Abstract
We review the first results of a 45-190 microns spectroscopic study of a sample of Class 0,~~Class I, ~~Class II (Herbig Ae/Be) and Herbig-Haro objects. In the observed Class 0, Class I and HH objects J shocks can account for the [OI] observed intensity, while for Ae/Be stars the [OI] emission is mainly due to the presence of photodissociation region. For some Class 0 and Class I sources, high-J CO transitions are the dominant FIR coolants, indicating the additional presence of C shocks. In these sources the H2O cooling is significantly less than that predicted by models. Finally, evidence is seen for [OI] 63 microns self-absorption in all the Class I and the Class II objects of the sample.
