Description

We have derived [Fe/H] and [α/Fe] abudnances for Cepheids with Galactocentric distances of 11 to 17 kpc. The stars are as metal-poor as much older open clusters at comparable distances. Like the clusters, and despite their youth, the Cepheids also show enhanced [α/Fe] abundances indicating enhanced contributions from SNe II relative to the Solar neighborhood
