Constraining Solar System and Earth Building Blocks Through Isotopic Analysis of Meteorites In order to constrain the formation and evolution of the Solar System and Earth, it is necessary to identify their stellar building blocks. The isotopic compositions of extraterrestrial material provides insights into what these building blocks may be. Heavy elements (Z > 26) are produced in certain types of stars and high-energy stellar events. Evaluating the heavy element composition of meteorites, and their constituent “star dust”, can help determine the stellar sources that contributed to the Solar System. Meteoritic samples can also be compared with terrestrial samples to draw inferences about Earth’s accretion history. We present exciting results that may indicate a new event in this history, with implications for the origin of organic matter on Earth.
