Abstract
Primitive meteorites contain grains that originated in stellar outflows and supernova ejecta prior to the formation of the solar system. The study of these presolar grains, whose stellar origin is indicated by their anomalous isotopic compositions, requires the combined efforts of scientists from different disciplines, including nuclear astrophysics, observational astronomy and cosmochemistry. Presolar grains provide new information on galactic evolution, the age of the galaxy, stellar evolution, nucleosynthesis, mixing in supernovae, the composition of stellar atmospheres, and processes on meteorite parent bodies.Keywords
