Under the assumption that grain sedimentationcan lead to an enhancement of heavy elements in the central regions of proto-stars, we present the evolution of stellar models with metal-rich cores. The resulting isochrones can explain the “double-gap” clusters NGC2420 and NGC2506, without destroying the agreement for other clusters.
