Solar coronal heating by magnetosonic waves

Monthly Notices of the Royal Astronomical Society, 2001
Solar coronal heating by magnetohydrodynamic (MHD) waves is investigated. ultraviolet (UV) and X-ray emission lines of the corona show non-thermal broadenings. The wave rms velocities inferred from these observations are of the order of 25–60 km s−1. Assuming that these values are not negligible, we solved MHD equations in a quasi-linear approximation,

Unveiling the mystery of solar-coronal heating

Physics Today, 2023
Miniature flares recently discovered by probes that have approached the Sun’s surface are helping physicists understand how the Sun’s corona reaches temperatures of millions of kelvin.

Solar coronal heating by plasma waves

Journal of Plasma Physics, 2009
AbstractThe solar coronal plasma is maintained at temperatures of millions of degrees, much hotter than the photosphere, which is at a temperature of just 6000 K. In this paper, the plasma particle heating based on the kinetic theory of wave–particle interactions involving kinetic Alfvén waves and lower-hybrid drift modes is presented.

Solar Coronal Loops and Coronal Heating Models

AIP Conference Proceedings, 2005
Ever 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, 1991
A 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, 2006
The 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, 2010
A 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

1965
We 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.
