Long-Term Spectroscopic Monitoring of B[e] Stars at the Ondřejov Observatory

We present a project devoted to a systematic spectroscopic monitoring of stars showing the B[e] phenomenon. The observations have been performed during the past thirteen years with the Perek 2 m telescope at the Ondřejov Observatory, Czech Republic. Most of the studied objects are of the FS CMa type. We were able to detect expanding layers, rotating structures in the disk, and signatures of material outflow and inflow. Some of the objects show different behavior in different observation epochs. The amount of obtained material is currently sufficient to allow more detailed studies using numerical modeling.
