Scientific paper

Three new young objects have been found when carrying out a survey of IRAS sources with infrared colors like planetary nebulae, via low resolution spectroscopy. IRAS 14592 - 6311 and IRAS 07173 - 1733 are bright cometary nebulae, showing metal line emission very similar to V1331 Cyg, which is the prototype of a certain number of T-Tauri stars. They present strong P-Cygni profiles and some other peculiar characteristics. IRAS 07173 - 1733 is located on the edge of the dark cloud KHAV 201. In the case of IRAS 05506 + 2414, it presents a bipolar structure with Herbig-Haro emission characteristics in one of the lobes, produced by shocked gas.
