Title:     Stardust in the Laboratory: constraints on nucleosynthesis and galactic chemical evolution

Abstract: Meteorites contain presolar stardust - tiny mineral grains that condensed in outflows and explosions of previous generations of stars and survived processing in the interstellar medium and early solar system. They are identified by highly unusual isotopic compositions, reflecting both galactic chemical evolution and nuclear processing in the parent stars, and they thus can provide high-precision constraints on nuclear astrophysics, complementary to traditional astronomical observations. This talk will provide many examples of how meteoritic stardust is providing new insights and quantitative constraints on nuclear processes in the Galaxy.

Stimulants available 15 minutes before the talk.
