I wanted to gel with the thunderbolts forum peeps to check what the general current view is on star birth.
Wal has been pointing things out in recent space news episodes and there are confusing (different) ideas on what exactly happens during star birth.
I propose that in a z-pinch, or star forming filament, only 1 star is born (per pinch). But when astronomers observe (as Wal also pointed out) a birth they see usually 2 stars, an archetypical example is R Aquarii*, where mainstream proposes a red giant and white dwarf, the white dwarf feeding on the red giant. I have no idea why/how they arrive at such a concept, that view looks nothing like the actual observation.
in EU the pinch is 2 umbrella's (as Don Scott said), the classic hour glass shape, all star births have this shape (every planetay nebula so far observed is probably a star birth), the larger structure is the star forming filament, the pinch is embedded in this larger filament. With EU we see 2 plasmoids swirling around each other, the magnetic pinch (imho) should produce 1 star when the pinch subsides, but Wal says that 2 stars could form, or 1 star and 1 planet, i think Wal also said , 1 star (or more) in parts of the filament and along the filament also planets if not enough material for a star. Any other ideas?

And also maybe we need better and more descriptions of the z-pinch process, from start to finisch, there are certain energetic phases and quiet phases.. EU should build a model of a complete z-pinch event, and how can we test this in the laboratory, i think an experiment setup that produces a pinch in an dusty/gassy chamber should be possible. Put some high speed camera's to witness the pinch and we can have the complete picture in seconds...
