The general aim of this project is the investigation of astrophysical processes through the use of stateoftheart numerical codes on massively parallel computers. More specifically, the research in many astrophysical fields requires an understanding of gas dynamical, magnetic, radiative transfer and gravitational phenomena not accessible to purely theoretical analysis. In the framework of this project calculation aimed at understanding the multidimensional structure and evolution of magnetic fields in stellar atmospheres and interiors are carried out, including magnetohydrodynamical aspects, radiative transfer and spectral line polarization. Special emphasis is placed on the comparison of the theoretical/numerical results with observational data.
- Small magnetic loops are observed to appear in the interior of individual granules in the quiet Sun. Using 3D numerical the mechanisms that produce this emergence is discovered. The results have been published in ApJ Letter 859, id. L26 and led by Prof Fernando Moreno-Insertis.
- In an international collaboration, almost 200 solar prominence oscillations events have been catalogued. This is the first statistically significant study of these phenomena done that also includes large-amplitude oscillations. This work has been led by Dr Manuel Luna and published in ApJ Supplement Series, 236, id. 35.
