Scientific paper

We present our initial observations of the Be star ζ Tau obtained using the Michigan Infrared Combiner at the CHARA Array. We computed simple geometric models that account for the asymmetry we detect in the disk. Our long term goal is to continue a multi-year monitoring campaign to follow the outward motions of disk enhancements. This work will be complemented by spectroscopy of the emission lines to investigate the development of asymmetric structures, such as spiral arms, in the disk.
