Physics

Scientific paper

The nearby T Tauri star, TW Hya exhibits far ultraviolet and infrared emission lines with a P Cygni shape that signal the presence of a continuous, fast (400 km/s), hot (300,000 K) accelerating outflow with a mass loss rate 10-11 - 10-12 solar masses per year or larger (Dupree, Brickhouse, Smith, Strader, 2005, ApJ Letters in press). Because TW Hya has a low inclination, and the surrounding accretion disk is face-on, the stellar polar regions are observed directly. We consider the emission measure distribution of the star, the sources of the emission and implications for the origin of the X-rays.
