Scientific paper

A vortical mechanism for the collimation and acceleration of astrophysical jets is proposed on the basis of exact solutions of the hydrodynamic equations in a homogeneous gravitational field taking viscosity into account. Velocity profiles in the form of a jet structure with a uniformly rotating trunk whose pressure decreases in time, and longitudinal and converging radial flows of matter, are examined. Because of the radial flow, the angular velocity of the trunk and the velocity of the longitudinal flow of matter can accelerate exponentially or in the manner of an “explosive” instability. Flows of this type have low energy dissipation and can serve as unique channels for the acceleration and collimation of jet eruptions from young stars, as well as from active galactic nuclei and quasars.
