- Abstract
We have analyzed a many-year homogeneous series of spectroscopic data for the star T Tau N. Our optical observations of hydrogen lines and the Hand K lines of CaII have revealed periodic variations of the emission spectrum with a period of 33 ± 1.5 days. The detected period is also observed in IUE spectrograms in the ultraviolet. Variations of the polarization of the star's light also agree with the derived period. Our results suggest the possible presence of a comet-like extended object orbiting T Tau N.
