Lithium abundance and equivalent width vs. T_eff plots. Left: non-LTE Li abundance, log ϵ(Li), versus effective temperature, T_eff. The targets of this work (blue filled dots) are plotted together with the targets from Biazzo et al. (2022) in grey open squares and the members of the Pleiades (~100 Myr; Sestito & Randich 2005), Hyades (~600 Myr; Cummings et al. 2017), and M67 (~4.5 Gyr; Pasquini et al. 2008) clusters (in yellow crosses, red diamonds, and green triangles, respectively). Right: lithium equivalent width (EW_Li) versus effective temperature. Here, the empirical model isochrones by Jeffries et al. (2023) at 50, 100, 150, 200, 300, 400, 500, 600, 700, 800, 900 Myr, 1, 1.5, and 2 Gyr are overplotted.
