Cartoon showing how stellar radio emission may develop in a magnetospheric analog.
One can imagine developments of this model leading to flaring.
It actually resembles the global solar field as well, of course,
but note the differences: the "dead zone" contains both thermal and
relativistic plasma, whereas the "wind zone" contains thermal plasma as well.
The toroidally trapped relativistic plasma produces quiescent stellar gyrosunchrotron
emission.
From a solar perspective, it seems improbable that the
wind zone would contribute much soft X-ray emission.
