    Constraints on ultralight scalar dark matter with quadratic couplings by Thomas Bouley, Philip Sørensen, Tien-Tien Yu

    Published 2023-03-01

    r-Process elements from magnetorotational hypernovae by Yong, D, Kobayashi, C, Da Costa, GS, Bessell, MS, Chiti, A, Frebel, A, Lind, K, Mackey, AD, Nordlander, T, Asplund, M, Casey, AR, Marino, AF, Murphy, SJ, Schmidt, BP

    Published 2022
    “…Neutron-star mergers were recently confirmed as sites of rapid-neutron-capture (r-process) nucleosynthesis1-3. However, in Galactic chemical evolution models, neutron-star mergers alone cannot reproduce the observed element abundance patterns of extremely metal-poor stars, which indicates the existence of other sites of r-process nucleosynthesis4-6. …”
