Abstract Using self-consistent models of turbulent particle growth in an evolving protoplanetary nebula solar composition, we find that recently proposed local metallicity and Stokes number criteria necessary for the streaming instability to generate gravitationally bound overdensities are generally not approached anywhere disk during first million years, epoch which meteoritic observational ev...

Introduction: Primitive meteorites contain components such as presolar grains and some refractory inclusions that are isotopically different from the average solar system. These isotope anomalies are witness of an initial isotopic heterogeneity of the solar nebula. In spite of this initial isotopic heterogeneity, the isotope composition of larger planetary bodies in the solar system seems to be...
