Tracing the origin of the Solar System one isotope at a time” -- by Dr. Reto Trappitsch, LLNL

Understanding the formation and composition of Earth requires knowledge of the building blocks of the Solar System and their dynamics in the solar nebula. Primitive meteorites, which have not been altered during the history of the Solar System, represent valuable samples of these earliest building blocks. They contain the original material the Solar System formed from. Furthermore, these meteorites contain the decay products of short-lived radionuclides and presolar stardust. Both of these indicators represent important signatures to study the evolution of the solar nebula as well as to study how the Solar System’s content formed in the first place. In this talk I will present recent aspects of stardust measurements to decipher galactic chemical evolution, i.e., how the elements that formed the Solar System came together. Furthermore, I will elaborate on our recent measurements on the abundance of 60Fe in the early Solar System and how these measurements inform our understanding of Solar System formation.
