Scientific paper

We present 5-40 micron spectroscopy obtained with the Infrared Spectrograph on board Spitzer of a sample of oxygen-rich Asymptotic Giant Branch stars. The spectra of these dust-enshrouded objects all show the characteristic resonances at 9.7 and 18 micron due to 'amorphous' silicates. In addition, several of the spectra show the finer substructure that is ascribed to crystalline silicates, in particular crystalline forsterite. We will explore the range in physical conditions at which these crystalline silicates are found, and compare those to the crystalline fraction seen in Galactic post-main sequence stars in the same evolutionary stage.
