Although bipolar jets are seen emerging from a wide variety of astrophysical systems, the issue their formation and morphology beyond launching is still under study. Our scaled laboratory experiments, representative young stellar object outflows, reveal that stable narrow collimation entire flow can result presence poloidal magnetic field whose strength consistent with observations. The plasma becomes focused an interior cavity. This gives rise to standing conical shock which jet emerges. Following simulations process at full scale, we conclude it also explain recently discovered x-ray emission features observed in low-density regions base protostellar jets, such as well-studied HH 154.
