Scientific paper

The low velocity H2O maser features and the hot core component identified in the spectra of the NH3 inversion lines from the center of the KL cluster in Orion may represent a low velocity outflow from IRc2. The origin of the high velocity flow is at present, however, uncertain. The low and high velocity flows may actually be close to each other at the center of the cluster. The masses contained within the two flows, or the implied mass loss rates, are high and similar for the two flows. Such large mass loss rates exclude the Becklin-Neugebauer object as a source of an important fraction of the high velocity flow, since the current mass loss at the surface of the star is 2-3 orders of magnitude too low.
