Lithium abundance of single stars with age computed by detailed modelling with the amp code. The stars KIC 10644253, KIC 6116048, KIC 7680114, and KIC 3656476 are plotted as black hexagon, yellow diamond, red square, and magenta pentagon, respectively. For KIC 3656476 the upper limits of the measured A(Li) is shown. TGEC-evolutionary tracks are shown in red, and yellow represents the theoretical evolution of A(Li) for models of the indicated mass with [Fe/H] = +0.2, and − 0.2 dex, respectively. The black dashed evolutionary track depicts the evolution of Li calculated by do Nascimento et al. (2009), and the solar marker depicts the measured A(Li_⊙) and age of the Sun.
