Published in 2019 at "Astronomy Reports"

DOI: 10.1134/s1063772919110052

Abstract: 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… read more here.
