T Tauri Stars: The X-ray Connection

V.M. Costa, M. T. V. T. Lago

Abstract
The launch of ROSAT opened a new era in the study of T Tauri stars. Prompted by the IUE results, the new X-ray data confirms the existence of extremely high levels of activity in these young stars, very likely of magnetic nature. We address a detailed analysis of the star TW Hya in the X-ray spectral range. A summary of its properties in the UV will also be included in order to grasp an overall picture of the activity in this star.
