Ionization and Kinematics of Yellow-Line Coronal Regions

Abstract

The authors computed the ionization of Ca XV from observations of the strengths of the coronal lines lambda 5694 and lambda 5446, and the neighboring regions of the continuum they then compared this with a theoretical ionization curve including dielectronic recombination. Discrepancies are discussed and explanations suggested in the form of turbulence and/or ordered mass motion. Finally estimates are calculated of the dimensions of the observed condensations along the line of sight.
