  1. 100. The chemical composition of the Solar System
    Katharina Lodders (Washington University)
    28/06/2018, 09:15
    Invited
    The stage for studying element and isotopic distributions with the goal to understand the origin of the chemical elements was set about a century ago when it was already recognized that meteorite compositions can provide clues, and when Russell (1929) did the first comprehensive quantitative analyses of elements on the photosphere and found that abundances of non-volatile elements in...

  2. 181. Nucleosynthetic fingerprints in meteorites and planets
    Maria Schönbächler (ETH Zurich)
    28/06/2018, 09:45
    Invited
    During the past decade, it has been well established that virtually each planetary body in our solar system carries its own distinct nucleosynthetic isotope compositions. The variable compositions represent the heterogeneous distribution of presolar nm-to-µm size dust grains in our Solar System. While they were destroyed in most planetary bodies, primitive meteorites preserved these dust...

  3. 145. The Abundance of 60Fe in the Early Solar System
    Reto Trappitsch (Lawrence Livermore National Laboratory)
    28/06/2018, 10:15
    Oral
    The abundance of the extinct radionuclide 60Fe (2.62 Myr half-life) in the early Solar System is highly disputed in the literature. On one hand, bulk measurements of early Solar System materials indicate an initial abundance consistent with galactic background [1, 2]. On the other hand, in situ studies by secondary ion mass spectrometry (SIMS) report a variety of ratios, e.g., [3], including...

  4. 199. Isotopic compositions of trace elements in presolar SiC: new constraints on stellar nucleosynthesis
    Andrew Davis (University of Chicago)
    28/06/2018, 10:30
    Oral
    The isotopic compositions of trace elements in presolar grains provide unique constraints on stellar nucleosynthesis. The CHicago Instrument for Laser Ionization (CHILI) [1] is a laser resonance ionization mass spectrometer with unprecedented sensitivity and control of isobaric interferences, and 1ne lateral resolution, built primarily for applications in cosmochemistry. CHILI has recently...

  5. 25. Short-lived radionuclei as clocks for the prehistory of the Solar System
    Maria Lugaro (Konkoly Observatory, Hungary)
    28/06/2018, 10:45
    Oral
    While we know that stars are born in groups (clusters) within stellar nurseries, i.e., (possibly giant) molecular clouds, perhaps surprisingly, we do not have any consensus on the type of stellar nursery and stellar cluster where our Sun was born. Radioactive nu- clei with half-lives between roughly 10 and 100 Myr were present in the early Solar Sys- tem, as indicated by high-precision...
