1. 1. Magnetic field of the Ap star EP UMa

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Jakob Melin; [2023]
   Keywords : stars: chemically peculiar - stars: magnetic fields – stars: individual: EP UMa;

   Abstract : Magnetic fields play a crucial roll in the stellar activity and evolutionof stars. Despite much research there is much that we do notunderstand. Among Ap stars, empirical evidence has suggested a minimumthreshold for the dipolar magnetic field strength of Bp ≈ 300G. READ MORE

3. 2. CFD Analysis of Water Replenishment Holes in an Offshore Wind Turbine Foundation

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Shubham Arvind Tupkar; Swetha Sappe Narasimhamurthy; [2022]
   Keywords : CFD; Wave Dynamics; Implicit LES; GABC; OpenFOAM; Stokes V; Monopile Foundation; Replenishment Holes;

   Abstract : The study presented in this thesis investigates the passive exchange of enclosed water with seawater in an offshore wind turbine foundation. This thesis was undertaken in collaboration with Vattenfall R&D, Älvkarleby, Sweden. The water exchange is studied by utilizing Computational Fluid Dynamics (CFD) simulations. READ MORE

4. 3. The magnetic fields of exoplanet hostM-dwarf stars : The magnetic fields of exoplanet hostM-dwarf stars

   University essay from Uppsala universitet/Teoretisk astrofysik

   Author : Thomas Herard; [2021]
   Keywords : ;

   Abstract : The majority of stars in the Milky Way are M dwarfs whichmake up 75 % of stars in the vicinity of the sun. As the magneticfield of stars can significantly affect the interiors and theatmospheres of the exoplanets they host within the stellar system,characterising this magnetic field is of major importance.

5. 4. Investigation of the magnetic fields of a young Sun-like star ∏1 UMa

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Lawen Ahmedi; [2020]
   Keywords : Magnetic field; star; young Sun; polarisation; Stokes vector;

   Abstract : In astronomy, the Sun has an important role. It keeps the solar-system together and is thesource for life, heat, light and energy to Earth. As any other star or planet, the Sun has amagnetic field. The magnetic field of the Sun has a great impact on the Sun itself as well asits surrounding. READ MORE

6. 5. Formation of Eu II spectral features in magnetic chemically peculiar stars

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Luca Schmidt; [2020]
   Keywords : ;

   Abstract : The advancing resolution of modern spectrometers uncovers increasingly detailed spectral features in astrophysical observations which can be attributed to properties of the energy structure of the corresponding atomic systems such as fine, hyperfine and Zeeman splitting. At the same time, increasing computational power enables us to include these quantum mechanical interactions on different levels of sophistication in our theoretical atomic structure calculations.
