Abstract
Mid-infrared spectroscopic and spectropolarimetric observations of three star formation regions are presented, from which the dust mineralogy is inferred from modelling of the spectra. Crystalline olivine is shown to be a good candidate for the carrier of the 11.2 µm feature observed toward AFGL 2591, whilst metal oxides are proposed as a possible component of the dust toward the BN Object in Orion. SiC appears to be present in the circumstellar disk of SVS13 (HH7-11 IR).
