Sunspots play an important role in understanding the dynamical nature of the solar magnetic field. Although their surface appearance has been observed for over four centuries, little is known about the subsurface structure. Sunspots are known to strongly influence solar acoustic modes and there is a...

With increasing aperture size of telescopes, the maximum possible theoretical resolution of observations increases as well. This leads to the possibility of observing structures and phenomena, which have not been discovered yet. With the help of the solar telescope GREGOR, these observations can be...

Standard algorithms for tracking small scale magnetic features suffer
from ambiguities due to the intrinsic complexity of the feature
interactions which are driven by photospheric convective motions.

In his Ph.D. work, Andrei Gorobets will work on an alternative concept
for tracking the evolution...
