![]() The distinct and unique isotopic compositions of bulk meteorites and their individual components allow the investigation of genetic relationships among them.įigure 1: Artist’s impression of the early Solar System as the solar nebula gas begins to disappear, causing asteroids to accelerate and collide. ![]() Bodies accreted in different regions in the solar nebula and, therefore, inherited the local isotopic signatures. These isotopic variations reflect the isotopic heterogeneity (carried by presolar dust) that was present in the protoplanetary disc during the period of planetary formation (Figures 1 and 2). Nucleosynthetic isotopic analyses of elements such as Ca, Ti, Cr, Ni, Zr, Mo and Pd reveal variations among different solar system materials. ![]() Nucleosynthetic isotope compositions in solar system materials The data will also serve as detailed constraints for protoplanetary disc and planet formation models (Projects A3/WP1 and A5/WP3). This project aims to obtain new cosmochemical data from meteorites to provide physical evidence for the processes acting at the different stages of planet formation. Understanding the processes that lead to the formation of planets and their diverse compositions is one of the key goals of the NCCR PlanetS and still contains many uncertainties.
