Hoyle, F. and N. C. Wickramasinghe, A note on the origin of the Sun's polar field, MNRAS, 123, 51 (1961) (ADS)
(click on the image for a larger version)
The paper presenting this cartoon, which described the origin of the global
solar polar field, attests to
Fred Hoyle's [1]
continued interest in solar magnetism
(see also the iconic Gold-Hoyle
flare cartoon). They were concerned with the time scales and thanked
Peter Sweet [2]
for help with this issue.
Though the shorthand idea of magnetic reconnection was already available,
the presentation here is in terms of Ohmic dissipation.
Possibly this distinction still remains undefined.
The fact that this cartoon looks
just like any of many cartoons evoking reconnection explicitly probably should make
us realize that neither simplifying approximation adequately relates the
global structure to the microphysics. This still perplexes our pundits.
Note that this cartoon describes a "typical coronal streamer", ie the
bipolar kind associated with the heliospheric current sheet.
Not long after this, the
"pseudo-streamers" also
appeared.
