3D Spectral Radiative Transfer and Perspectives for Spectroscopic Diagnostics

Abstract

We present the features of the three-dimensional (3D) radiative transfer code IRIS, which synthesizes spectra emitted from hydrodynamics structures. We discuss our first application of IRIS to the analysis of a laboratory radiative shock. We demonstrate, with the help of the radiation hydrodynamics (RHD) code HERACLES, the existence of a radiative precursor. We validate the gray approximated model M1 used by HERACLES. We show a couple of synthesized X-UV spectra of such a shock. We finally open up our discussion to the future possibilities of spectroscopic diagnostics of accreting streams onto the surface of Classical T Tauri stars (CTTSs).
