Abstract

The BN-IRc2 infrared cluster in the Orion giant molecular cloud is the nearest site showing recent massive star formation. Based on its apparent association with energetic phenomena (high velocity molecular flows, compact radio emission, maser emissions), the IRc2 object has been tentatively identified as the infrared signature of a massive YSO, revealed by its SiO maser emission, and providing most of the luminosity radiated by the KL nebula (Wynn-Williams et al., 1984). A circumstellar disk, whose presence is suggested by the near-infrared observations of Chelli et al. (1984), could collimate the flow along its polar axis.
