Confined pseudo-shocks as an energy source for the active solar corona

Stangalini, Marco; Kayshap, Pradeep; Dwivedi, Bhola N. +7 more

The Sun's active corona requires an energy flux of 10³ W m^-2 to compensate for radiative losses and to maintain its high temperature¹. Plasma moves in the corona through magnetic loops^2,3, which may be connected with the flows in and around sunspots^4-6. Global energizing processes (for example…
