The dark cloud L1251 has been studied by mapping the J = 1-0 transition of (C-12)O, (C-13)O, and (C-18)O to elucidate the star formation within the cloud. Two molecular outflows, probably caused by two IRAS point sources with low luminosities, are found in an active star formation region. The colder source, during a compact outflow, lies in the midst of a dense core. The warmer source, driving an extended outflow with a dynamical time scale of about 110,000 yr, is situated outside the dense core, suggesting that it is older than the colder source. The extended outflow is interacting with the dense clump in the cloud. Once a protostar forms a dense core, its outflow probably disrupts its placental cloud core, reducing its ambient density. 18 refs.
