Scientific paper

Spectropolarimetric observations of the BN object at 10 and 20 microns reveal a surprisingly large ratio of 20-to-10-micron polarization in the respective peaks. The results are compared with the predictions of core/mantle grain models based on graphite and ice mixtures with a variety of silicates. Except for a glassy bronzite, in which the wavelength match to the peak in the 20 micron region is very poor, all of these predict substantially smaller amounts of 20-micron polarization than is observed. It seems that either the astronomically important silicates have a particularly strong Si-O bending mode, or that the presence of impurities in ice mantles introduces large 20 micron polarization.
