Fig. 9


Metallicity as a function of age for stars in the sample. Symbols as in the top panel of Fig. 8. When thin disk metal-poor stars (yellow dots) are not considered, the age–metallicity relation of thick disk stars (blue solid circles) is obvious. The two objects at [Fe/H] < −1.0 dex and age ~ 9 Gyr are HIP 54641 and HIP 57360. See text for details.
