Submillimeter polarization in the Orion Nebula

The author has observed linear polarization of the submillimeter (270 μm) continuum radiation from three regions in Orion: one centered on the Kleinmann-Low (KL) nebula, one centered on the 400 μm peak 1arcmin.5 south of the nebula, and one centered on OMC-2. The polarization measured at KL is P = (1.67±0.24)% at φ = 24±6°, and at the 400 μm peak is P = (1.65±0.32)% at φ = 28±7°. At OMC-2 a 2 σ upper limit is P < 0.7%.
