Dynamical models of radiative shocks. III - Spectra
Abstract
The authors have investigated the spectral characteristics of steady and unsteady radiative shock models in the context of Supernova Remnants (SNRs). By means of detailed, multi-level radiative transfer calculations, they have generated emission and absorption line profiles for selected shock models. Geometrical effects are simulated by forming the plane models into a thin spherical shell, which is then observed along different lines-of-sight. The authors show that the nature of unsteady shocks can best be studied through observations of absorption and emission line profiles along lines-of-sight near to the centre of the SNR. Also, they show why emission maps in the light of optically thick transitions should not exhibit the bright filaments associated with optically thin lines.
