PROBING THE FLARE AND DISK STRUCTURE OF T TAURI STARS
ABSTRACT
We propose long look observations of V773 Tau. V773 Tau is a very active T Tauri star which frequently exhibits large X-ray flares. We investigate (1) a flare duty ratio, (2) heating and cooling processes of the flaring plasma, (3) a structure of a circumstellar disk using the absorption column density during flares, and (4) the low metal abundance problem observed in young stars. The observations will lead to our understanding of X-ray flares from T Tauri stars.
