Stellar and Solar Physics

Our team aims at providing answers to some key questions of solar and stellar physics, such as the heating process of the corona or the structure of solar and stellar interiors. The magnetic field playing a fundamental role in structuring the atmospheres of solar-type stars, it becomes possible to understand the coupling between the internal generation of magnetic field and its external signatures. The two major research topics are thus the dynamic and internal structure of the Sun and stars, and diagnostic and heating of the outer layers.

The first images from ESA’s new Sun-observing spacecraft Solar Orbiter have just been released. Solar Orbiter, launched on 10 February, completed its commissioning phase in mid-June and performed its first close approach to the Sun. Shortly thereafter, the European and US science teams behind the mission’s 10 instruments were able to test the entire instrument suite in concert for the first time.
