GJ 536 b is a planet with a minimum mass Msini of 5.36±0.69M with an orbital period of 8.7076±0.0025 days at a distance of 0.066610(13) AU, and an orbit that is consistent with circular. The host star is the moderately quiet M1 V star GJ 536, located at 10 pc from the Sun. We find the presence of a second signal at 43 days that we relate to stellar rotation after analysing the time series of Ca II H&K and Halpha spectroscopic indicators and photometric data from the ASAS archive. We find no evidence linking the short period signal to any activity proxy. We also tentatively derived a stellar magnetic cycle of less than 3 years. Description: The star GJ 536 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 146 HARPS spectra taken over 11.7 yr along with 12 HARPS-N spectra taken during April and May 2016. HARPS (Mayor et al., 2003Msngr.114...20M) and HARPS-N (Cosentino et al. 2012, in Ground-based and Airborne Instrumentation for Astronomy IV, SPIE, 8446, 84461) are two fibre-fed high-resolution echelle spectrographs installed at the 3.6m ESO telescope in La Silla Observatory (Chile) and at the Telescopio Nazionale Galileo in the Roque de los Muchachos Observatory (Spain), respectively.
