Scientific paper

The irregular variable star BS Tauri (type Inbs?) is found to have not only H-α emission and an irregular brightness variation but also an underlying six-year periodicity in brightness. BS Tau should actually be classified as a classical T Tauri star (Int, CTTS), but whether the cyclicity is caused by starspots, a companion, or a circumstellar disk is not certain. Tests to determine the origin of variation are listed.
