Colour magnitude diagram of the observed high-speed stars. The stars discussed in Paper I are in blue, which were observed in ESO period 104, and those observed in period 105 and 106 are in red. We provide PARSEC isochrones (Bressan et al. 2012) of metallicity 0.0 (grey), −1.0 (yellow), and −2.0 (green) of different age ranges. The age difference between consecutive isochrones of any given metallicity is 1 Ga. The apparently young stars observed in periods 105 and 106 are identifiable with an open square around the symbol.
