Description
The lithium depletion boundary (LDB) is a reliable method to obtain ages for open clusters and stellar associations. So far it has been applied to clusters and associations younger than 150 Myr where the LDB takes place among the late-M type population. In older clusters the LDB is expected to move toward fainter luminosities and cooler temperatures, i.e. the realm of the L dwarfs. Using OSIRIS at the Gran Telescopio Canarias we have started a search for the Li~I 670.8~nm~ resonance doublet in L dwarfs with high probability of membership in the Hyades. In this presentation we show our first results which allow us to derive the first estimate of the Hyades age using the LDB method.
