Resumen:
In this work, we study the long-term activity of a sampleof stars which host near Jupiter-like planets (0.40MJ < Mp < 11MJand a<1 UA). To do so, we computed the Mount Wilson index S froma set of high-resolution spectra obtained with the spectrograph REOSCof the telescope 2.15 m at CASLEO between 2002 and 2012. In thiswork, we analyze long-term chromospheric activity of these stars andits dependence with several orbital parameters of the planet. We alsocompare these levels of activity with the Mount Wilson indexes of starsof similar spectral class and type without planets.
