  1. 125. Big-Bang Nucleosynthesis Reloaded: Beyond the Lithium Problem?
    Brian Fields (University of Illinois)
    05/09/2022, 16:00
    Invited

    We will summarize the status of big-bang nucleosynthesis (BBN), which describes the production of the lightest nuclides during the first three minutes of cosmic time. We will emphasize the transformational influence of cosmic microwave background (CMB) experiments culminating today with Planck, which pin down the cosmic baryon density to exquisite precision. Standard BBN combines this with...

  2. 107. Gamma-ray lessons about galactic diffuse radioactivities
    Roland Diehl
    05/09/2022, 16:30
    Invited

    Diffuse gamma-ray emission from the decay of radioactive 26Al and 60Fe is a messenger about the nucleosynthesis activity in our current-day galaxy. Because this material is attributed to ejections from massive stars and their supernovae, we can learn from the gamma-ray signal about massive stars and their feedback into surrounding interstellar medium. Our method of population synthesis of...

  3. 46. Galactic Chemical Evolution with radioactive isotopes
    Dr Benjamin Wehmeyer (Konkoly Obs & Univ Hertfordshire)
    05/09/2022, 17:00
    Oral

    In addition to the insights gained by studying the galactic evolution of chemical elements, short lived radioisotopes contain additional information on astrophysical nucleosynthesis sites.
    Meteorites can carry information about the nucleosynthetic conditions in the early Solar System using short lived radioisotopes [1][2], while detections of live isotopes of cosmic origin in the deep sea...

  4. 69. Experimental Study of the 30Si(p,γ)31P for understanding elemental anomalies in Globular Clusters
    Djamila Sarah HARROUZ (IJCLab France)
    05/09/2022, 17:15
    Oral

    Globular clusters are key grounds for models of stellar evolution and early stages of the formation of galaxies. Abundance anomalies observed in the globular cluster NGC 2419, such as the enhancement of potassium and depletion of magnesium [1] can be explained in terms of an earlier generation of stars polluting the presently observed stars [2]. However, the nature and the properties of the...
