Good Grief, Who wrote this description? They haven't a clue what's actually going on here.
This is the same structural event as surrounds Supernova 1987a. Just compare them.
The structures weren't 'ejected' from the central stellar object, they were formed from the ISM (the Interstellar Medium) as aggregated by Marklund Convection forces and the magnetic fields present, as well as any electric field.
Someone in Mainstream Astrophysics needs to take a graduate level course in Electrical Engineering before they start trying to describe objects like this.

This is a Mainstream Astrophysics forum. It is not Graduate Electrical Engineering forum, nor is it the place to advance theories about Plasma Cosmology or Electric Universe. There may be other places to discuss those topics, but this isn't it. Read the Rules before posting.

They shine because they remain embedded in the galactic power grid
A model for filamentary plasma structures associated with force-free magnetic fields is presented. A homogeneous electric field parallel to the symmetry axis of the magnetic field is assumed. Under the influence of these fields, the plasma will drift radially inwards with a velocity resulting in an accumulation of plasma in the central region. Recombination losses are assumed to keep the central plasma density at a finite value, and the recombined plasma i.e. the neutrals to diffuse radially outwards. Plasma density and some neutral gas density distributions for a steady state situation are calculated for various cases. http://adsabs.harvard.edu/abs/1978ssmf.rept.....M

There's no need to bring further attention to the previous bad post (which also violates the forum rules). The paper you reference is long since discredited. All of this plasma cosmology stuff has been relegated to the junk heap of old science; current practitioners are, for the most part, pseudoscientists, which is why plasma cosmology is generally off-limits in this forum.

Thank for info.

[I must say, Neufer, before I’m dead and gone, that your exceptionally wonderful and talented efforts here are vastly appreciated !!! I admire your abilities to post text in color, include photos and data charts etc, to organize it in a logical and instructive way, and all your ingenious connecting thoughts, humor, and inspirations researched and supported !!! (well, flattery will get me nowhere, but credit where credit is due !!!) Now, back to my heresy below !]

To my way of thinking, the Milky Way’s ‘double bubbles’ are the expression of the ‘polar energy fields’ present, which are exciting the matter in their purview to emit gamma and x-ray radiations, as well as microwave and infrared etc.. As in the central region of the Crab Nebula there is synchrotron radiation due to the intense ‘fields’ present there, in our galaxy there are also ‘radiations’ due to its ‘fields’ as well.

Our galaxy isn’t as powerful or as long-term developed as galaxies with ‘jets’ at their poles, yet, and maybe it never will have jets. Jets would depend on the level of energetic activity necessary at the galactic core, and the strength of the magnetic field that develops around any ‘charged matter’ that is being expelled at the poles.

The magnetic field arises as the charged particles move, and works to keep them collimated in a tight stream, by its orthogonal circular shaped structure surrounding the ‘particle stream’s’ length. The arising magnetic field acts like a ‘pipe’ constraining the flow inside itself from expanding outwards, except for in the forward pipeline direction. [*see M87’s jet for illustration. http://antwrp.gsfc.nasa.gov/apod/ap041211.html ]

The motion of groups of electrically charged particles is by definition ‘an electric current’, and subsequently Maxwell’s (and Heaviside’s) equations come into play. Likewise, magnetic fields come into play, as well as synchrotron radiation effects when the energies and fields become high and strong enough.

Our galaxy, and most all galaxies, show some level of this ‘energy and field’ activity at their poles and their equators. Our galaxy is just beginning to show activity at its polar regions, and the gamma ray energies indicate we are on our way to ‘bigger’ things ! Careful analysis of the magnetic field activity closer-in to the galactic core’s polar regions (a difficult area to view admittedly) will yield 26,000 year old information about what’s happening there now !

And in review:

The Electric Field has Three causative sources:

1 - the charge density
2 - the time derivative of the charge density
3 - the time derivative of the electric current density

The Magnetic Field has Two causative sources:

1 - the electric current density
2 - the time derivative of the electric current density

The prominent presence of [derivative J over derivative t] and [the derivative of J over derivative t], in the formulas, indicate that the time derivative of the electric current density is the primary causative agent of both electric and magnetic fields, with the charge density and its time derivative being of equal prime importance in electric fields.

Thus: electric and magnetic fields are always simultaneously created by the same
time-variable electric current with its charge density also modulating the intensity of the electric field.

“There is a widespread belief that time-variable electric and magnetic fields can cause each other, but an analysis of Maxwell’s equations does not support this belief. It is true that whenever there exists a time-variable electric field there also exists a time-variable magnetic field, but neither Maxwell’s equations (and also as reformulated by Oliver Heaviside) nor their solutions indicate an existence of causal links between electric and magnetic fields.

Therefore: an electromagnetic field is a dual entity, always having an electric and a magnetic component simultaneously created by their common source:
time-variable electric charges and currents.”

Re: APOD: The Necklace Nebula (2010 Nov 03)

This thread has gathered some posts that are outside the subject matter of the Starship Asterisk. I would like to remind posters, whether registered or guest, that this is a mainstream science board. Please note the following, which is Rule 15 in the Handbook:

Alternative Theories and Conspiracy Theories
This board concentrates on the mainstream or consensus view of cosmology. Alternative theories and conspiracy theories are not discussed here. We may decide to allow limited discussion of these at some later date. For now, however, we ask that you take these discussions to other boards that allow such discussions, such as The BAUT Forum.

Thanks for your cooperation.

What is owlice reference in the following submission ?

A number of posts had been made espousing alternate theories of cosmology (as in, not generally accepted by scientists in the field), which are not allowed here. They were (re)moved, and my post is an attempt to head off any other such posts.

This is a mainstream forum. Alternative theories (Electric Universe/Plasma Cosmology) are not discussed here. Read the rules before posting. Further violations may result in a permanent ban of IPs.
