Stellar activity cycles of FGK dwarfs and their relation with radial velocity

Resumo
HARPS spectra of a sample of 8 stars for a 5-year period was used to determine three chromospheric activity indices, obtain high-precision radial-velocities, and compute the CCF parameters BIS, FWHM and Contrast. All these parameters were compared in order to find any correlations.
