Scientific paper

The NGC 2071 (North) molecular cloud is investigated in the 3-mm wavelength transitions of CO, (C-13)O, (C-18)O, CS, and HCO(+). The distribution of the tracers CS and (C-18) are found to be very different, both differing appreciably from the previously published distribution of NH3. The (C-18)O, CS, and NH3 are all highly clumped. The standard value for the fractional abundance of (C-18)O is used to determine that the prominent clumps observed in this species are unbound. It is argued that the explanation of the structure and chemical differentiation in this region lies in the presence of an outflow which is found to be centered on the 26-40-solar-luminosity source IRAS 05451 + 0037. The single significant peak of the CS emission coincides with the IR source; one of the four ammonia peaks occurs there, while none of the other tracers has a significant maximum at this position. It is suggested that the molecular abundances in this relatively large region were significantly affected by the outflow and presence of the young stellar object.
