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 ...

Eclipse Instrumentation for the Solar Corona
Applied Optics, 1970The expedition of the Harvard College Observatory, the Smithsonian Astrophysical Observatory, and the National Geographic Society to Miahuatlán, Mexico, to observe the total solar eclipse of 7 March 1970, is described. Instrumentation included a coronal spectrograph, television cameras recording on videotape, telescopes for photography of coronal ...

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

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.

Alfvén Waves in the Solar Corona
Science, 2007Alfvén waves, transverse incompressible magnetic oscillations, have been proposed as a possible mechanism to heat the Sun's corona to millions of degrees by transporting convective energy from the photosphere into the diffuse corona. We report the detection of Alfvén waves in intensity, line-of-sight velocity, and linear polarization images of the ...
