1. 1. Oscillations in a complex sunspot: From theory to data

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Femke Kranenbarg; [2024]
   Keywords : ;

   Abstract : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

3. 2. Seeing Stars - Intensity Interferometry in the Laboratory and on the Ground

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Colin Carlile; [2021]
   Keywords : Stellar Physics Instrumentation Interferometry Cherenkov Telescope Array Intensity Interferometry; Physics and Astronomy;

   Abstract : Context Since the time of Tycho Brahe astronomy has been an observing science defined by the quality of its instrumentation. The introduction of primitive telescopes by Galileo in 1609 began a period of development of ever-larger telescopes with greater measuring precision. READ MORE

4. 3. Regional and Local Factors Influencing the Mass Balance of the Scandinavian Glaciers.

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Höglin David; [2016]
   Keywords : Glacier; climate; mass balance; PCA.; Glaciär; klimat; massbalans; PCA.;

   Abstract : According to climatic models there will be an increase in the amount of greenhouse gases which results in a warming of the earth where the change will be most prominent in the high latitudes. Glaciers mass balance is a good climate change indicator as the response is fast when climate is changing. READ MORE

5. 4. Radiocarbon around the Carrington event

   University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Damien Pierce; [2016]
   Keywords : Physics and Astronomy;

   Abstract : 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. READ MORE

6. 5. Inference of chromospheric magnetic fields with the Ca II 8542 line

   University essay from Uppsala universitet/Teoretisk astrofysik

   Author : Filip Jennerholm Hammar; [2014]
   Keywords : Sun: chromosphere; Sun: magnetic topology; polarization; weak field approximation;

   Abstract : Several techniques exist for retrieving and studying information about the properties of the Solar atmosphere from the polarization state of spectral lines. These are commonly called spectral diagnostics. READ MORE
