LETTERS TO PROGRESS IN PHYSICS The Liquid Metallic Hydrogen Model of the Sun and the Solar Atmosphere V. On the Nature of the Corona

The E-corona is the site of numerous emission lines associated with high ionization states (i.e. FeXIV-FeXXV). Modern gaseous models of the Sun require that these states are produced by atomic irradiation, requiring the sequential removal of electrons to in-finity, without an associated electron acceptor. This can lead to computed temperatures in the corona which are unrealistic (i.e. ∼30–100 MK contrasted to solar core values of ∼16 MK). In order to understand the emission lines of the E-corona, it is vital to recognize that they are superimposed upon the K-corona, which produces a continuous spectrum, devoid of Fraunhofer lines, arising from this same region of the Sun. It has been advanced that the K-corona harbors self-luminous condensed matter (Robitaill
