Abstract:
    An objective prism survey for H{alpha}-emission-line stars towards the HII
    regions RCW 27, 32 and 33 and the northwestern parts of the Vela Molecular
    Ridge is presented. 278 H{alpha}-emitting objects have been found and their
    relation to the HII regions and to dark clouds in the area is discussed. We
    identify what appears to be two new large associations of T Tauri stars,
    Vela T1 and T2, at a distance of 1 kpc. The relation of low-mass
    H{alpha}-emission stars with the Vela Molecular Ridge is discussed.
