Summary
Nucleosynthetic and radiogenic isotope data from meteorites have significantly advanced the understanding of how the protoplanetary disk was structured during the accretion of planetary precursors. Meteorites exhibit an isotopic dichotomy between carbonaceous (CC) and non-carbonaceous (NC) meteorites. This NC–CC dichotomy, combined with the chronology of meteorite parent body accretion, implies a potentially strict spatial divide between the inner (NC) and outer (CC) protoplanetary disk which lasted several million years. This divide may have been facilitated by early formation of the gas giant planets, which acted as a barrier, thereby significantly influencing the chemical evolution of the disk and thus the planet building process. These meteorite-derived findings and their implications for planet evolution are discussed here, with an emphasis on the role that Vesta and Ceres play in piecing together the history of the Solar System, as these bodies may be considered as samples of the inner and outer protoplanetary disk, respectively.
