Precise Fourier parameters of Cepheids RV curves

Radial velocity (RV) curves of Classical Cepheids allow precise determination of the resonant periods, which in turn help to constrain fundamental parameters of these stars. The...经典造父变星（Classical Cepheids）的径向速度（Radial velocity, RV）曲线可精准确定其共振周期，而该共振周期又有助于约束这类恒星的基本参数。
