To understand the evolution of giant stars, it is important to pin down the masses for Cepheids. The 7– to 10–day “bump” Cepheids imply lower than evolutionary mass (60%). Recent theoretical work, though, indicates that for Cepheids with periods of 15 to 16 days, the best understanding of the light curves results from using evolutionary masses.
