cds-question@unistra.frmultiple-starssolar-system-planetsapparent-magnitudeWe present the first results from a speckle imaging survey of stars classified as candidate exoplanet host stars discovered by the Kepler mission. We use speckle imaging to search for faint companions or closely aligned background stars that could contribute flux to the Kepler light curves of their brighter neighbors. Background stars are expected to contribute significantly to the pool of false positive candidate transiting exoplanets discovered by the Kepler mission, especially in the case that the faint neighbors are eclipsing binary stars. Here, we describe our Kepler follow-up observing program, the speckle imaging camera used, our data reduction, and astrometric and photometric performance. Kepler stars range from R=8 to 16 and our observations attempt to provide background non-detection limits 5-6mag fainter and binary separations of ~0.05-2.0-arcsec. We present data describing the relative brightness, separation, and position angles for secondary sources, as well as relative plate limits for non-detection of faint nearby stars around each of 156 target stars. Faint neighbors were found near 10 of the stars.2011AJ....142...19Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/142/19CatalogResearchIsServedByTAP 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/AJ/142/19https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/142/19http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/142/19https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/142/19https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/142/19http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/142/19GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/142/19/table1 (Kepler speckle targets lacking detectable secondaries)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/142/19/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/142/19/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/142/19/table1?GETtext/xml+votable180.050000true294.3565438.947380.005555555555555556Cone search capability for table J/AJ/142/19/table2 (Kepler speckle targets with detected secondaries)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/142/19/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/142/19/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/142/19/table2?GETtext/xml+votable180.050000true286.9711946.868358890.0055555555555555565/3731 3734 3742 6/14573 14578 14579 14581 14584 14585 14586 14591 14730 14731 14734 14735 14744 14746 14751 14755 14757 14759 14760 14762 14764 14765 14768 14770 14771 14772 14773 14774 14779 14782 14783 14794 14816 14817 14825 14826 14827 14828 14830 14918 14919 14920 14921 14929 14930 14932 14933 14940 14943 14945 14947 14950 14953 14955 14957 14959 14961 14972 14973 14975 15040 15045 15060 15104 15107 15109 15110 15111 15112 15113 15118 15119 15120 15121 15130 15131 15134 15139 15140 15145 15147 15149 15150 15151 15153 15155 15157 15158 15160 15168 15169 15171 15172https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/142/19?format=asciidefaultJ/AJ/142/19/table1Kepler speckle targets lacking detectable secondariesrecnoRecord number assigned by the VizieR team.
