Resumen:
The aim of this work is to analize the possible difference in the levelsof activity showed by stars with and without planets. Several authorshave suggested that stars with planets, in particular those withhot-Jupiter-like planets, have activity levels greater than those showedfor stars of the same spectral class, but without planets. In thiscontribution we present the analysis of chromospheric activity indexesfor 353 objects. To do so, we used high-resolution spectra () of F-, G-,and K-type stars taken with the High Accuracy Radial velocity PlanetSearcher spectrograph, installed at the 3.6 m ESO telescope. We do nofind a significant difference in the activity indexes of stars with andwithout planets.
