In the original article, there was a mistake in Figure 3 as published.
Figure 3. Scatter plots showing core radius (Rc) vs core mass (Mc) for best-fit models with convective cores obtained using grid B (Run I). Top left is color-coded according to the model mass (M), top right is color-coded according to the initial metal mass fraction (Z), and bottom panel is color-coded according to the overshoot parameter (f ov).
This figure aimed at exploring trends regarding the contribution from the dominant model properties (i.e., mass, initial metal mass fraction, and overshoot parameter) toward the convective core sizes of the best-fit models of α Centauri A. However, the data plotted in Figure 3 in the original article represents the models with convective cores that satisfy a probability threshold required to fit the sets of observables (i.e., seismic observables, classical observables, and an interferometric radius), instead of showing the best-fit models with convective cores that satisfy the sets of observables within 1σ. The corrected Figure 3 appears below.
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
