Coronal heating problem

The Sun's corona is millions of degrees Kelvin hotter than the main body of the Sun (reaching temperatures of up to 10 MK). A number of possible mechanisms have been proposed to explain why. They include:

• slow and fast magneto-acoustic surface waves • current (or magnetic field) dissipation • microflares/transients • mass/particle flows • magnetic flux emergence • afven body waves.

As yet, none has been confirmed as the cause.
