cds-question@unistra.frmultiple-starsexoplanetsWe determined new linear ephemerides of transiting exoplanets using long-cadence de-trended data from quarters Q1 to Q17 of Kepler mission. We analysed TTV diagrams of 2098 extrasolar planets. The TTVs of 121 objects were excluded (because of insufficient data-points, influence of stellar activity, etc). Finally, new linear ephemerides of 1977 exoplanets from Kepler archive are presented. The significant linear trend was observed on TTV diagrams of approximately 35% of studied exoplanets. Knowing correct linear ephemeris is principal for successful follow-up observations of transits. Residual TTV diagrams of 64 analysed exoplanets shows periodic variation, 43 of these TTV planets were not reported yet.2019RAA....19...41Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RAA/19.41CatalogResearchIsServedByTAP 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/RAA/19.41https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RAA/19.41http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RAA/19.41https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RAA/19.41https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RAA/19.41http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RAA/19.41GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RAA/19.41/table1 (Linear ephemerides)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/19.41/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/19.41/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/19.41/table1?GETtext/xml+votable180.050000true285.615408950.13575110.0055555555555555564/922-923 933-935 944-946 5/3645-3647 3704 3706 3730-3731 3789 3792 6/14567 14573 14578-14579 14730-14731 14733-14735 14744 14746 14749-14751 14792 14794-14795 14828 14830 14914-14915 14918-14919 15040-15041 15043-15045 15057 15060-15062 15153-15155 15160-15161 15172-15174 15178 15200 15232https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RAA/19.41?format=asciidefaultJ/other/RAA/19.41/table1Linear ephemeridesKICKepler Input Catalogmeta.idintrecnoRecord number assigned by the VizieR team.
