  1. 1. On The Run: How Fast Runaway Stars Can Escape From Their Home Cluster?

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Anna-Maria Söderman; [2022]
    Nyckelord :star cluster; runaway stars; velocity distribution; Physics and Astronomy;

    Sammanfattning : Galaxies contain a wide variety of star clusters with different properties. Each cluster is a possible source of runaway stars, which can be progenitors of supernovae in other parts of the galaxy than their home cluster. Considering runaway stars in galaxy simulations has shown to increase the galactic feedback. 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

  4. 3. How Odd is Betelgeuse?

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Martin Oshaughnessy; [2020]
    Nyckelord :Betelgeuse; runaway stars; stellar evolution; binary interactions; Physics and Astronomy;

    Sammanfattning : The role of massive stars (those with masses greater than eight solar masses) in the chemical enrichment of galaxies and renewed star formation forms an important field of fundamental research in modern astrophysics. The complex nature of massive star evolution produces formidable challenges in furthering our understanding of the processes driving massive star evolution. LÄS MER

  5. 4. The Stability of Exomoons in the Habitable Zone

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Henrik Nordanger; [2014]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : This is an analysis of all the planets at exoplanets.org, with the goal of finding out how many of these that could possibly have moons supporting life. LÄS MER
