are usually double peaked due to the rotation of the circumstellar disk. Zeta Tauri exhibits this feature in both the Hα and Fe II lines, with the V/R ratio of the peaks varying periodically due to different density regions in the disk. At certain times the Hα emission becomes triple peaked, a phenomenon yet to be completely explained. A spiral shaped disk has been proposed as a model that can explain the triple peak in the Hα emission. To attain a better picture of the disk structure, we investigate the behavior of the Hα, Fe II, and He I lines of Zeta Tau. The observations span from 1997 to 2006, and were taken at the Ritter Observatory at the University of Toledo.
This research was supported by the REU program at the University of Toledo, with funding provided by the NSF.
