Abstract:
The Sun serves as the local physics laboratory for studying
the suprathermal activity phenomena of
stars. Scrutiny of the Sun has led to the discovery of a host of previously
unknown physical effects, largely within the classical physics of Newton and
Maxwell, but including quantum mechanics and lepton physics as well.

Abstract:
Here, we argue that, despite all-new findings of phenomena with very large
Lorentz factors, the importance of the magnetodynamic process
accelerating and collimating AGN jets should not be affected because
there exists evidence in the features of the
jets and tails at large distances
indicating that the wiggles of the jet structure are
likely to be due to a magnetic, helical kink instability.
These systematic features require too much energy and coherence of
the driving process to be produced locally and are most naturally produced
by a magnetic effect coming from the powerful central engine.
This indicates that the
major effect producing the jets, and the lobes with hotspots at the tips
of the jets, is likely to be the Poynting flux carried by
torsional Alfven wave trains plus the
re-accelerated high-energy particles in them. The very large Lorentz-factor
phenomena should not hinder the transfer of these magnetic effects
and are likely to be byproducts of the basic
magnetodynamic process, and not the reverse.
