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