Astrophysical jet
Stream of ionized matter flowing away from a rotating astronomical object
Astrophysical jet
An astrophysical jet is an astronomical phenomenon where ionised matter is expelled at high velocity from an astronomical object, in a pair of narrow streams in opposite directions, aligned with the object's axis of rotation. When the matter in these streams is flowing at close to the speed of light, the jet is referred to as a relativistic jet, as it demonstrates phenomena predicted by special relativity. Astrophysical jets are associated with many types of high-energy astronomical sources, such as black holes, neutron stars and pulsars. Their causes are not yet fully understood, but they are believed to arise from dynamic interactions within accretion disks. One explanation is that as an accretion disk spins, it generates a rotating, tangled magnetic field which concentrates material from the disk into the jets and then drives it away from the central object. Jets may also be influenced by a general relativity effect known as frame-dragging. Most of the largest and most active jets are...
