Resumen:
We study the possible excess of lithium (Li) depletion found in stars with planets when they are compared with similar stars (same range of T and log g) without planets. Moreover; we analyzed the possible relation between Li abundances and the stellar activity suggested by some authors. We used high-resolution spectra (R 110.000) of FGK stars with and without planets taken with the HARPS (High Accuracy Radial velocity Planet Searcher) spectrograph; installed at the 3.6 m ESO telescope.
