Objectif Young stars eject spectacular displays of jets and bullets of gas. These outflows are believed to be crucial to the successful birth of a star. We propose to determine the nature and implications of these outflows by analysing their physical parameters and spatial structure. For this, we need to employ new spectroscopic instruments in conjunction with our large telescopes. The major aims of the project are as follows:(1) Observation. To apply the powerful capabilities of modern 3D spectroscopy to the study of out flowing phenomena from pre-main sequence stars. To obtain good quality data for selected nebulous objects in star forming regions through the detailed spectro-imaging and spectrophotometric study at the 2.6m and 6m telescopes of Byurakan Observatory and Special Astrophysical Observatory (SAO);(2) Analysis. To construct new models, especially for such phenomena as helical jets and helical structures in nebulae;(3) Interpretation.To explore(1) the hidden inflow-outflow connection at the heart of a young stellar system;(2) the evolution of the system's spin by searching for the signs of rotation and precession;(3) the dynamical feedback into the environment and;(4) the physics of shock waves and magnetic fields in the interstellar medium;(4) Advancement. To improve the observational capabilities of the 2.6m and 6m telescopes by purchasing and installation of optical elements (high-resolution grism, filters, gratings) specific to the above goals. Especially should be noted that this will support the development of new technique of multi-pupil spectroscopy of high spectral resolution;(5) Collaboration. To strengthen further the basis for the tight collaboration and cooperation between the teams involved in the project. Especially the intended close cooperation between observers and theoreticians should be noted.
