Minerals preserve records of the physical, chemical, and biological histories of their origins
and subsequent alteration, and thus provide a vivid narrative of the evolution of Earth and …

Raman analyses are reported of μm-sized areas of 103 individual carbonaceous presolar
grains (“graphite grains”) from three different density fractions of the Murchison meteorite …

We report on the results of NanoSIMS isotope imaging of low-density supernova graphite
grains from the Orgueil meteorite. 70 nm thick microtomed sections of three supernova …

Primitive meteorites contain tiny dust grains that condensed in stellar outflows and
explosions. These stardust grains can be extracted from their host meteorites and studied in …

Tiny dust grains extracted from primitive meteorites are identified to have originated in the
atmospheres of stars on the basis of their anomalous isotopic compositions. Although …
