TL;DR

This paper presents new ideal magnetohydrodynamics solutions that replicate the internal structure of plasma jets from young stars, as observed in laboratory plasma focus experiments.

Contribution

It introduces a novel class of axisymmetric stationary flow solutions that model the internal structure of astrophysical jets in laboratory simulations.

Findings

New solutions for ideal MHD equations match observed jet structures.

Laboratory plasma focus experiments effectively simulate astrophysical jet internal regions.

The solutions provide insights into the active regions of stellar jets.

Abstract

The laboratory simulations of jets from young stars that have been carried out for many years at plasma focus facilities allow the internal structure of the active regions emerging during the interaction of the jet with the surrounding plasma to be studied in detail. We have found a new wide class of solutions for the equations of ideal magnetohydrodynamics describing the closed axisymmetric stationary flows that are apparently realized in the active regions. Such flows are shown to well reproduce the internal structure of the plasma structures observed in laboratory simulations of astrophysical jets.
