  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. Statistics of Electric and Magnetic Fields at the Earth’s Bow Shock

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

    Författare :Tsz-Kiu Wong-Chan; [2023]
    Nyckelord :MMS; Earth’s bow shock; Collisionless shocks; Correlation study; statistics; Space; Space plasma physics; MMS; Jordens bogchock; Kollisionsfria chocker; Korrelationsstudie; Statistik; Rymd; Rymdplasmafysik;

    Sammanfattning : The interaction between the solar wind and Earth’s magnetic field creates the Earth’s bow shock. It is an ideal region for space probes like MMS, THEMIS or Clusters to study the collisionless shock phenomenon in space plasma. LÄS MER

  4. 3. Study and characterization of energetic particles from the solar wind entering the magnetosheath region

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

    Författare :Farid Hedayati; [2022]
    Nyckelord :Magnetospheric Multiscale Mission MMS ; Magnetosheath classification; Particles; Time series analysis; Space plasma physics;

    Sammanfattning : The emphasis of the thesis is on understanding how the high-energy particles of the foreshock are transmitted into the magnetosheath and how this process can be used to specify the conditions upstream of the bow shock with the help of local magnetosheath measurements. In this study, through analyzing the data from the MMS satellites, I try to draw a connection between the flux and wind direction related to Earth’s bow shock. LÄS MER

  5. 4. Automatic SLAMS detection and magnetospheric classification in MMS data

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

    Författare :Carl Foghammar Nömtak; [2020]
    Nyckelord :Short Large-Amplitude Magnetic Structures SLAMS ; Algorithm design; Magnetospheric classification; Time series analysis; Space plasma physics; Korta magnetiska strukturer med hög amplitud SLAMS ; Algoritmdesign; Magnetosfärsklassificering; Tidsseriesanalys; Rymdplasmafysik;

    Sammanfattning : Short Large-Amplitude Magnetic Structures (SLAMS) have been observedby spacecraft near Earth’s quasi-parallel bow shock. They arecharacterized by a short and sudden increase of the magnetic field,usually by a factor of 2 or more. LÄS MER

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

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

    Författare :Alexander Bader; [2017]
    Nyckelord :Venus; magnetospheric physics; plasma wave; ion distribution; anisotropy; temperature;

    Sammanfattning : Velocity distributions are a key to understanding the interplay between particles and waves in a plasma. Any deviation from a Maxwellian distribution may be unstable and result in wave generation. LÄS MER
