Scientific paper

We present a spectral line image of the region around HLTau which covers a field of about three arc minutes and has an angular resolution of about seven arc seconds. It is based on the combination of a multiple pointing observation in the compact array of the BIMA millimeter array combined with an On-The-Fly single antenna observation with the NRAO 12m antenna. The overall structure in the map is dominated by an expanding bubble of gas approximately centered on XZTau and a smaller bubble centered on LHα358. Evidently winds from these stars have a major effect on the large scale structure. The expanding bubbles show the way in which gas is cleared out in this region. The velocity structure near HLTau appears to be totally dominated by the motion of the bubbles.
