  1. 31. Motion of icy grains originating in Saturn’s D-ring

    L3-uppsats, Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen; Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Apostolos Kolokotronis; [2023]
    Nyckelord :;

    Sammanfattning : Saturn's rings have long been thought to provide the planetary atmosphere with infalling material, affecting both its chemical composition and physical properties (e.g. temperature). LÄS MER

  3. 32. Fractional Habitability comparison of slow rotating Earth-like bodies

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Gustaf Gothefors-Holm; [2023]
    Nyckelord :habitability; General circulation model; climate modelling;

    Sammanfattning : ROCKE-3D is a contemporary Global Circulation Model allowing research into the complex processes behind the climate of planets. Using ROCKE-3D one can construct a model coupling atmosphere, land, and ocean revealing how the climate of a planet evolves over time. LÄS MER

  4. 33. Testing the detectability of supernova ejecta from Population III stars with future ELT/ANDES

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Aron Kordt; [2023]
    Nyckelord :;

    Sammanfattning : The first stars, known as Population III (Pop III) stars, formed when the Universe was about 100 Myr to 200 Myr old. In contrast to the present-day Universe, star formation took place in a basically metal-free environment. Despite several decades of research, Pop III stars have not yet been directly observed.

  5. 34. Magnetic field of the Ap star EP UMa

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Jakob Melin; [2023]
    Nyckelord :stars: chemically peculiar - stars: magnetic fields – stars: individual: EP UMa;

    Sammanfattning : Magnetic fields play a crucial roll in the stellar activity and evolutionof stars. Despite much research there is much that we do notunderstand. Among Ap stars, empirical evidence has suggested a minimumthreshold for the dipolar magnetic field strength of Bp ≈ 300G. LÄS MER

  7. 35. The Quantum Approximate Optimization Algorithm and it's Applications

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Erik Bashore; [2023]
    Nyckelord :Quantum computing; quantum optimization; combinatorial optimization problems;

    Sammanfattning : This is a project with the ambition of demonstrating the possibilities and applications of the quantum approximation optimization algorithm (QAOA). Throughout the paper discussions on the theoretical background and fundamentals of the algorithm will be done by examining the relevant nomenclature. LÄS MER
