Ross 128 -- GL 447A possible activity cycle for a slow-rotating fully-convective star

Context. Long-term chromospheric activity in slow-rotating fully-convective stars has been scarcely explored. Ross 128 (Gl 447) is a slow-rotator and inactive dM4 star which has been extensively observed. It hosts the fourth closest extrasolar planet. Aims. Ross 128 is an ideal target to test dynamo theories in slow-rotating low-mass star. Methods. To characterize the magnetic activity of Ross 128 we study the SK indexes derived from CASLEO, HARPS, FEROS, UVES and XSHOOTER spectra. Using the Generalized Lomb-Scargle and CLEAN periodograms, we analyze the whole SK time-series obtained between 2004 and 2018. We perform a similar analysis for the Na I index and we analyze its relation with the SK-index. Results. From both indexes, we obtain a possible activity cycle with a 5-year period, which is one of a small handful of activity cycles reported for a slow-rotating fully convective star.
