  1. 1. Possible Bow Shock Current Closure to Earth's High Latitude Ionosphere on Open Field Lines

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Gabriella Nordin; [2023]
    Nyckelord :Space Physics; Bow Shock Current; Field-Aligned Currents; Open Field Lines;

    Sammanfattning : The bow shock is formed due to the abrupt deceleration of the supersonic solar wind in front of the terrestrial magnetic field. The solar wind plasma and the Interplanetary Magnetic Field (IMF) are both compressed across the shock, and according to Ampère's law a current thus flows on the bow shock at all times. LÄS MER

  3. 2. Space Weather Simulation Model Integration

    Magister-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Alice Molin; Julia Johnstone; [2023]
    Nyckelord :simulation model; OpenSpace; GAMERA; HDF5; NASA; space weather; magnetosphere; field lines; cut plane; curvilinear grids; data extraction; integration; visualization; hierarchical data format; textures; transfer function; Medicinsk teknik; Medicinsk teknik;

    Sammanfattning : Space weather is the field within the space sciences that studies how the Earths magnetosphere is influenced by the Sun. The Sun is constantly emitting dangerous radiation and plasma which in some cases can affect or damage the systems on Earth. LÄS MER

  4. 3. Hur gammal är jordens inre kärna?

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Tim Bergström; [2023]
    Nyckelord :Inner core; thermal conductivity; convection; Earth’s magnetic field; paleomagnetism; Earth and Environmental Sciences;

    Sammanfattning : Åldern för jordens inre kärna är en gåta som har förbryllat forskare i många decennier. Allt från en ålder lika hög som jordens magnetfält (mellan 3,5 och 4,2 Ga) i den ena änden, ner till 0,5 Ga i den andra änden. LÄS MER

  5. 4. Real-time Field Line Rendering for Temporal and Heliophysical Datasets

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Christoffer Paulusson; [2022]
    Nyckelord :field lines; fieldlines; rendering; temporal; heliophysical; real-time; OpenSpace; NASA; visualization;

    Sammanfattning : The thesis compares two different methods for tracking and moving field lines. The first method included tracing one field line and moving each individual vertex along its own path with path following. The second method was done by tracing new field lines and using linear interpolation to move the field lines. LÄS MER

  7. 5. Visualising earth's magnetosphere interacting with the solar wind using numerical methods and semi-transparent surfaces

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Rickard Elfström; [2022]
    Nyckelord :Data visualization; Visualization; OpenSpace; numerical methods; Space; Earth s magnetosphere; Solar wind;

    Sammanfattning : Data visualization is a field dedicated to effectively showing large amounts of collected data. A field where data visualization has shown promising results in its ways to effectively answer questions is the fundamental research of the universe. LÄS MER
