| Metallicity effects on distances based on double-mode Cepheids (2005) | |||||||||
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..
