详细
Microturbulence in the atmospheres of F stars is studied using model atmospheres. The microturbulence velocity is determined by comparing calculated and observed equivalent widths of Fe II lines. The line equivalent widths were measured using the DASA code developed at the Crimean Astrophysical Observatory of the Russian Academy of Sciences. An inverse dependence of the microturbulence velocity ξt on the gravity g in the stellar atmospheres is found; i.e., ξt decreases with increasing g.
