Consistent Radiative Transfer Models including Time Dependent Energy Deposition for Type Ia Supernovae
P. Hultzsch, D. Sauer, A. W. A. Pauldrach +1
Many aspects of the explosion mechanism of Type Ia supernovae (SN Ia) still remain unclear -- causing uncertainties in the derived cosmological parameters. Realistic models of the…

Radiation driven atmospheres of O-type stars: constraints on the mass-luminosity relation of central stars of planetary nebulae
A. W. A. Pauldrach, T. L. Hoffmann, R. H. Méndez
Recent advances in the modelling of stellar winds driven by radiation pressure make it possible to fit many wind-sensitive features in the UV spectra of hot stars, opening the way…

Spectra of High Redshift Galaxies using a Cluster as a Gravitational Telescope
D. Mehlert, S. Seitz, R. P. Saglia +7
Using the Focal Reducer Spectrograph (FORS) at the Very Large Telescope (VLT) during the FORS commissioning time in December 1998 we took long slit spectra of the gravitational arc…
