  1. 1. Towards Automatic Model Atoms from the VALD Atomic Database: from He to U

    Kandidat-uppsats, Uppsala universitet/Teoretisk astrofysik

    Författare :Samuel Hermansson; [2023]
    Nyckelord :r-process; nucleosynthesis; kilonovae; VALD;

    Sammanfattning : The ejecta following the collision and merging of two neutron stars (kilonova) are currently considered promising sites for nucleosynthesis of r-process elements. Since the observed kilonova in 2017, GW2017817, astrophysicists have been working to analyze the collected electromagnetic spectra, trying to identify r-process elements. LÄS MER

  3. 2. Exploring the application of neural networks in predictions of nuclear binding energies

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Martin Waites; [2020]
    Nyckelord :neural networks; drip-line; nuclear physics; binding energy; exotic nuclei; Hartree-Fock-Bogolyubov; Physics and Astronomy;

    Sammanfattning : In this project the locations of the proton and neutron drip-lines are predicted using neural networks and theoretical data obtained by applying the HFBTHO program. For each of the neural networks a comparison is made between neural network predictions and experimental data in the region experimental data exists. LÄS MER
