Abstract

A large number of solid dust components have been identified through analysis of stardust recovered from meteorites, and analysis of IR observations of circumstellar shells and the interstellar medium. These include graphite, hydrogenated amorphous carbon, diamond, PAHs, silicon-, iron-, and titaninium-carbide, silicon nitride, magnesium sulfide, aluminum oxide, and various silicates ranging from iron-rich amorphous to magnesium-rich, highly crystalline fosterite (Mg(2)SiO(4)) and enstatite (MgSiO(3)). This diversity of materials reflects the diversity of birthsites and the complex formation and processing history of circumstellar and interstellar dust.
