On lithium removal from G dwarfs

Lithium is observed to be progressively removed from the atmospheres of main-sequence G stars. In the presence of enough mass loss, this removal can be explained by the eventual dilution of the material in the surface convective zone by lithium-free matter which enters this zone from below and which...
