Abstract:
During star formation, there is a phase when the emission of jets is likely to occur. Many efforts were done lately, with the increase in available computational power, towards the numerical modeling of these flows. Magnetic field seems to be a key ingredient not only in jet formation, but also in large-scale propagation, affecting the radiative emission properties of the jet plasma. Pre-ionization models of the jet material are important for the morphology and intensity of the knots os enhanced line emission visible in stellar jets. We will present the results of such radiative MHD simulations, including a complex ionization network and cooling function, and our approach to "synthetic observations" of stellar jets.
