We have begun an objective-prism Halpha survey of star-forming regions
using the CIDA 1 m Schmidt Camera, with a limiting magnitude V almost
-equal-to 18. We report here first results for selected areas of the T
aurus-Auriga molecular clouds. Of the list of candidates found in the
objective-prism plates, twelve stars have been confirmed as pre-main s
equence by the detection of the Li I 6707 angstrom absorption line. Fi
ve 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 M. and 0.3 M..
