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. An analysis of the turbulent properties of a CME

   University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Roque Márquez Rodríguez; [2022]
   Keywords : CME; turbulence; plasma; solar wind; MHD;

   Abstract : 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. READ MORE

4. 3. On the Interaction Between Electromagnetic, Gravitational, and Plasma Related Perturbations on LRS Class II Spacetimes

   University essay from Umeå universitet/Institutionen för fysik

   Author : Philip Semrén; [2021]
   Keywords : ;

   Abstract : In this thesis, we investigate the interaction between electromagnetic, gravitational, and plasma related perturbations on homogeneous and hypersurface orthogonal Locally Rotationally Symmetric (LRS) class II spacetimes. By using these spacetimes, which allow for the inclusion of a non-zero magnetic field, as backgrounds in a perturbative approach, we are able to see interactions between the electromagnetic and gravitational variables already to first order in the perturbations.

5. 4. Feasibility study of Magnetic Flow Meters for Molten Salt Reactors

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Sebastian Nilsson; [2020]
   Keywords : Nuclear Engineering; Molten Salt Reactors; Magnetic Flow Meters;

   Abstract : This thesis investigates the possibility of using magnetic flow meters to measure the flowrate of molten salts in Seaborg Technologies Compact Molten Salt Reactor (CMSR).There is a need to accurately measure the flow rate in salt circulation systems to ensureproper operation of the entire facility.

6. 5. Reconstructing ICMEs with the toroidal Grad-Shafranov method

   University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Moa Skan; [2019]
   Keywords : space physics; plasma; coronal mass ejections; interplanetary coronal mass ejections;

   Abstract : The main objective of this thesis is to model the magneticstructure of interplanetary coronal mass ejections (ICME) measuredin-situ from the WIND spacecraft positioned at L1. The modeling isdone by a magnetohydrodynamic reconstruction technique based onthe GS equation with a toroidal geometry. READ MORE
