Title: H₂ fluorescence in FUSE spectra of T Tauri
Abstract: We present a deep FUSE FUV spectrum of T Tauri, obtained with FUSE during orbital night, which shows minimal solar scattered light and airglow. We detect both high excitation lines of C III and O VI, and fluorescence H₂ emission. The strongest lines of H₂ are fluorescence by H Ly$\alpha$. We describe our modeling techniques, similar to those presented by Harper et al. (2001, ApJ, 551, 486) and present simulated H₂ and Fe II fluorescent spectra contrained by Archival UV spectra.
