Abstract

We present the results of time variability analysis of the Hα, He I (λ5876 Å) and Na D (λ5890, 5896 Å) lines in two active T Tauri stars, DL Tau and DR Tau. The aim is the study of time behavior of these lines, during one week, as well as possible correlations among them. The observed profiles of some lines are very complex, often showing characteristics of outflow and accretion.
