  1. 1. Orientation of plasma jet fronts in the Earth's magnetotail

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

    Författare :Atlas Silverhult; [2023]
    Nyckelord :Space physics; plamsa; reconnection; magnetospheric multiscale; MMS; magnetosphere; minimum variance analysis; MVA;

    Sammanfattning : This project aims to investigate the orientation of plasma jet fronts in Earth's magnetotail using multi-spacecraft measurement data. The orientations are estimated by applying minimum variance analysis (MVA) and multi-spacecraft timing analysis for finding normal vectors to the jet fronts as they pass over the spacecraft. LÄS MER

  3. 2. Moon plasma environment and its implications for lunar space missions

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Mirko Viviano; [2023]
    Nyckelord :;

    Sammanfattning : This study investigates the lunar plasma environment and its implications for the safety and success of future crewed missions to the Moon. The Moon’splasma environment, formed by the solar wind, galactic cosmic rays and solar flare particles, presents potential hazards to human life and property. LÄS MER

  4. 3. Investigation of inductive electric fields in Earth’s magnetotail using Magnetospheric Multiscale (MMS) multipoint measurements

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Marco Guerra; [2022]
    Nyckelord :;

    Sammanfattning : The mutual interaction between the solar wind and the geomagnetic field generates the magnetosphere. The magnetosphere is characterized by many large-scale perturbations, such as substorms, which are responsible for variations in the magnetic field. LÄS MER

  5. 4. IMF By influence on plasma ion convection in the mid-tail in Earth’s magnetosphere

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

    Författare :Simon Nilsson; [2022]
    Nyckelord :;

    Sammanfattning : The results of past studies indicate that there is an influence of the presence of a nonzero dusk-dawn i.e. y component of the interplanetary magnetic field(IMF By) on the near-Earth magnetotail. Specifically, on the dusk-dawn component (By) of the magnetic field and plasma ion convection, resulting in interhemispheric asymmetries. LÄS MER

  7. 5. Heavy Ion Temperature Anisotropies in the Venus Plasma Environment

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Ville Lindblom; [2021]
    Nyckelord :Space Physics; Plasma; Venus; Heavy Ion;

    Sammanfattning : In a plasma environment particles and plasma waves have complex interactions and can affect each other significantly. The velocity distribution functions (VDFs) can effectively be used to try and understand these interactions. This study uses VDFs to investigate heavy ion temperatures in the Venusian plasma environment. LÄS MER
