Abstract:This paper reviews the numerical simulations of radiative jets with concrete predictions of the emitted radiation, which can be compared directly with observations of individual HH objects. The only models that have been developed to this point are the “internal working surface model” (in which the structures along HH jets are interpreted as working surfaces resulting from a time-variability in the ejection) or the “Kelvin-Helmholtz instability model” (in which the HH knots are associated with shocks resulting from K-H instabilities in the jet beam/environment boundary). The predictions of intensity maps, line ratios, line profiles and proper motions are discussed.
