On the Pulsation Mode of s-Cepheids
Abstract
The location of s-Cepheids in the H-R diagram, derived from observations is compared with the theoretical blue edges of fundamental and first harmonic mode pulsation. Results suggest that SMC s-Cepheids are first harmonic pulsating stars. There is some evidence that SMC s-Cepheids are brighter than other SMC Cepheids, supporting this conclusion.
