Predictions for 7 M_⊙ Cepheids on the second crossing as function of ω. Panels A) through G) show bolometric magnitude, luminosity, effective temperature, surface gravity, equatorial velocity, age, and lifetime. The range of values during the IS crossing is shown as black lines for the IS definition by Bono et al. (2000b), and as a light gray shade for the IS from Tammann et al. (2003). On the second crossing, all parameters increase during the evolution along the blue loop, except for τ_Cep, which shows the duration of the IS crossing. Triangles in panel E) show the extreme values for surface velocity at the beginning of the blue loop near the Hayashi track (minimal) and at its greatest extension (maximal).
