  1. 1. Zeeman Doppler Imaging of the eclipsing binary UV Piscium

    Master-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :Axel Hahlin; [2020]
    Nyckelord :Magnetic fields; polarisation; eclipsing binary;

    Sammanfattning : Magnetic fields are important for multiple physical processes in and around stars, for these reasons improving the understanding of how they are generated and maintained is of great value. In this work the magnetic field structure of the eclipsing binary UV Piscium is investigated. LÄS MER

  2. 2. Coupled waves as a model to describe chaotic turbulence pumped by radio waves in the ionosphere

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

    Författare :Axel Hahlin; [2018]
    Nyckelord :turbulence; coupled waves; plasma;

    Sammanfattning : Experimental results concerning plasma turbulence pumped in theionosphere by powerful radio waves suggest that the turbulence is due todeterministic chaos. To investigate the possibility of deterministic chaosin the ionosphere coupled wave systems have been studied to see chaoticdynamics. LÄS MER
