Jet collimation by combining axisward motion and cooling Academic Article uri icon


  • A simple scheme is proposed for hydrodynamical collimation of astrophysical outflows into jets: Matter launched from a base with a ringlike topology can undergo a sticky collision at the axis and remain collimated. No ambient medium is required, though a significant fraction of the outflow could avoid strong collimation.
