Scientific paper

We have begun an objective-prism H-alpha survey of star-forming regions using the Centro de Investigaciones de Astronomia 1 m Schmidt Camera, with a limiting magnitude V of about 18. We report here first results for selected areas of the Taurus-Auriga molecular clouds. Of the list of candidates found in the objective-prism plates, twelve stars have been confirmed as pre-main sequence by the detection of the Li I 6707 A absorption line. Five of these stars are in the dark cloud L1544, where only one T Tauri star was previously known. The new stars have very late spectral types and most have estimated masses between 0.2 and 0.3 solar mass.
