The interaction between an isotropic stellar wind and a stratified environment can lead to the formation of de Laval nozzles (in the adiabatic case) or to the formation of an elongated cavity surrounded by a dense cold shell of shocked gas (in the limit of short cooling distances; i.e., in the highly nonadiabatic case). A preliminary exploration of the intermediate regime between the adiabatic and the highly nonadiabatic regimes yields very interesting results. While for cooling distances larger than about 5 times the environmental scale height the flow resembles the adiabatic de Laval nozzle, for shorter cooling distances the flow is considerably different, leading to the formation of very narrow well collimated cold jets. A preliminary comparison between observations of the HH 1/2 source and radio free-free spectra computed from these models gives very encouraging results.
