AN EXTREMELY HIGH-VELOCITY MULTIPOLAR OUTFLOW AROUND IRAS-20050+2720

We report high angular resolution maps in the CO 2 --> 1 and CS 3 --> 2 lines of the molecular gas around the embedded object IRAS 20050+202 7. This is a 260 L. source located in the Cygnus Rift at 700 pc from t he Sun. The CS data uncover a dense core of size 0.3 pc and 80 M. cent ered on the IRAS object. The CO map reveals a remarkable molecular out flow consisting of three pairs of lobes emanating from the close vicin ity of the IRAS source. One of the lobe pairs is a highly collimated j et of extremely high velocity emission (LSR velocities up to +70 km s( -1)) containing molecular ''bullets.'' We briefly examine different po ssibilities to explain the complex structure of the multipolar outflow . A single outflow appears unable to explain all the CO observations, so we suggest that two or three independent outflows emanate from diff erent young sources embedded within the core.
