Description
Signatures of stellar material affected by neutron-capture processes were not completely diluted in the early Solar System and are still found recorded in meteorites. These fingerprints of neutron captures range from radioactive isotopes produced by neutron captures, to stardust from asymptotic giant branch stars and core-collapse supernovae, as well as widespread highly diluted, but still measurable, anomalies in the isotopic abundances of refractory elements, from Mo and Ru to Cr and Ti. I will review the status of such observations and what they can tell us about the formation of the Sun, the evolution of its proto-planetary disk, and the formation of our planetary system.
