About Me

I have studied Physics and Astronomy at the University of Hamburg (Germany). My Master thesis I have done at the INTEGRAL Science Data Scenter in Geneva (Switzerland).Next I moved on to the University of Utrecht (Netherlands) where I optained my PhD. Now I am based at the University of Vienna, working as a University Assistant (Postdoc).

Massive Stars

With masses of ~5-100 times the mass of the sun, massive stars live a very rapid and influencial life. As cosmic engines they synthesis the elements we are all made of and distribute these in the universe through strong stellar winds during their life and in spectacular supernova explosions in their dead.

During their Hydrogen burning lifetime, massive stars show very different amount of Nitrogen and Helium on their surface, but often much larger amounts than found in the sun. These elements are synthesized in their cores, but unclear how they are transported to the surface while the star is still on the main sequence. Rotation, indicated by high surface velocities of most massive stars seems to be a key, but many questions remain. I am studying this problem using stellar evolution models including the theory of rotational mixing.

3D simulations of protoplanetary disks

Models of protoplanetary disks are usually calculated in 1+1D approximations, meaning the disc is approximated as 1D slices. While much progress has been achieved with these kind of models, real disks are 3D. Planet formation is suspected to cause non-systemic structures in discs, which can only be modeled in 3D.

Based on the 3D radiative transfer environment PHOENIX/3D, we are developing a new code to simulate protoplanetary discs in 3D and study the effects planetformation has on them.
