The Solar H and K Lines of Ionized Calcium

Conference paper

Abstract

Photographic observations of the mean H and K profiles are given for several positions across the solar disk (0.1 < μ <.6). The core profiles of H and K are nearly identical at the same position on the sun.

Estimates of the mean Doppler width and the depth of formation of the K2 emission peaks are given. A more elaborate analysis confirms that the K2 peaks are formed in a relatively shallow layer (τ 0 ~ 3) in which the Doppler width decreases rapidly inward. The relevance of these conclusions to current attempts to predict theoretically the H and K profiles is discussed.
