THE PROTOSTELLAR ORIGIN OF A CS OUTFLOW IN S68N

We have discovered a compact outflow of approximate to 80'' (0.12 pc) total extent toward S68N in the Serpens molecular cloud, which we have imaged in CS. We present outflow images acquired with the Haystack 37 m antenna and from combined Haystack and interferometric data, the la tter at 12'' x 6'' angular resolution. The large derived outflow momen tum flux (similar to 2 x 10(-4) M-circle dot km s(-1) yr(-1)) is consi stent with the high values found in the earliest protostellar stage (B ontemps et al.), We also present a new 450 mu m continuum image of the S68N region at 7'' resolution obtained with the Submillimetre Common User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope. We identify the source responsible for this outflow for the first time fr om the SCUBA image and report a new, more accurate position for S68N t han has been used in previous investigations. We demonstrate spatial v ariability in the self-absorbed CS J = 2 --> 1 line profile shapes at 0.03 pc (18'') scales, emphasizing the need for detailed radiative tra nsfer modeling for disentangling the complicated source kinematics.
