Positions of the analysed stellar models with Γ_max> 0.9 in the Hertzsprung-Russell (HR) diagram (coloured dots). Models with Γ_max> 1.1 are coloured dark blue. The solid lines show the evolutionary tracks of non-rotating stellar models (Köhler et al. 2015). The initial masses are marked in units of solar mass. The dashed line corresponds to the zero-age main-sequence of the non-rotating models. The hot and the cool edges of the S Dor instability strip from (Smith et al. 2004) are indicated with thick dotted lines. The interior structures of the models marked with yellow diamonds are shown in Appendix D.
