The study was done with data on Rigel that was taken over the course of 10 seasons, with 192 total observations. All observations were taken with the 1.06 meter telescope at the University of Toledo's Ritter Astrophysical Research Center. I looked for a periodic variation in the hal~ line by looking at the equivalent widths and radial velocities, as well as classifying the profiles into seven categories and determining the frequency of occurrence of each. I also measured the radial velocities of a singly ionized carbon line. A high velocity absorption event, such as the 2 seen by Kaufer et. al. in 1993 and 1994, was also seen in 2006 in this study. No single, dominant periodic component was found in the radial velocity measurements of either line. 2009-09-23 English text University of Toledo / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=toledo1249043423 http://rave.ohiolink.edu/etdc/view?acc_num=toledo1249043423 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
