The solar corona is an extremely hot (106 K or about 0.1 keV), almost fully ionised plasma which extends from a few thousand km above the Sun’s visible surface or photosphere (6000 K) to where it freely expands into the solar system as the solar wind.

Despite of the large number of models and mechanisms proposed in the literature, the problem of the heating of the solar corona is still unsolved and represents one of the challenge of solar physics. In this context, a basic question to be addressed by any viable theoretical model concerns understanding the mechanism capable of transferring ...

THE difficulties which have so far been experienced in working out a physical theory of the solar corona (vide Rosseland, “Theoretical Astrophysics”, Chap. 14) have apparently been increased by the discovery of Grotrian and Edlen that many of these lines are due to forbidden transitions of highly stripped atoms of iron and nickel having the ...

The connection between things that happen on the sun and things that happen on the earth has been manifest for so long that the sun has often been worshipped as a god with power over terrestrial destinies. Since the dawning of the scientific age, the connections have been regarded as more physical than supernatural, but a number of them have been long ...

Annual Review of Astronomy and Astrophysics, 2001
We focus on new observational capabilities (Yohkoh, SoHO, TRACE), observations, modeling approaches, and insights into physical processes of the solar corona. The most impressive new results and problems discussed in this article can be appreciated from the movies available on the Annual Reviews website and at http://www.lmsal.com/pub/araa/araa.html .

The structure of the quiet solar corona is considered, excluding the effect of magnetic active regions. Starting with a simple one-dimensional geometry, models are derived both from ab initio theory and from analysis of spectral line intensities. To overcome the inconsistencies which arise, account is taken progressively of two-dimensional effects; the

Astrophysics and Space Science, 1996
The solar corona, and the coronae of solar-type stars, consist of a low-density magnetized plasma at temperatures exceeding 106 K. The primary coronal emission is therefore in the UV and soft x-ray range. The observed close connection between solar magnetic fields and the physical parameters of the corona implies a fundamental role for the magnetic ...
