Abstract
We have modelled the IRAS observations of the circumstellar dustshells around late-type stars previously studied by Rowan-Robinson and Harris (1982, 1983a, b), using only high quality IRAS fluxes which do not appear extended in the raw data. Figure 1a, b shows the IRAS 12-26-60 colour colour diagrams for late M and carbon stars, together with the predictions of simple model sequences. Figure 2a, b show the spectra of a sample of the stars.
