Location of γ Dor stars on CMD with best-fitting isochrone. The large circles show the γ Dor stars with clear period spacings, colour-coded by their buoyancy travel time (left panel) or near-core rotation rates (right panel). The black dots are the other cluster members, and the grey solid line is the best-fitting isochrone. We also indicate the masses of the models on the right edges of each panel. In the left panel, we show the TIC numbers of the stars.
