Prof. Dr. Yuri Litvinenko von der University of Waikato, New Zealand ist zu Gast bei Prof. Dr. Reinhard Schlickeiser (TP IV). Er hält im Rahmen des Seminars "Weltraum- und Astrophysik" am Mittwoch, 12.11.2014, 10:15 Uhr in NB 7/67 einen Vortrag über “Regular and diffusive photospheric flux cancellation”. Interessierte sind herzlich eingeladen!
Abstract: Photospheric flux cancellation on the Sun is considered. Observations imply that cancellation can be a diffusive rather than regular process. A criterion is derived, which quantifies the parameter range in which diffusive photospheric cancellation should occur. Regular cancellation models are shown to give a quantitatively accurate description of photospheric cancellation. Application of the results to large-scale dispersal of the photospheric magnetic flux is discussed.
