... Since I do not work on YSO research these are not a concern for me, but the spectra show a wide variety of features. This particular spectrum shows silicate dust absorption features at 10 and 18 microns, plus narrower absorption bands due to different types of ices (water, CO, CO 2 ). ... Finally at upper right is shown an ISO spectrum of another PPN candidate object, and in this case one sees both crystalline silicate dust and the aromatic/UIR features in the spectrum. ...
