Left: stellar evolution tracks assuming moderate convective core overshoot, α_c = 0.2 and initial rotation rates of 0,100,200, and 400 km s^-1 denoted by black solid, green dashed, blue dot-dashed, and magenta dotted lines, respectively. Right: stellar evolution tracks assuming zero rotation and convective core overshoot, α_c = 0,0.2, and 0.4 as denoted by black solid, green dashed, and blue dot-dashed lines, respectively.
