Resumen:
In this work we studied the long-term activity of two solar- type stars. Using our mid-resolution spectra obtained quarterly at CAS- LEO from 1999 and the spectra acquired continuosly at the CTIO (Chile) from 2008 to date. For the star HD 130948 we detected a possible activity cycle of ∼5 years and for HD 128621 (α Cen B) we confirmed its 8-year activity cycle previously reported.
