Here is a cartoon drawing attention to the perceived similarities between a
Tokamak and a solar flare, with reference to the short-lived but influential
Alfven-Carlqvist model.
An additional cartoon in the paper rotates the torus by 90°ree; and
allows its current to connect seamlessly across the photosphere.
This kind of circuit-theory approach should be pursued, the Archivist feels,
but notes two blithe assumptions here.
First, why should Te = Ti?
Second, how can a current close in the photosphere or anywhere in the
solar atmosphere, rather than in the deep interior?
That's where the stresses exist.
The cartoon itself shows a horizontal Tokamak, which pretends to solve
the problem of how to link the current through the photosphere.
There is no observational evidence for complete toroids in the corona.
