H. Abstract High-resolution long-slit spectra of DG Tau and the associated mass outflow are presented. The detailed spatiokinematic structure of the outflow regions in the immediate vicinity of the central star and the variations of the electron density and excitation have been deduced on a subarcsecond scale from the analysis of the spatially resolved forbidden lines. Following the model of Kwan and Tademaru (1988), we suggest that two separate gas components in the outflow, a rather compact low-speed component and a more extended highspeed component, contribute to the observed line emission.
