Predicted rotation rates and nitrogen (left) and carbon (right) abundance for Cepheids crossing the instability strip for the first time. Predictions are based on three initial rotation rates: v = 50 (green x’s), 100 (blue stars), and 200 km s-1 (magenta squares), while the horizontal line represents the abundance measured by Usenko et al. (2005).
