摘要：
We conducted a high-sensitivity high-resolution survey in the 230 GHz CO(2-1) line throughout a major fraction of the TMC1 complex (Heiles cloud 2) to search for molecular flows from young stellar objects. Our observations show a, large number of unknown flows from known or unknown objects. The flows have a wide range of morphologies on scale sizes from 0.01 to 1 pc. A first analysis suggests an alignment among flows in parallel to magnetic fields as derived from optical polarization measurements. The area density of flows is sufficiently high to suggest an important impact on the cloud and the star formation within.
