Inversion codes are used to aid the detailed interpretation of solar spectro-polarimetric data. This computer code attempts to find the atmospheric structure that produced an observed spectrum by minimizing the difference between the observed spectrum and a Stokes spectrum.
In the "Solar and Stellar Interiors" department, Laurent Gizon, Tom Duvall, Jesper Schou, Aaron Birch, Robert Cameron, Friedrich Kupka and others offer PhD projects in solar physics and astrophysics. Helioseismology and asteroseismology are used as important tools to study the oscillating Sun and stars.
Helioseismology and asteroseismology use the oscillations of the Sun and stars to probe their interior structure and dynamics. These tools allow us to test and refine the theory of stellar structure and evolution, thereby bringing us closer to understanding solar and stellar magnetism.
