Context. Rotational velocity, lithium abundance, and the mass depth of the outer convective zone are key parameters in the study of the processes at work in the stellar interior, in particular when examining the poorly understood processes operating in the interior of solar‐analog stars. Aims. We investigate whether the large dispersion in the observed lithium abundances of solar‐analog stars can be explained by the depth behavior of the outer convective zone masses, within the framework of the… Expand
