- Astrophysical_jet abstract "An astrophysical jet (hereafter 'jet') is a phenomenon often seen in astronomy, where streams of matter are emitted along the axis of rotation of a compact object. While it is still the subject of ongoing research to understand how jets are formed and powered, the two most often proposed origins are dynamic interactions within the accretion disk or a process from the central object (such as a black hole). When matter is emitted at speeds approaching the speed of light, these jets are called relativistic jets, because the effects of special relativity become important. The largest jets are those from black holes in active galaxies such as quasars and radio galaxies. Other systems which often contain jets include cataclysmic variable stars, X-ray binaries and T Tauri stars. Herbig–Haro objects are caused by the interaction of jets with the interstellar medium. Bipolar outflows or jets may also be associated with protostars (young, forming stars), or with evolved post-AGB stars (often in the form of bipolar nebulae).Accretion disks around many stellar objects are able to produce jets, although those from super massive black holes are the fastest and most active. This is because the speed of the jet is around the same speed as the escape velocity of the central object. This makes the speed of a jet from an accreting black hole near the speed of light, while protostellar jets are much slower. While it is not known exactly how accretion disks manage to produce jets, they are thought to generate tangled magnetic fields that cause the jets to collimate. The hydrodynamics of a de Laval nozzle may also give a hint to the mechanisms involved.One of the best ways of exploring how jets are produced is to determine the composition of the jets at a radius where they can be directly observed. For example, it has been suggested if a jet originates from the accretion disk, its plasma is likely to have ion-electron composition, whereas if it originates from the black hole or neutron star it will likely be positron-electron in nature. Also, the plasma emits various forms of radiation such as X-rays and radio waves, which aid diagnosis.".
