Radiative bow shock models of Herbig-Haro objects

摘要: The bow-shock models of HH objects presently constructed from a collection 43 radiative-planar-shock are used to predict the line ratios and profiles expected objects. It is found that radiating-bow-shock model formed around 'bullet' dense gas plowing into ambient medium accounts for existing observations sufficiently well constitute unifying model. For particular orientations, double-peaked predicted in spatially unresolved spectra. A simple analytic formula presented can be estimate shock velocity orientation single high-resolution observation low-excitation line. 63 references.
