Determination of the iron content of Cepheids from the shape of their light curves
We present the study of the metallicity dependence of the Fourier amplitude ratios R21 and R31 for the light curves of short-period Galactic classical Cepheids in B, V, RC and IC bands. Based on the available photometric and spectroscopic data, we determined the relations between the atmospheric iron abundance, [Fe/H], and the Fourier parameters
