Abstract

Protostellar jets from intermediate- and high-mass protostars provide an excellent opportunity to understand the mechanisms responsible for intermediate- and high-mass star formation. A crucial question is if they are scaled-up versions of their low-mass counterparts. We present a detailed study of the IRAS 20126 + 4104 molecular jet, driven by a 104 L⊙ protostar. The kinematical and physical properties of the jet have been obtained by means of NIR narrow-band imaging, high resolution and low resolution IR spectroscopy. We then compare our findings with those of other high- and low-mass protostellar jets available in the literature, proposing an evolutionary scenario from low- to high-mass jets.
