The magnetic origin of the solar wind and CMEs
The polytropic fluid provides an elementary but conceptually complete understanding of natural failings of gravitational confinement in the open atmosphere of the Sun, giving rise to the solar wind filling interplanetary space out to beyond Pluto, and the almost daily expulsions of CMEs from the low corona. Magnetic fluxes continually emerging from the interior solar dynamo play central roles. The ubiquitous Parker spontaneous current-sheets by their resistive dissipation maintain the million-degree hot, fully ionized corona as a near-perfect conductor of heat and electricity. Excessive accumulated magnetic fluxes in the corona drive CMEs with a self-similarity shared with solar gravity. These pretty hydromagnetic properties will be described with a minimum of mathematical details.
