Evolution of lithium abundance in solar twins. Solid lines indicate our models of early depletion scenario with different overshooting values (see Table 1) leading to significant lithium depletion during the pMS stage. The dashed line qualitatively illustrates the traditional scenario with significant lithium depletion during the stage of MS. Black circles are solar twins taken from (Meléndez et al. 2014). Grey and unfilled circles and triangles are twins from (Carlos et al. 2016); triangles are the upper limits on lithium abundance; three unfilled circles are twins-exceptions which can be interpreted in the framework of the early depletion scenario.
