This is a modern view of the hoary
"thick-target model",
now with an effort to understand the electrodynamics involved in the formation
of a massive electron beam precipitating from the tenuous corona.
Note the invocation of a potential drop, but in a
CSHKP global picture.
Such an electrostatic force would not be available in any single-fluid MHD
simulation.
