Abstract
A cylindrical magneto-hydrodynamical model for the transverse structures of the nonrelativisitic jets observed from young stars is proposed. The importance of the temperature terms in the equations describing one-dimensional cylindrical flows is discussed. It is shown that taking into account heating at an oblique shock at the base of the jet makes it possible to obtain physical parameters of the jet that are in good agreement with observations. In particular, the jet can be confined by an external magnetic field of the order of 10−6 G at a distance of 100 AU from the rotational axis.
