cds-question@unistra.frexoplanetsinfrared-photometryvisible-astronomyphotometrybroad-band-photometryMany of the known hot Jupiters are formally unstable to tidal orbital decay. The only hot Jupiter for which orbital decay has been directly detected is WASP-12, for which transit-timing measurements spanning more than a decade have revealed that the orbital period is decreasing at a rate of dP/dt~10^-9^, corresponding to a reduced tidal quality factor of about 2x10^5^. Here, we present a compilation of transit-timing data for WASP-12 and 11 other systems that are especially favorable for detecting orbital decay: KELT-16; WASP-18, 19, 43, 72, 103, 114, and 122; HAT-P-23; HATS-18; and OGLE-TR-56. For most of these systems we present new data that extend the time baseline over which observations have been performed. None of the systems besides WASP-12 display convincing evidence for period changes, with typical upper limits on dP/dt on the order of 10^-9^ or 10^-10^, and lower limits on the reduced tidal quality factor on the order of 10^5^. One possible exception is WASP-19, which shows a statistically significant trend, although it may be a spurious effect of starspot activity.2020AJ....159..150Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/159/150CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/264 : ASAS Variable Stars in Southern hemisphere (Pojmanski+, 2005)J/ApJ/692/L9 : Tidal evolution of transiting exoplanets (Levrard+, 2009)J/ApJ/741/102 : 21 light curves of OGLE-TR-56b (Adams+, 2011)J/AJ/141/179 : Transits of TrES-4b, HAT-P-3b and WASP-12b (Chan+, 2011)J/A+A/529/A75 : Limb-darkening coefficients (Claret+, 2011)J/ApJ/742/116 : Photometry of 4 massive transiting exoplanets (Bakos+, 2011)J/ApJ/757/18 : RVs for 16 hot Jupiter host stars (Albrecht+, 2012)J/A+A/542/A4 : WASP-43b thirty eclipses (Gillon+, 2012)J/ApJ/757/161 : Spectroscopy of 56 exoplanet host stars (Torres+, 2012)J/A+A/552/A82 : WASP-64b and WASP-72b light curves (Gillon+, 2013)J/A+A/552/A2 : WASP-19b light curves (Lendl+, 2013)J/A+A/551/A108 : Multi-site obs. of WASP-12 b transit (Maciejewski+, 2013)J/MNRAS/436/2 : Transits of WASP-19b (Mancini+, 2013)J/A+A/558/A106 : Chemical abundances for 83 transit hosts (Mortier+, 2013)J/MNRAS/428/3671 : Transiting planet WASP-19b (Tregloan-Reed+, 2013)J/A+A/563/A40 : WASP-43b g'r'i'z'JHK light curves (Chen+, 2014)J/A+A/562/L3 : WASP-103b radial velocities and light curves (Gillon+, 2014)J/A+A/563/A41 : WASP-43 OSIRIS transmission spectroscopy (Murgas+, 2014)J/A+A/577/A54 : HAT-P23 and WASP-48 light curves (Ciceri+, 2015)J/PASP/127/143 : WASP-39b and WASP-43b light curves (Ricci+, 2015)J/MNRAS/447/711 : Transiting planet WASP-103 (Southworth+, 2015)J/AJ/151/17 : Eight transiting light curves of WASP-43b (Jiang+, 2016)J/A+A/588/L6 : WASP-12 transit light curves (Maciejewski+ 2016)J/AJ/152/127 : Sloan i follow-up light curves of HATS-18 (Penev+, 2016)J/A+A/606/A18 : WASP-103b light curves (Lendl+, 2017)J/AJ/154/4 : Times of transits and occultations of WASP-12b (Patra+,2017)J/AJ/153/136 : Planets & their host stars with Gaia plxs (Stassun+, 2017)J/AcA/68/371 : WASP and KELT planet transits (Maciejewski+, 2018)J/AJ/155/165 : Dissipation in exoplanet hosts (Penev+, 2018)J/AJ/157/43 : WASP-161b, WASP-163b and WASP-170b (Barkaoui+, 2019)J/AJ/157/217 : Transit times of 5 hot Jupiter WASP exoplanets (Bouma+,2019)J/AJ/157/235 : Observations of the Kepler field with TESS (Christ+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/159/150https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/159/150http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/159/150https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/159/150https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/159/150http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/159/150GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/159/150/table2 (Observation journal and measured mid-transit times)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/159/150/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/159/150/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/159/150/table2?GETtext/xml+votable180.050000true24.3543064-45.67788220.005555555555555556Cone search capability for table J/AJ/159/150/table3 (Transit times of all targets)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/159/150/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/159/150/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/159/150/table3?GETtext/xml+votable180.050000true306.123848116.76216940.0055555555555555566/12853 13250 19371 24409 24752 26771 28821 31541 35210 35993 38452https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/159/150?format=asciiOpticalInfrareddefaultJ/AJ/159/150/table2Observation journal and measured mid-transit timesrecnoRecord number assigned by the VizieR team.
