The Far-Ultraviolet Spectrum of T Tauri between 912 and 1185 Å

We report on a Far Ultraviolet Spectroscopic Explorer (FUSE) spectroscopic observation of the pre–main-sequence star T Tauri, the defining object of pre–main-sequence stars. The FUSE satellite is the only UV instrument currently available that can acquire high-quality spectra between 912 and 1185 A. The spectrum of T Tau was acquired between 2000 January 15 and 16. Serendipitous observing conditions resulted in a very low noise spectrum that allowed the detection of several weak features, including the first detection of H2 Werner-band emission in an extrasolar object.
