    Relative lithium abundances in pre-main-sequence spectroscopic binaries
    We present a study of the lithium abundance of five pre-main sequence (PMS) double-lined binaries. These binaries are composed of weak-lined T Tauri stars...

    The lithium resonance line in T Tauri stars
    High-resolution spectra provide evidence of the Li-I 6707 line in 28 of the stars, and the significance of the results is discussed. The Li-I equivalent widths...

    Understanding the Angular Momentum Evolution of T Tauri and Herbig Ae/Be Stars
    We investigate a sample of six Herbig Ae/Be stars belonging to the Orion OB1 association, as well as 73 low-mass objects, members of the σ Orionis cluster, in...

    Weak and post-T Tauri stars around B-type members of the Scorpius-Centaurus OB association
    I report medium-resolution spectroscopic observations of six H emission-line stars proposed by Meyer et al. (1993) to be T Tauri stars formed in the vicinity of...
