Distribution of eccentricities and velocities with respect to the local standard of rest V_LSR (upper and bottom panels, respectively) for y-exαFe and young [α/Fe]-normal dwarfs stars (blue and grey histograms, respectively). The green histogram shows the distribution of old (age ≥ 8 Gyr) stars with [α/Fe] ≥ dex. The magenta histogram shows the distribution of 40 y-exαFe stars with A(Li) > A(Li)_SBBN = 2.65. All the histograms are scaled to have the same height and we show the distributions for the main sample only for the purpose of better visibility.
