The Classical Hyades Lithium Problem Resolved

Recent observations of Hyades stars indicate an enhanced oxygen-to-iron ratio in comparison to the Sun. We show that the impact of such an oxygen enhancement on the predictions of pre-main-sequence lithium burning, via interior opacities, is quite substantial. For the first time, self-consistent predictions of the G and K dwarf (Li, T(eff)) relationship for the Hyades match the observations. Other elements which could be of importance in this regard, for any cluster, are also identified.
