They also allow identifying likely stellar sources for the grains. The major source of SiC, the oxide and the silicate grains are Red Giant/AGB stars, while some (~1%) of

The Mineralogy of Interstellar and Circumstellar Dust in Galaxies,environment in which it is found. Dust can therefore be used as a tracer and probe of the physical and chemical conditions where it is detected. We present an observational overview of interstellar and circumstellar dust using spectroscopy at infrared wavelengths. Thanks to the contributions made by

The Mineralogy of Cometary Dust, other minerals. While forsterite Mg.SiO. and enstatite MgSiO. are the most common silicate minerals, both the olivine and pyroxenes also show a wide range in Mg/Fe in at least some comets. Carbon in the dust is enriched relative to CI chondrites; a significant fraction of the carbon is in the form

The Astromineralogy of Interplanetary Dust Particles,beyond the giant planets, presolar grains or “astrominerals” with solar and non-solar isotopic compositions are expected to be even more abundant in cometary IDPs than in primitive meteorites. Non-solar D/H and .N/.N isotopic enrichments in chondritic IDPs are associated with a carbonaceous carrier.

Diamond was the first and may occur with an abundance ￣1‰, but it is not clear what fraction of the observed nanometer-sized diamonds is truly presolar. Others found by this approac
