cds-question@unistra.frexoplanetsphotometryvisible-astronomyMany hot Jupiters may experience orbital decays, which are manifested as long-term transit-timing variations. We have analyzed 7068 transits from the Transiting Exoplanet Survey Satellite (TESS) for a sample of 326 hot Jupiters. These new mid-transit-time data allow us to update ephemerides for these systems. By combining the new TESS transit-timing data with archival data, we searched for possible long-term variations in the orbital period in these hot Jupiters using a linear and a quadratic ephemeris model. We identified 26 candidates that exhibit possible long-term variations of the orbital period, including 18 candidates with decreasing orbital periods and eight candidates with increasing orbital periods. Among them, 12 candidates failed our leave- one-out cross validation test and thus should be considered to be marginal candidates. In addition to tidal interaction, alternative mechanisms such as apsidal precession, the Romer effect, and the Applegate effect could also contribute to the variations during the observed period. The ephemerides derived in this work are useful for scheduling follow-up observations for these hot Jupiters in the future. The Python code (PdotQuest, http://github.com/AeoN400/PdotQuest) used to generate the ephemerides is made available online.2024ApJS..270...14Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/270/14CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)J/ApJ/640/1051 : 25pc sample of Sun-like stars (Grether+, 2006)J/AJ/133/1828 : Transit light curves of HD 189733 (Winn+, 2007)J/ApJ/657/1098 : Transit of TrES-1 (Winn+, 2007)J/ApJ/683/1076 : Transits of exoplanet XO-3b (Winn+, 2008)J/ApJ/696/1950 : Sloan iz light curves of HAT-P-10 (Bakos+, 2009)J/A+A/501/785 : Discovery and characterization of WASP-6b (Gillon+, 2009)J/ApJ/692/L9 : Tidal evolution of transiting exoplanets (Levrard+, 2009)J/A+A/508/1011 : Planetary transit of TrES-1 and TrES-2 (Rabus+, 2009)J/ApJ/691/1145 : Spectrophotometry of TrES-3 and TrES-4 (Sozzetti+, 2009)J/A+A/502/395 : WASP-11b (West+, 2009)J/AJ/137/3826 : Two transits of the giant planet WASP-4b (Winn+, 2009)J/ApJ/709/159 : Relative Ic photometry of WASP-17 (Anderson+, 2010)J/MNRAS/408/1494 : Planetary transits of TrES-2 and TrES-3 (Colon+, 2010)J/A+A/534/A16 : WASP-22 and WASP-26 phot. and velocities (Anderson+, 2011)J/ApJ/742/116 : Phot. of four massive transiting exoplanets (Bakos+, 2011)J/AJ/141/179 : Transits of TrES-4b, HAT-P-3b and WASP-12b (Chan+, 2011)J/ApJ/733/127 : Four transits of WASP-4b (Sanchis-Ojeda+, 2011)J/MNRAS/422/1988 : Three short-period, transiting exoplanets (Anderson+, 2012)J/AJ/144/19 : Follow-up phot. for HAT-P-34 through HAT-P-37 (Bakos+, 2012)J/MNRAS/426/739 : Velocities for 7 transiting hot Jupiters (Hellier+, 2012)J/A+A/539/A159 : WASP-4b transit griz light curves (Nikolov+, 2012)J/MNRAS/426/1338 : Transiting planetary system WASP-17 (Southworth+, 2012)J/A+A/558/A86 : HAT-P-42b and HAT-P-43b ri light curves (Boisse+, 2013)J/AJ/145/68 : Five new transit light curves of TrES-3 (Jiang+, 2013)J/ApJ/764/8 : APOSTLE r'-band transit LCs of TrES-3b (Kundurthy+, 2013)J/A+A/552/A2 : WASP-19b light curves (Lendl+, 2013)J/MNRAS/436/2 : Transits of WASP-19b (Mancini+, 2013)J/MNRAS/434/1300 : WASP-15 and WASP-16 light curves (Southworth+, 2013)J/MNRAS/428/3671 : Transiting planet WASP-19b (Tregloan-Reed+, 2013)J/A+A/551/A80 : WASP-80 photometric and radial velocity data (Triaud+, 2013)J/MNRAS/428/678 : Transiting exoplanet TrES-3b CCD UBVR phot.
