Microturbulent速度在G的大气光谱类明星

作者(年代):咱Samedov和马Jafarov

microturbulence调查在G的大气光谱类恒星大气模型。microturbulent速度确定的基础上,从观察和测量值的比较FeII理论上计算等效宽度的线。It has been found that the microturbulent velocity ( ) depends on the surface gravity (g) in the atmospheres of the star: decreases with increasing g. The microturbulent velocity is less in the stars with intense atmosphere.
