Magnetohydrodynamic Simulations of the Solar Atmosphere

Solar physics is entring a new, vibrant era starting in 2020 with the commissioning of the 4-m Daniel K. Inouye Solar Telescope (DKIST) and the ESA Solar Orbiter space mission. For the conception of observations and the interpretation of the collected data, three-dimensional radiation magnetohydrodynamic numerical simulations are of indispensable aid. Here, we propose the post-processing of own existing, and the production of new simulation data for carrying out research on four different topics of solar physics: two closely related to future observations with DKIST, the rest related to ongoing observational programs at IRSOL. Beyond that, we propose the further development of our simulation tools and computational methods with regard to supercomputing and the future era of exa-scale computing. We also plan for universal access of our simulation data including tools for the computation of derived physical quantities. The proposed research is relevant for various fields of solar and stellar physics, for users of the CO5BOLD simulation tool, as well as for computational astrophysics in general. We also plan to conclude SNF project 200021_159206/1 on radiative transfer in discontinuous media within the proposed program. The main part of the project shall be the subject of a PhD-thesis and a postdoctoral work. The PhD student is foreseen to be inscribed under the supervision of Prof. Rolf Krause at the Institute of Computational Science of the Università della Svizzera italiana, of which IRSOL is an associate.
