Resumen:
We analyze the long-term activity of seven stars which host near Jupiter-like planets (0.40Mj < Mp < 11Mj and a<1 UA). To do so, we computed the Mount Wilson index S from a set of high-resolution spectra obtained with the spectrograph REOSC of the telescope 2.15 m at CASLEO. We study the long-term chromospheric activity of these stars and its dependence with several orbital parameters of the planet. We also compare these levels of activity with the Mount Wilson indexes of stars of similar spectral class and type without planets.
