Completely wrong.
Yes, pretty much everything you have said is completely wrong.
Your own source clearly indicates the atmosphere is the source of the ions, which start out at low energies, which also means there is no need for a magical second sun.
Even the section you quoted:
"all this low-energy plasma flowing out"
Not high energy plasma from a sun.
And no, it doesn't mean I can't read a scientific paper. What you provided wasn't even a scientific paper, it was a press release.
But far more importantly, you are still blatantly lying about what it is saying.
Yes, it says some are accelerated to reach into the tail of the magnetosphere.
Notice how that isn't saying they have reached the massive energies associated with the auroras?
Here is the part you are ignoring:
"When it flows into the plasma sheet, it is dramatically energized - from about 5 eV to 5,000 eV."
"they go into the plasma sheet, and are energized at least a thousandfold.""
