Non-LTE models for synthetic spectra of type Ia supernovae. IV. A modified Feautrier scheme for opacity-sampled pseudo-continua at high expansion velocities and application to synthetic SN Ia spectra
T. L. Hoffmann, D. N. Sauer, A. W. A. Pauldrach +1
Context. Type Ia supernovae (SN Ia) have become an invaluable cosmological tool as their exceptional brightness makes them observable even at very large distances (up to redshifts…
Radiation-driven winds of hot luminous stars. XVIII. The reliability of stellar and wind parameter determinations from spectral analysis of selected central stars of planetary nebulae and the possibility of single-star SN Ia progenitors
C. B. Kaschinski, A. W. A. Pauldrach, T. L. Hoffmann
Context. The uncertainty in the degree to which radiation-driven winds of hot stars might be affected by small inhomogeneities in the density leads to a corresponding uncertainty i…
Non-LTE models for synthetic spectra of type Ia supernovae. III. An accelerated lambda iteration procedure for the mutual interaction of strong spectral lines in SN Ia models with and without energy deposition
A. W. A. Pauldrach, T. L. Hoffmann, P. J. N. Hultzsch
Context. Spectroscopic analyses to interpret the spectra of the brightest supernovae from the UV to the near-IR provide a powerful tool with great astrophysical potential for the d…
