Popis: The circumstellar shells of M stars produce emission features due to amorphous silicates peaking around 10 and 18 μm, with additional emission at 11 μm due to crystalline olivine and at 13.1 μm (unknown carrier). C stars are associated with SiC dust emission at 11.2 μm with additional emission around 8.9 μm, whereas S stars have a relatively weak 10.5 μm emission feature which is due neither to silicates nor to SiC.
