Fig. 7

thumbnail

Top panel: observed stars in the age-[Fe/H] plane, colour-coded with their Teff. Bottom two panels: highest possible Teff for a given age and [Fe/H] obtained from the stellar evolution tracks without (middle) and with (bottom) photometry and log g cuts. Selected curves of constant Teff are given for reference. For Teff ≤ 6500 K, the highest “observable” values of Teff do not depend on the cuts imposed on the sample and are simply the result of stellar evolution effects.
