Dependence of Microturbulence on Absolute f-Values

Abstract

A study of 51 main-sequence A to G stars shows that microturbulent velocities derived using the Kiel absolute f-values for Fe I are generally smaller than those determined with the Corliss and Warner f-values. Mso, in this spectral range excitation temperatures for Fe I come out to be higher by about - 0. in 0. Key words: microturbulence - oscillator strengths - Fe I f-values
