Entrainment in Herbig-Haro objects

This paper first reviews the literature of entrainment of molecular material into HH jets. The available models can, in principle, reproduce the H2 emission of a number of HH objects. However, there are some HH jets with aligned knots which show basically identical structures in the H 2 and atomic/i...
