Why do some celestial objects develop jets ?

it is amazing that jets were discovered at a so large diversity of celestial bodies,
from the supermassive black holes over tiny neutron stars and now also at only 24 Jupitermasses brown dwarf 2MASS1207-3932.

It is still more amazing that no satisfying explanation was found for the origin of jets. The general reference to magnetic fields lets arise the question:
why then not also with our sun or comparable stars?
Magnetic fields play also for our sun and comparable stars a considerable role, why do they not have jets too?
(would look certainly beautiful )
