Discovery of Large 10-MICRON Linear Polarization of the Becklinneugebauer Source in the Orion Nebula
Abstract
The Becklin-Neugebauer source in Orion has been found to be highly polarized in the 5-Il spectral range. From 8 to 11 , the polarization is strongly correlated with the optical depth in the l0- absorption feature and reaches a maximum value of about 15 percent at 10 . The observations are consistent with the polarization being produced by a cloud of cool, absorbing, elongated, aligned dust particles around or in front of BN.
