cds-question@unistra.frmultiple-starsexoplanetsradial-velocityWe report the detection of two exoplanets and a further tentative candidate around the M-dwarf stars Gl96 and Gl617A, based on radial velocity measurements obtained with the SOPHIE spectrograph at the Observatoire de Haute-Provence. Both stars were observed in the context of the SOPHIE exoplanet consortium's dedicated M-dwarf subprogramme, which aims to detect exoplanets around nearby M-dwarf stars through a systematic survey. For Gl96 we present the discovery of a new exoplanet at 73.9d with a minimum mass of 19.66 earth masses. Gl96b has an eccentricity of 0.44, placing it among the most eccentric planets orbiting M stars. For Gl617A we independently confirm a recently reported exoplanet at 86.7d with a minimum mass of 31.29 earth masses. Both Gl96 b and Gl617Ab are potentially within the habitable zone, though the high eccentricity of Gl96 b may take it too close to the star at periapsis.2018A&A...618A.103Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/618/A103CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/618/A103https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/618/A103http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/618/A103https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/618/A103https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/618/A103http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/618/A103GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/618/A103/table1 (Stellar parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/618/A103/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/618/A103/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/618/A103/table1?GETtext/xml+votable180.050000true244.178110867.23884190.0055555555555555566/2515 11671https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/618/A103?format=asciidefaultJ/A+A/618/A103/table1Stellar parametersrecnoRecord number assigned by the VizieR team.
