Outline of Final Research Achievements

In this research, by analyzing space mission data from Cassini, Stardust, and Rosetta for interstellar dust and cometary dust as well as astronomical observation data of interstellar gas by Hubble Space Telescope and of debris disks by ground-based near-infrared interferometers, we have shown the differences in the chemical composition and its homogeneity/inhomogeneity between interstellar dust and dust in comets and debris disks. We conclude from our results that primitive dust particles in comets and debris disks do not originate from prestellar interstellar dust, but from protoplanetary disk condensates.
