Scientific paper

Using a sample of 135 Be stars, we present an analysis of spectra taken at the Kitt Peak National Observatory 0.9m Coude Feed telescope in 2004, 2005 and 2006. First we show examples of disk variability over the course of our observations through changes in emission line strength and shape. Second, we describe our analysis of radial velocity variations for evidence of binarity.
