  1. 1. Investigation of recovery of stellar magnetic field geometries from simulated spectropolarimetric data

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Ahmed Al Kanale; [2017]
    Nyckelord :Magnetic Doppler Imaging MDI code INVERS10;

    Sammanfattning : Powerful remote sensing techniques can covert time variability of polarization profiles of stellar spectral lines into vector magnetic fields maps of stellar surfaces. These techniques are widely applied to interpret observations but have been tested using only simplistic tests. LÄS MER

  3. 2. Imaging stellar surfaces with intensity interferometry

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

  4. 3. A Hundred Times Sharper Than Hubble: Stellar imaging with intensity interferometry

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Hannes Jensen; [2010]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Imaging of stellar surfaces in visible wavelengths is one of the current frontiers in astronomy. With a few exceptions, stars can not be seen in visible light as anything but point objects with current technology. LÄS MER
