摘要：

We present the preliminary results of a study of the Ca II IR triplet in a sample of weak-line T Tauri stars (WTTS) in Taurus-Auriga. We find that all the WTTS show the presence of a chromospheric emission component in the absorption lines. Moreover the WTTS take up a peculiar position in the E.W.(CaII) versus log L-X, and in the plot E.W.(CaII) versus E.W.(H alpha) diagrams as compared to that of the held dwarf and to the Pleiades stars.
