Dynamics of the rise of magnetic flux tubes in stellar interiors
In sonnenähnlichen Sternen erhält ein Dynamo-Mechanismus die Magnetfelder. Der Babcock-Leighton-Dynamo beruht auf einem solchen Mechanismus und erfordert insbesondere die Existenz von magnetischen Flussröhren. Man nimmt an, dass magnetische Flussröhren am Boden der Konvetionszone entstehen und …

Generation and propagation of longitudinal tube waves in late-type stellar atmospheres and the rotation-emission activity relation
Generated longitudinal tube wave (LTW) energy fluxes as a result of the interaction of magnetic flux tubes with the turbulent medium of the convection zones of late-type stars were computed. Solar magnetic flux tubes of different filling factors were heated with adiabatic and radiatively damped …

Genesis, dynamics, and dissipation of turbulent magnetic fields
… indicate that coherent, dynamically important magnetic fields are ubiquitous in the Universe. However, neither the origin problem—what are the physical mechanisms that generate the initial ``seed'' magnetic fields—nor the dynamo problem—how magnetic fields are amplified and sustained by …

Determing the Properties of Dense Matter: Superconductivity, Bulk Viscosity, and Light Reflection in Compact Stars
… We then calculate the structure of magnetic flux tubes, taking into consideration interactions between neutron and proton Cooper pairs. We find that interactions between the condensates can lead to interesting phenomena and new phases at the border between type-I and type-II …

The origin and dynamic interaction of solar magnetic fields
… of the solar corona are dominated by the magnetic field which creates its structure. The magnetic field in most of the corona is ?frozen? to the plasma very effectively. The exception is in small localised regions of intense current concentrations where the magnetic field can slip through …

Relationship between photospheric magnetic fields and coronal activities
… known to be related to the evolution of surface magnetic fields. This dissertation studies the evolution of photospheric magnetic fields and flow fields and their relation to the properties of these two coronal emission components. The key issue in the study of the steady coronal emission is the …
