Molecular CO Outflows in the L1641-N Cluster: Kneading a Cloud Core

We present results of 1.3mm interferometric and single-dish observations ofthe center of the L1641-N cluster in Orion. Single-dish wide-field continuumand CO(2-1) observations reveal the presence of several molecular outflowsdriven by deeply embedded protostellar sources. At higher angular resolution,the dominant millimeter source in the cluster center is resolved into a pair ofprotostars (L1641-N-MM1 and MM3), each driving a collimated outflow, and a moreextended, clumpy core. Low-velocity CO line-wing emission is widely spread overmuch of the cluster area. We detect and map the distribution of several othermolecular transitions (13CO, C18O, 13CS, SO, CH3OH, CH3CN, and OCS). CH3CN andOCS may indicate the presence of a hot corino around L1641-N-MM1. Wetentatively identify a velocity gradient over L1641-N-MM1 in CH3CN and OCS,oriented roughly perpendicular to the outflow direction, perhaps indicative ofa circumstellar disk. An analysis of the energy and momentum load of the COoutflows, along with the notion that apparently a large volume fraction isaffected by the multiple outflow activity, suggests that outflows from apopulation of low-mass stars might have a significant impact on clustered (andpotentially high-mass) star formation.
