(polar jet, astrophysical jet)
(stream of matter from an astronomical body)
A jet (or polar jet) is a stream of matter (e.g., plasma)
sent with apparent force from an astronomical body
such as a black hole.
Their mechanism is not agreed upon,
but magnetism (e.g., magnetic field under rotation)
is presumed to be a component.
Bodies with accretion disks such as protostars,
neutron stars often show jets
as well as active galaxies often show jets
sent in one or both directions along the axis of rotation,
polar jets or disk wind.
A relativistic jet is one in which matter is
emitted at speeds approaching light speed.
For active galaxies, they are termed AGN jets or galactic jets.
In the case of stars (stellar jets), high stellar rotation
makes them oblate, and the surface at the poles is nearer the core,
thus hotter, contributing to jet formation.
The word jet is also sometimes short for jet stream,
a type of wind on a planet (see zonal flow),
