Scientific paper

A polarimetric map at L-prime (3.8 microns) has been prepared of a 40 arcsec region centered on the infrared cluster in Orion. The percentage of polarization exceeds 30 percent at many positions in the source. This fact, along with the systematic alignment of the polarization position angles, demonstrates that scattering is the principal polarization mechanism prevailing over most of the region. The Becklin-Neugebauer source and IRc2 are identified as the main sources responsible for illuminating the scattering grains. In addition, it is shown that the spatial distribution of dust in the immediate vicinity of IRc2 may be highly anisotropic. The results support the point of view that IRc2 is a highly luminous object, whereas others of the compact infrared sources may simply be isolated, nonluminous fragments of the cloud.
