Das Institut für Physik Institutsbereich Geophysik, Astrophysik und Meteorologie lädt zu folgendem
Vortrag im Rahmen des Astrophysikalischen Kolloquiums ein:
Modelling solar and stellar activity from the dynamo to the corona
Dr. Jörn Warnecke
Max Planck Institut für Sonnensystemforschung, Göttingen, Germany
Jörn Warnecke will present results of 3D MHD models of convective dynamos operating in solar-like stars, of solar and stellar coronae and as well the results of simplified combined dynamo-corona models to discuss the important aspect of modelling solar and stellar activity. This includes the questions: How does the solar activity fit into the stellar context? What is the effect of magnetic helicity in connecting the magnetic field generation below the surface and violent eruption above the surface? What are the main processes describing the stellar rotation-activity relation? How does future solar and stellar observations help us in understanding the processes of solar and stellar activity?
