The cartoon

Sorry - still more CSHKP, but there may have been new wrinkles here in this early and influential cartoon. It does miss the dimple at the stagnation point of the reconnection outflow, a minor feature discovered later in the simulations but probably never observed in any direct sense.

      This is a nice symmetric and minimalist version of CSHKP, and the point P is mercifully not described in detail. Note the wavy lines marked "fast particles" - these are probably not energetically dominant particles as in the Elliot cartoon, but more likely kinetic Alfvén waves. The cartoon is a bit fishy in a at least one way: why should the "HOT" part be cusp-shaped, since the energy comes from the shocks?? In this sort of model the heating results from dipolarization and the operation of the slow shocks, so the rounded field lines should be hotter than the pointy ones.
