Research Interests

My main area of research is the modeling of stellar and planetary atmospheres using computer simulations with our Phoenix code. This is a large scale supercomputing application, my group regularily uses large parallel supercomputers that can be found in the top 10 of the world's fastest supercomputers.

Related topics are...

• 3D radiative transfer algorithms and their implementation.
• continue the development & verification of PHOENIX/3D.
• The atmospheres and spectra of novae, M dwarfs & giants, Brown Dwarfs, L/T dwarfs, T Tauri's, SNe, basically everything that radiates.
• Irradiation of planets and secondaries of CVs
• Analyses of Nova, M/L/T dwarf & giant, Brown Dwarf, T Tauri, and SN spectra.
• The detailed physics of nova spectra, in particular line blanketing and NLTE effects.
• Numerical methods for NLTE and radiative transfer calculations.
• Line formation, blending and blanketing in (relativistically) expanding atmospheres.
• Radiative transfer in relativistically expanding, spherical atmospheres.
• Detailed NLTE calculations for extremely large model atoms.
• Effective numerical methods to treat 100's of millions spectral lines individually with detailed profiles.
• Molecular line opacities.
• Line broadening in very cool stars.
• Finishing the next versions of the M/L/T-O dwarf and nova model grids.
• Models for Stellar Winds
• Keeping PHOENIX/1D and PHOENIX/3D alive and happy (currently at version 16).
