Li evolution as a function of log(g) (left panel), T_eff (middle panel), and stellar mass (right panel). Three clusters with similar metallicity but different ages are displayed. The red-filled dots are our Rup 147 (2.5–3.0 Gyr) sample stars with NLTE correction, the blue-filled squares are NLTE-corrected NGC 752 (∼1.6 Gyr) single stars originally from Castro et al. (2016), and the grey-filled diamonds are Li-corrected M 67 (∼3.7 Gyr) data from Pace et al. (2012). The Li abundance derived from chondrite meteorites (A(Li)=3.25 dex, Grevesse et al. 2007) is indicated by a dashed line.
