Scientific paper

This paper reports results of numerical studies of macroturbulence broadening on solar LTE intensity profiles with a view toward applying the results toward other solar-type stars. The results are compared for five different velocity models with spatially and temporally averaged center-to-limb observations. The comparisons are made through the curve of the line-width correlation and through the curve of the line-shape diagram. For mildly saturated lines (about 120 mA), the solar macrovelocities are the most important of the velocity scale sizes in determining the shape of the line core. The unsaturated weak lines and the curve of the line-width correlation do not discriminate between the two scale sizes of broadening, as suggested by other studies. High-accuracy photoelectric data for Procyon used in the curve of the line-shape indicates that macroturbulence broadening dominates and that the microturbulence component is about 1 km/s.
