cds-question@unistra.frmultiple-starsexoplanetsgiant-starsphotometryvisible-astronomyExomoons represent a crucial missing puzzle piece in our efforts to understand extrasolar planetary systems. To address this deficiency, we here describe an exomoon survey of 70 cool, giant transiting exoplanet candidates found by Kepler. We identify only one exhibiting a moon-like signal that passes a battery of vetting tests: Kepler-1708b. We show that Kepler-1708b is a statistically validated Jupiter-sized planet orbiting a Sun-like quiescent star at 1.6au. The signal of the exomoon candidate, Kepler-1708 b-i, is a 4.8{sigma} effect and is persistent across different instrumental detrending methods, with a 1% false-positive probability via injection-recovery. Kepler-1708b-i is ~2.6 Earth radii and is located in an approximately coplanar orbit at ~12 planetary radii from its ~1.6au Jupiter-sized host. Future observations will be necessary to validate or reject the candidate.2022NatAs...6..367Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/NatAs/6.367CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/NatAs/6.367https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/NatAs/6.367http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/NatAs/6.367https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/NatAs/6.367https://vizier.iucaa.in/viz-bin/votable?-source=J/other/NatAs/6.367http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/NatAs/6.367GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/NatAs/6.367/table2 (Fundamental stellar parameters inferred for the cool-giant host stars in our using an isochrone analysis)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/NatAs/6.367/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/other/NatAs/6.367/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/NatAs/6.367/table2?GETtext/xml+votable180.050000true292.658442538.34539920.0055555555555555566/14579 14583 14590-14591 14735 14750 14753-14754 14758 14761-14762 14765 14767-14770 14777 14779 14781 14818 14824-14825 14827 14917-14918 14923-14924 14929 14932-14934 14936 14938 14942 14958-14959 14962 14970 14973 15104 15106 15108 15114 15116 15122 15128 15136 15140 15142-15143 15150-15151 15158 15160 15172 15174 15178 15200https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/NatAs/6.367?format=asciiOpticaldefaultJ/other/NatAs/6.367/table2Fundamental stellar parameters inferred for the cool-giant host stars in our using an isochrone analysisSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
