Laboratory and Numerical Modeling of the Structure of Shock Waves of Jets from Young Stars

Abstract

The use of Z-pinch facilities makes it possible to carry out well-controlled and diagnosable laboratory experiments to study laboratory jets having scaling parameters close to those of jets from young stars. It was found that a low-concentration region is formed after the first supersonic ejection, allowing subsequent ejections to propagate collimated. An exact solution of the generalized Grad–Shafranov equation for axisymmetric plasma flows was also obtained, and the interaction of the plasma ejection with the gas was numerically modeled, which agrees well with the experimental data.
