,From Dust Astrophysics Towards Dust Mineralogy – A Historical Review,cted at 217 nm in the interstellar extinction curves was commonly assigned to graphite grains. Beginning in 1968, observations of the vibrational bands of the SiO. group in circumstellar as well as in interstellar dust provided ample evidence for the ubiquitous occurrence of silicate grains in the G

The Mineralogy of Cometary Dust,arts of the solar nebula where temperatures remained low enough so that interstellar grains could have survived. The small glassy silicates in comets may indeed be interstellar grains. The CAI and the widespread, abundant crystalline silicates must have condensed in the hot inner solar nebula; their

The In-Situ Study of Solid Particles in the Solar System,directly measured yet, their conditions of entry into the solar system reveal the forces that are acting on them. The forces depend on the properties of dust and allow for a comparison to astrophysical models of dust size, composition and structure. In-situ measurements with improved dust detectors

The Most Primitive Material in Meteorites,to ~200 ppm..Isotope abundance anomalies are the key feature based on which the presolar nature of a given grain is ascertained. 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
