Annotation:

Beltrami disk-jet model (Shatashvili & Yoshida 2011) is used to derive hydrodynamic models of the disk-jet structures in young stellar objects. The role of magnetic field and two-fluid effects is studied for the formation of disk-jet structure. The control parameter ranges are analyzed and illustrative figures are constructed. Specific results include: - Generalized equations in the two-fluid model are derived; - Equations in the two-fluid model are derived for specific YSO phenomenology; - The two-zoned model for the density is used to construct the self-similar solution; - Conditions for the existence of collimated jets are found. The effect of magnetic field in the jet collimation is studied.
