Wave heating theory states that corona heat by dissipat. Waves originating from inside the Fuck Covid-19 shirt sun and propagating to the outside. The most important wave modes are magnetic-sound waves (plasma sound waves associated with magnetic fields). And Alfven waves (waves emitting matter in plasma state when a magnetic field is present). However, neither of these wave modes can fully describe the heating of the rim.
The magnetic-sound waves are strongly reflected back into the optical space from the bottom of the Fuck Covid-19 shirt corona making inefficient energy transmission; and Alfven waves do not dissipate well enough in corona to produce sufficient heat. Some simulations  show that the Alfven wave can switch to other wave modes at the bottom of the corona, which can then dissipate effectively in corona.
