Abstract:The link between gasdynamical models and observations is crucial. The general progress in numerical simulations must be accompanied by predictions for observable quantities, which not only allow to test the models or parts of them against observations but which also improve the understanding of observational data. In this paper we focus on predictions for observations, for three examples of 3D hydrodynamical simulations of binary star systems, and the techniques required for their derivation. The examples include synthetic, optically thin Doppler broadened line profiles for colliding wind symbiotic binaries, the UV light curve of an accretion model for the symbiotic binary RW Hya, and the X-ray light curve of the WR+O binary γ Velorum. The main purpose is to emphasize the importance of such studies and to illustrate the capabilities of the emploied tools. The tools are all contained in the A-MAZE code package we have developed and are publicly available.
