Spectroscopy in the J band (even at low resolutions of R<~103) is a mode commonly available in most near-IR spectrographs but is rarely exploited in star formation studies. We show how it is a crucial tool to tracing the physics (temperature, density, excitation mechanisms) of protostellar jets and Herbig-Haro (HH) objects. In this framework the spectrum of HH 43 is revisited as both a clear demonstration of our statement and a case of slow J-type shock excitation. Based on observations collected at the European Southern Observatory, Chile.
