Highly ionized atoms in space ; or highly ionized atoms, what are they teaching us about the solar coronal heating processes ?
TL;DR: In this paper, a thorough review of spectral line intensities implies that plasmas in different parts of the upper solar atmosphere are transiently ionizing and are consistently associated with increased electron density.

The physical conditions in inner corona derived from spectral data of the solar eclipse on 7 March, 1970
E. A. Gurtovenko,K. V. Alikayeva +1 more
TL;DR: In this paper, the spectrum of the solar corona obtained during the eclipse of 7 March, 1970 has been studied from the analysis of the line halfwidths and it is concluded that the emission of coronal lines of various groups arises in different volumes of the corona.

High Resolution Search for Iron Line Emission from Sco X-1
TL;DR: In this paper, it has been shown that all cosmically abundant elements up to iron will be predominantly ionized and that iron will retain only K shell electrons, and it has therefore been suggested that observation of the characteristic emission of helium-like Fe XXV or of hydrogen-like F XXVI by Sco X-1 will provide definite confirmation of its thermal nature.

The acceleration of heavy nuclei in solar flares
TL;DR: In this paper, the overabundance of heavy nuclei in solar cosmic rays of energy approximately 5 Mev/nucleon is explained by taking into account the pre-flare ionization states of these nuclei.

Major radius compression in a large Tokamak
B Green,P Noll,J Sheffield +2 more
TL;DR: In the presence of certain plasma loss mechanisms, major radius compression of a reduced size may give higher temperatures than those obtainable in full aperture Tokamak operation as mentioned in this paper, and the authors give compression scaling laws of temperature for various loss mechanisms and identify situations where major radius compressions may be usefully applied.
