Kiel diagram and the CMD for the 256 metal-rich stars with 0.15 < [Fe/H]< 0.3 and 2 < Age (Gyr) < 4. For illustration purposes, PARSEC stellar isochrones for ages 2, 3, 3.5, 4, and 5 Gyr, and [Fe/H]= 0.1, 0.2, and 0.3 dex are included. The CMD uses JHKs absolute magnitudes from 2MASS, which were used as inputs for StarHorse to estimate ages. These stars most probably formed during the epoch of bar formation.
