Variations in the pressure scale height HP (dashed line) and the radius of the extended convective core Rc (solid blue line) with age for a 1.3 M Cesam2k model with solar metallicity, a solar-calibrated value for the mixing length, Y0 = 0.26, and αov = 0.1. The gray solid line indicates the Schwarzschild limit.
