Magneto-static modelling from Sunrise/IMaX — •Thomas Wiegelmann1, Thomas Neukirch2, Dieter Nickeler3, Sami Solanki1,4, and Sunrise Team11Max-Planck-Institut für Sonnensystemforschung, 37077 Goettingen — 2School of Mathematics and Statistics, University of St. Andrews, UK — 3Astronomical Institute, AV CR, Fricova 298, 25165 Ondrejov, Czech Republic — 4School of Space Research, Kyung Hee University, Yongin, Gyeonggi, 446-701, Republic of Korea

Our motivation is modelling the interface region between solar photosphere and corona. We extrapolate Sunrise/IMaX photospheric magnetic field measurements upwards into the chromosphere and corona. A problem is that the interface layer is very complex. Relative importance of magnetic and plasma forces vary over several orders of magnitude. In the magneto-static approach the Lorentz-force is compensated by the plasma pressure gradient force and the gravity force.
