| Abstract: |
Observations of photospheric line asymmetries in 12 G and 11 K dwarfs, particularly the Fe I 6151.62 A line, are examined to determine the amplitudes and shapes of the bisectors. Bisector shapes are compared for magnetically inactive and active stars, and correlations between the slope and the stellar angular velocity are investigated. G stars have increasingly negative slopes with larger stellar angular velocity while K-star slopes become more positive, an effect which is shown to be consistent with recent hydrodynamical models. |
