Solar Coronal Loops and Coronal Heating Models
AIP Conference Proceedings, 2005Ever since it was realized, some sixty five years ago, that the solar corona is three orders of magnitude hotter than the underlying photosphere, scientists have puzzled over the reason for these extreme conditions. A number of plausible ideas have been put forward, including the dissipation of magnetohydrodynamic (MHD) waves and the dissipation of ...

Mechanisms of solar coronal heating
Plasma Physics and Controlled Fusion, 1991A major problem in astrophysical plasma physics is to explain how the outer atmosphere, the corona, of the Sun is heated to temperatures of millions of degrees Kelvin. It is accepted that the heating mechanism is magnetic, with the energy source being turbulent motions below the solar surface.

Nonlinear aspects of the solar coronal heating
Plasma Physics and Controlled Fusion, 2006The heating of the solar coronal plasma has remained one of the most important problems in solar physics. An explanation of the electron and ion heating rests on the identification of the energy source and appropriate physical mechanisms via which the energy can be channelled to the plasma particles.

Solar Coronal Heating via Alfvén Wave Turbulence
AIP Conference Proceedings, 2010A short review is given about the self‐consistent MHD model of solar coronal heating recently proposed by Bigot et al. (2008) in which the dynamical effect of the background magnetic field along a coronal structure is taken into account through exact results from Alfven wave turbulence.

Coronal Heating and Solar Wind
1965We have now to consider the heat carried mechanically in the chromosphere and corona and hope to explain in this way the heating of these two regions. It can be said that the present theories give a picture of the temperature in the chromosphere and corona which show all the main features of the observed temperature distribution.

Solar Coronal Heating by Dissipating Current Sheets
Physica Scripta, 2004It is shown that the lower-hybrid turbulence produced by the lower-hybrid-drift wave instability at current sheets can heat electrons and ions in the solar corona.

To the problem of solar coronal heating
Astronomy Letters, 2007We consider the adequacy of various solar coronal heating models. We show that the correlation between the intensity of the coronal Fe XIV 530.5 nm green line and the calculated magnetic field strength in the solar corona can be a useful tool for this purpose.

Solar Coronal Heating by Magnetic Flux Interaction
1994A Converging Flux Model for heating X-ray bright points (and possibly coronal loops and coronal holes) is proposed which also accounts for the cancelling magnetic features that are usually observed to be present in the photosphere below bright points.

Nonlinear wave heating of solar coronal loops.
Astronomy and Astrophysics, 1997The heating of magnetically closed structures (loops) in the solar corona by the resonant absorption of incident waves is studied by means of numerical simulations in the framework of nonlinear resistive magnetohydrodynamics (MHD). It is shown that the dynamics in the resonant layer is indeed very nonlinear for typical coronal parameters. The effect of

Coronal heating and solar activity: The role of waves
Advances in Space Research, 1993Abstract Coronal heating and solar activity are manifestations of the complex interaction between the magnetic field and the photospheric plasma motions. As a result of such an interaction magnetohydrodynamic waves are generated: their dissipation may provide the basic physical mechanism to heat the corona.
