论文摘要
提出了一种原始的估计投影旋转速度的方法，$ vsini $和大型速度的速度，$ v _ {\ rm mac} $，呈现出进化的M巨星。它基于频谱合成和多行分析工具的使用。目的是将观测值的平均线曲线与合成光谱的平均线曲线拟合。该方法应用于红色巨星RZ ARI，结果$ v \ sin i $ = 6.0 $ \ pm $ 0.5 km/s和$ v _ {\ rm mac} $ = 2.0 $ \ pm $ \ pm $ 1.0 km/s/s/s。
An original method of estimating the projected rotational velocity, $vsini$, and the macroturbulent velocity, $v_{\rm mac}$, of evolved M giant stars is presented. It is based on the use of spectrum synthesis and multi-line analysis tools. The goal is to fit the mean line profile of observations with that of synthetic spectra. The method is applied to the red giant star RZ Ari and the results $v\sin i$ = 6.0 $\pm$ 0.5 km/s and $v_{\rm mac}$ = 2.0 $\pm$ 1.0 km/s are obtained.
