Invited Talk

The chemical composition of our Solar System reflects Galactic chemical evolution (GCE) in the local interstellar medium (ISM) over the past ~9 Ga. While the incorporated ISM dust was mostly destroyed during the Solar System formation, a small fraction of the ISM dust, known as presolar grains, is preserved in pristine extraterrestrial materials and identified by their exotic isotopic...
