    • Indirect imaging of AM Herculis-stars 

      Staude, Andreas (Univ. Berlin, 2005)
      AM Herculis stars (or 'polars') are close binaries consisting of a white dwarf with a strong magnetic field and a main sequence star (the 'secondary') which is losing mass to the white dwarf. The magnetic field channels ...
    • Modeling atmospheres of classical novae in X-rays with PHOENIX 

      Petz, Alexander (Univ. Hamburg, 2005)
      PHOENIX has been used to calculate model atmospheres of classical novae in the X-ray spectral range. The models account for an expanding, one-dimensional spherically symmetric medium in full non-local thermodynamic ...
