Classical T Tauri stars offer a unique window into star+disk systems that are still in the accretion/outflow phase yet are no longer surrounded by an opaque circumstellar envelope. These objects hold the key to understanding how magnetospheric accretion occurs, how accretion powers outflows, and what the physical and chemical conditions are in the disks where planet formation occurs. Far-ultraviolet spectra of classical T Tauri stars provide powerful and unique diagnostics of each of these processes. In the ongoing Disks, Accretion, and Outflows of T Tau stars (DAO of Tau) program, we are using HST/COS and STIS to survey these diagnostics in high-resolution FUV spectra of 26 CTTSs and 6 WTTSs. Our first results include identifying new emission line diagnostics of the disk surface, detecting weak accretion in profiles of hot lines from a WTTS with a disk, finding warm winds from only some objects, and catching an amazing flare on a WTTS.
