The field of asteroseismology is currently undergoing a major revolution due to the highprecision
photometry data of the NASA Kepler space telescope. For the first time long, uninterrupted,
high cadence, photometric time series of a large number of stars is available. These
data enable asteroseismology...

Solar activity varies with a period of roughly eleven years. This cycle has been discovered in the variation of the number of visible sunspots. The origin of those spots lays in the magnetic field and the dynamo process that is creating it. The study of sunspots not only tells us about the...

Direct detection of gravitational waves (GWs) would not only provide a tool to test and validate general relativity, it would also most likely open the field of GW astronomy and cosmology, yielding unprecedented information about astrophysical systems and the (very early) universe that cannot be...

This diploma thesis investigates the Paschen-Back effect in the 0 − 0 band of the A6Σ+ − X6Σ+ system of the CrH molecule and demonstrates a possible astrophysical application.
The theoretical investigation of the molecule starts with the diagonalization of the Hamil- tonian matrix represented in...

The Sun’s radiation, which arises on the convective star surface, is the major source of our knowledge about it’s structure. Realistic numerical simulations of magnetohydrodynamical convection together with radiation transfer are the keys to understanding the information encoded in the radiation. In...
