Convection and Magnetic Field Generation in Rotating Spherical Fluid Shells
… mechanisms believed to be responsible for the generation and the variations in time of the main geomagnetic field. Questions such as linear onset and nonlinear finite-amplitude properties of rotating convection, generation and equilibration of magnetic fields in electrically conducting fluids, …

Experimental Studies of Magnetic Field Generation and Saturation Mechanisms in Laser-Driven Plasmas
… improved ability to discern between electric and magnetic fields. This new backlighter is well-suited for NIF experiments, where large fields and plasma densities often preclude useful 3.0 MeV proton data. The advantages are demonstrated with radiographs of OMEGA plasmas with magnetic and electric …

Shear instabilities in stellar objects: linear stability and non-linear evolution
… in turbulent motions, mixing processes, and magnetic field generation, are not entirely understood. It is therefore necessary to investigate the inevitable small-scale dynamics via numerical calculations. In particular a thin region with strong shear at the base of the convection zone in the …

Neutron Star Electromagnetic Field Structure
… dissertation investigates the neutron star magnetic field from generation to radiation production. We have investigated the spontaneous magnetization process to explain the magnetic field generation. This magnetization is then applied to determine the electromagnetic field structure of the …

Helical waves in Earth's outer core
This thesis addresses the generation and dispersion of wave packets in Earth's outer core. The waves of interest feed off the buoyancy field, and are supported by strong rotation and/or a large-scale magnetic field, two key features of the dynamics in Earth's core. We aim to better understand the …

Zum Dynamoeffekt in extern getriebenen Strömungen
Die Frage nach der Herkunft und der dynamischen Entwicklung langlebiger kosmischer Magnetfelder ist in vielen Details noch unbeantwortet. Es besteht zwar kein Zweifel daran, dass das Magnetfeld der Erde und anderer kosmischer Objekte durch den sogenannten Dynamoeffekt verursacht werden, der genaue …
