cds-question@unistra.frdwarf-starsmultiple-starssolar-system-planetsradial-velocityWe report the discovery of a super-Earth orbiting the star GJ 536 based on the analysis of the radial-velocity time series from the HARPS and HARPS-N spectrographs. GJ 536 b is a planet with a minimum mass Msini of 5.36+/-0.69M_{Earth}_ 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.2017A&A...597A.108Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/597/A108CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/549/A109 : HARPS XXXI.
