Molecular outflows associated with young stellar objects in the L1641 region of Orion

The results of a follow-up survey of a flux-limited sample of IRAS sources located in the L1641 region south of the Orion Nebula are presented. The molecular outflow sources identified include all previously known molecular outflows and, reported for the first time, three additional molecular outflows. None of the observed molecular outflows appear to be oriented along a preferred direction, and they are also distributed nonuniformly throughout the L1641 region. Maps of the molecular outflows suggest that the direction of the molecular outflow may be shaped by the ambient molecular cloud. The estimated momentum of the observed molecular outflows is found to be sufficient to support the molecular cloud over the dissipation time scale against gravitational collapse.
