Solar Magnetic Fields

range of topics in the field of solar magnetism, including photospheric, chromospheric and coronal magnetic fields and their dependence on the solar activity cycle. He has published over 50 scientific papers on the observation and interpretation of solar magnetic measurements, in particular on the changes that lead to the evolution of solar activity both on the surface and in the solar atmosphere. His work has connected solar magnetic fields to heliospheric phenomena, in particular to the solar wind, Coronal Mass Ejections and the heliospheric magnetic field.Sami Solanki is Director of the Max Planck Institute for Solar System Research (MPS) in Gottingen, Germany. He is a leading figure in solar physics in general an solar magnetism in particular through his active leadership of both experimental and analytical aspects of international solar research projects, such as GREGOR, a 1.5-m solar telescope operated on Tenerife, the SUNRISE balloon-borne solar telescope and the Polarimetric and Helioseismic Imager instrument to be flown on the Solar Orbiter Mission of the European Space Agency. He is the author of several hundred scientific papers on solar and heliospheric topics and the speaker at the International Max Planck Research School for Solar System Science at the University of Göttingen. He is Editor-in-Chief of the online review journal Living Reviews in Solar Physics and he holds professorial appointments at the at the Eidgenössische Technische Hochschule, Zürich and at the Technische Universität Braunschweig. Michael Thompson is the Deputy Director and Chief Operating Officer of the National Center for Atmospheric Research (NCAR), and an NCAR Senior Scientist. From 2010 to 2014 he was Director of the High Altitude Observatory and an Associate Director of NCAR. Prior to joining NCAR, Michael was Head of the School of Mathematics and Statistics in the University of Sheffield, United Kingdom, and was formerly a Professor of Physics at Imperial College London. Dr. Thompson's scientific research activity is principally in helioseismology, asteroseismology, solar physics, and inverse problems. He has worked extensively in developing and applying inverse techniques in helioseismology, and in particular measuring the stratification, rotation, and large-scale flows in the solar interior. Dr. Thompson has published widely on the interpretation of helioseismologic observations that have brought new insights into the origin and evolution of solar magnetic fields.Rudolf von Steiger holds an MSc in theoretical physics (1984), a PhD in experimental physics (1988), and a habilitation in extraterrestrial physics (1995) from the University of Bern. He was a CoI of the Solar Wind Ion Composition Experiment (SWICS) on Ulysses and an associated scientist of the AMPTE and ACE missions. His relevant experience includes theoretical modelling of solar chromospheric processes, specifically of the FIP fractionation effect, as well as the analysis and interpretation of solar wind observations both in the Earth's magnetosheath and in interplanetary space. In 1995 he joined the newly created International Space Science Institute (ISSI) in Bern as senior scientist. Since 1999 he is a director there and also holds an associate professorship at the University of Bern. He serves as an editor of Space Science Reviews, Frontiers in Space Science, and Living Reviews in Solar Physics.
