Zusammenfassung |
This paper discusses
the possibility that heating of the solar corona in open field-line
regions emanating from coronal holes is due to a nonlinear cascade, driven
by low-frequency or quasi-static magnetohydrodynamic fluctuations.
Reflection from coronal inhomogeneities plays an important role in
sustaining the cascade. Physical and observational constraints are
discussed. Kinetic processes that convert cascaded energy into heat must
occur in regions of turbulent small-scale reconnection, and may be similar
in some respects to ion heating due to intense electron beams observed in
the aurora. |
