OUTFLOWS FROM YOUNG STELLAR OBJECTS IN BOK GLOBULES - MAPS

We have obtained (CO)-C-12 J = 1-0 spectral line maps of high-velocity gas outflows from a sample of 14 small Bok globules containing low-ma ss young stellar objects (YSOs). The observations were performed using the new 15 beam receiver (QUARRY) of the Five College Radio Astronomy Observatory. Morphologically, the outflows in our sample exhibit smal l angular extents, and relatively wide angular lobes with the majority exhibiting low apparent degrees of collimation. The presence of an ou tflow was found to be correlated with the value of the IRAS-based spec tral index (between 12 and 25 mum) of the YSOs. Outflows were more fre quently detected in those globules with the reddest IRAS point sources . These spectral indices are consistent with emission from objects in fairly early stages of the star formation process which are still deep ly embedded in ps and dust. Energetically, the outflows in our sample may be among the weakest and least massive found to date. Nevertheless , both the outflow kinematics and energetics indicate that they may pl ay an important role in cloud support and evolution.
