Scientific paper

Observations of carbon monoxide (CO) toward 26 T Tauri stars and related objects are reported. In 19 of these objects, broad CO line wings of intensity greater than about 0.1 K were detected, implying that mass outflow is a common phenomenon in T Tauri stars. The velocity width (full width) of the wings ranges from about 10 to 80 km/sec, and clusters around 25 km/sec. In general, the line wings are asymmetric with respect to the line core and the sense of asymmetry varies among sources. In the case of T Tauri, which has the broadest wings detected in these sources, the sense of wing asymmetry varies with position and may be due to source geometry.
