Evolution of the corotation radius, r_corot, as a function of the rotation rate for ε = 0 (top) and ε = 0.3 (bottom). The corotation radius of the most unstable mode is represented with a blue line (numbers above the line specify the corresponding azimuthal number, m). For comparison, grey lines show the PNS radius, r_PNS, the gain radius, r_gain, the radius of the Brunt–Väisälä frequency maximum, r_BV, and the shock radius, r_sh. With both values of the dissociation, the corotation radius of the most unstable mode is close to r_BV for slow rotation and moves away for higher rotation rates (j > 30%).
