In the "Solar and Stellar Interiors" department, Laurent Gizon, Jesper Schou, Aaron Birch, Robert Cameron 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.
Studies of the Sun or other stars rely on indirect observations, i.e. we can only observe effects of an unknown quantity. This group works on the corresponding inverse problem to reconstruct the unknown cause from the observed effect, e.g. the reconstruction of convection fields from measurements of oscillations of the solar surface.
