Scientific scope

The physical understanding of our Sun is in many ways foundation science. Its applications range from the Sun as a calibrated neutrino source, as a laboratory for reactions and decays of light nuclei under plasma conditions and for magnetohydrodynamical processes, to its function as a benchmark for stellar models: Stellar structure, evolution, and seismology can be precisely tested against data from the well-observed Sun. Advanced telescopes and space missions aided by theoretical modelling study the processes that are involved in the continuous reconfiguration of the Sun’s magnetic field on the surface and the atmosphere. A continuous solar wind of particles fills interplanetary space, while coronal mass ejections lead to solar storms, posing risks to technology in near-Earth space or on ground. A large number of space missions have advanced our knowledge on the Sun and its influence on the planetary system. Scientists in Germany and Spain have for many years been at the forefronts both of the physics of the solar core (neutrinos and nuclear reactions) and phenomena from the solar interior via the surface to the solar wind. However, these research fields have developed and prospered largely in parallel, with limited interaction. The present workshop aims to bridge this gap and assemble a core group of scientists working on all physical aspects of the Sun. The main concepts of each branch of solar research shall be laid out in dedicated lectures. There shall be ample space for free discussion, with the aim of discovering new interdisciplinary research avenues to address the Interdisciplinary Physics of the Sun.
