Metallicity effects on distances based on double-mode Cepheids

Year: 2005

Type: preprint

Abstract: We test the effect of systematic metallicity difference between the two types of double-mode Cepheids in the Magellanic Clouds. We show that lowering the metallicity for the short-periodic Cepheids leaves the distances at their canonical values and, at the same time, improves the agreement between the observed and model periods.
