cds-question@unistra.frmultiple-starsexoplanetsphotometryWe present the results of our search for nearby planetary companions of transiting hot Jupiters in 12 planetary systems: HAT-P-24, HAT-P-39, HAT-P-42, HAT-P-50, KELT-2, KELT-15, KELT-17, WASP-23, WASP-63, WASP-76, WASP-79, and WASP-161. Our analysis was based on multi-sector time-series photometry from the Transiting Exoplanet Survey Satellite and precise transit timing data sets. We detected no additional transiting planets down to the 2-4 Earth radii regime. For ten hot Jupiters, no departure from linear transit ephemerides was observed. Whilst we refute long-term variations of the orbital period for WASP-161 b, which were claimed in the literature, we notice a tentative hint of the orbital period shortening for WASP-79 b. In addition, we spot a short-period transit timing variation for KELT-2A b with the characteristics typical of the so-called exomoon corridor. We conclude, however, that further observations are required to confirm these findings.2023AcA....73..159Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/73/159CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/725/2017 : Transiting planetary system HAT-P-24 (Kipping+, 2010)J/AJ/144/139 : Transiting planetary system HAT-P-39 (Hartman+, 2012)J/A+A/558/A86 : Transiting planetary system HAT-P-42 (Boisse+, 2013)J/AJ/150/168 : Transiting planetary system HAT-P-50 (Hartman+, 2015)J/ApJL/756/L39 : Transiting planetary system KELT-2A (Beatty+, 2012)J/AJ/151/138 : Transiting planetary system KELT-15 (Rodriguez+, 2016)J/AJ/152/136 : Transiting planetary system KELT-17 (Zhou+, 2016)J/A+A/531/A24 : Transiting planetary system WASP-23 (Triaud+, 2011)J/MNRAS/426/739 : Transiting planetary system WASP-63 (Hellier+, 2012)J/A+A/585/A126 : Transiting planetary system WASP-76A (West+, 2016)J/A+A/547/A61 : Transiting planetary system WASP-79 (Smalley+, 2012)J/AJ/157/43 : Transiting planetary system WASP-161 (Barkaoui+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/73/159https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/73/159http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/73/159https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/73/159https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/73/159http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/73/159GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/73/159/table1 (Observational properties of the systems of the sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/73/159/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/73/159/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/73/159/table1?GETtext/xml+votable180.050000true108.82514.2626110.0055555555555555566/4145 4632 17851 22396 22505 22519 24428 34708 39007 39487 39611 408641.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/73/159?format=asciidefaultJ/AcA/73/159/table1Observational properties of the systems of the sampleSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
