GJ 625 b is a planet with a minimum mass Msini of 2.82±0.51 MEarth with an orbital period of 14.628±0.013 days at a distance of 0.078AU of its parent star. The host star is the quiet M2 V star GJ 625, located at 6.5pc from the Sun. We find the presence of a second radial velocity signal in the range 74-85 days that we relate to stellar rotation after analysing the time series of CaII H&K and Hα spectroscopic indicators, the variations of the FWHM of the CCF and and the APT2 photometric light curves. We find no evidence linking the short period radial velocity signal to any activity proxy. Description: The star GJ 625 is part of the Bonfils et al. (2013, Cat. J/A+A/549/A109) sample and has been extensively monitored since mid-2004. We have used 140 HARPS-N spectra taken over 3 yr and more than 100 nights of EXORAP photometry. HARPS-N (Cosentino et al. 2012, in Ground-based and Airborne Instrumentation for Astronomy IV, SPIE,8446, 84461) is a fibre-fed high-resolution echelle spectrograph installed at the Telescopio Nazionale Galileo in the Roque de los Muchachos Observatory (Spain). Along with the HARPS-N spectra we have 2.6yr of B, V, R, and I-band photometric data collected at the INAF-Catania Astrophysical Observatory with an 80cm f/8 Ritchey-Chretien robotic telescope (APT2) located at Serra la Nave on the Mt. Etna .
