2. 1. Solution-Chemically Derived Spectrally Selective Solar Absorbers : With System Perspectives on Solar Heating

   Author : Tobias Boström; Ewa Wäckelgård; Gunnar Westin; Björn Karlsson; Peter Lund; Uppsala universitet; []
   Keywords : Materials science; solar; thermal; absorber; selective; chemical; Materialvetenskap;

   Abstract : This thesis consists of two parts, one dominating part concerning spectrally selective solar absorbers and one dealing with thermal solar systems. The appended papers I to VIII concern the solar absorber part, papers dealing with the systems part have not been included in the thesis. READ MORE

6. 4. Measuring the solar atmosphere

   Author : Jaime de la Cruz Rodríguez; Göran Scharmer; Dan Kiselman; Mats Carlsson; Gianna Cauzzi; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sun; Chromosphere; Spectropolarimetry; Solar observations; Spectral lines; Solar magnetic fields; Astronomy; Astronomi; Astronomy; astronomi;

   Abstract : The new CRISP filter at the Swedish 1-m Solar Telescope provides opportunities for observing the solar atmosphere with unprecedented spatial resolution and cadence. In order to benefit from the high quality of observational data from this instrument, we have developed methods for calibrating and restoring polarized Stokes images, obtained at optical and near infrared wavelengths, taking into account field-of-view variations of the filter properties.

7. 5. Combining Models of Coronal Mass Ejections and Solar Dynamos

   Author : Jörn Warnecke; Axel Brandenburg; Juri Toomre; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetohydrodynamics; convection; turbulence; solar dynamo; solar rotation; solar activity; coronal mass ejections; Astronomy; astronomi;

   Abstract : Observations show that Coronal Mass Ejections (CMEs) are associated with twisted magnetic flux configurations. Conventionally, CMEs are modeled by shearing and twisting the footpoints of a certain distribution of magnetic flux at the solar surface and letting it evolve at the surface. READ MORE
