Solar XUV Limb Brightening Observations. I: The Lithium-Like Ions
Abstract
OSO-IV observations of the equatorial limb brightening of XUV resonance lines of NV, O VI, Ne VIII, Mg X and Si XII are interpreted with a modified version of a coronal model developed by Dupree and Goldberg (1967). Good agreement is obtained between the observed limb brightening and that predicted by the model. The sensitivity of the predicted limb-brightening curves to changes in parameters describing the model is discussed. Coronal abundances for N, O, Ne, Mg, and Si are obtained.
