Fig. 6
Comparison between the normalised and continuum-subtracted spectrum of one of our sample stars ST Pup and the laboratory spectra of ortho-enstatite (dot-dashed line) and clino-enstatite (dashed line) with a 10% iron content, as presented by Chihara et al. (2002). The strong observed feature in ST Pup around 16 μm is due to forsterite.
