  1. 1. An analysis of the turbulent properties of a CME

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

    Författare :Roque Márquez Rodríguez; [2022]
    Nyckelord :CME; turbulence; plasma; solar wind; MHD;

    Sammanfattning : Spectral indices and flatness scaling exponents corresponding to solar wind plasma measurements before, during and after a coronal mass ejection (CME) detected by NASA's Wind spacecraft on September 2014 have been obtained. The Politano-Pouquet (PP) law for isotropic and incompressible magnetohydrodynamic (MHD) turbulence has been validated over a series of selected time intervals. LÄS MER

  3. 2. Interpreting density enhancement of coronal mass ejections

    Kandidat-uppsats, Uppsala universitet/Rymd- och plasmafysik

    Författare :Kellen Smith; [2019]
    Nyckelord :physics; astrophysics; coronal mass ejection; WSA-ENLIL Cone; arrival time; prediction; model parameters; fysik; astrofysik; koronamassutkastning; WSA-ENLIL Cone; ankomsttid; prognos; modellparametrar;

    Sammanfattning : Coronal mass ejections (CMEs) are some of the extraterrestrialevents most impactful to earth. Eorts to model and predict theireects have seen new possibilities in the two most recent decades dueto multiple new spacecrafts providing a wider range of data than everbefore. LÄS MER

  4. 3. Radiocarbon around the Carrington event

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Damien Pierce; [2016]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The Sun is a volatile and complex body, understanding its behaviour is key to the continued operation of modern technology. The Carrington event was a violent white light event and generally believed to have lead to one of the largest solar storms in modern human history. LÄS MER

  5. 4. Interactive visualization of space weather data

    Master-uppsats, Medie- och Informationsteknik; Tekniska högskolan

    Författare :Martin Törnros; [2013]
    Nyckelord :scientific visualization; volumetric rendering; ray casting in spherical coordinates; space weather; sun; coronal mass ejection; cme; NASA; Datateknik; Datateknik;

    Sammanfattning : This work serves to present the background, approach, and selected results for the initial master thesis and prototyping phase of Open Space, a joint visualization software development project by National Aeronautics and Space Administration (NASA), Linköping University (LiU) and the American Museum of Natural History (AMNH). The thesis report provides a theoretical introduction to heliophysics, modeling of space weather events, volumetric rendering, and an understanding of how these relate in the bigger scope of Open Space.
