Fig. 2


Age, distance and spectral type of all the stars in our sample. Table 1 gives the individual properties of each target. The size and color of the symbols correspond to the spectral type of each target: bluer colors for earlier spectral types and redder colors for later spectral types. The points grouped at 125 Myr correspond to stars without a published age, as described in Sect. 2.
