The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the suggestion that Ryugu and CI chondrites formed in a different region of the

Origin of isotopic diversity among carbonaceous chondrites

Autor: Hellmann, Jan L., Schneider, Jonas M., Wölfer, Elias, Drążkowska, Joanna, Jansen, Christian A., Hopp, Timo, Burkhardt, Christoph, Kleine, Thorsten

Carbonaceous chondrites are some of the most primitive meteorites and derive from planetesimals that formed a few million years after the beginning of the solar system. Here, using new and previously published Cr, Ti, and Te isotopic data, we show th

Earth's accretion inferred from iron isotopic anomalies of supernova nuclear statistical equilibrium origin

Autor: Hopp, Timo, Dauphas, Nicolas, Spitzer, Fridolin, Burkhardt, Christoph, Kleine, Thorsten

Nucleosynthetic Fe isotopic anomalies in meteorites may be used to reconstruct the early dynamical evolution of the solar system and to identify the origin and nature of the material that built planets. Using high-precision iron isotopic data of 23 i
