cds-question@unistra.frexoplanetsphotometryvisible-astronomyastronomical-reference-materialsThe ExoClock project has been created to increase the efficiency of the Ariel mission. It will achieve this by continuously monitoring and updating the ephemerides of Ariel candidates, in order to produce a consistent catalog of reliable and precise ephemerides. This work presents a homogenous catalog of updated ephemerides for 450 planets, generated by the integration of ~18000 data points from multiple sources. These sources include observations from ground-based telescopes (the ExoClock network and the Exoplanet Transit Database), midtime values from the literature, and light curves from space telescopes (Kepler, K2, and TESS). With all the above, we manage to collect observations for half of the postdiscovery years (median), with data that have a median uncertainty less than 1 minute. In comparison with the literature, the ephemerides generated by the project are more precise and less biased. More than 40% of the initial literature ephemerides had to be updated to reach the goals of the project, as they were either of low precision or drifting. Moreover, the integrated approach of the project enables both the monitoring of the majority of the Ariel candidates (95%), and also the identification of missing data. These results highlight the need for continuous monitoring to increase the observing coverage of the candidate planets. Finally, the extended observing coverage of planets allows us to detect trends (transit-timing variations) for a sample of 19 planets.2023ApJS..265....4Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/265/4CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/34 : K2 Ecliptic Plane Input Catalog (EPIC) (Huber+, 2017)IV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)J/ApJ/652/1715 : Four transits of the exoplanet XO-1b (Holman+, 2006)J/ApJ/704/1107 : Transiting planet cand. in HATNet field 205 (Latham+, 2009)J/ApJ/742/116 : Phot. of four massive transiting exoplanets (Bakos+, 2011)J/ApJ/736/19 : Kepler planetary candidates.
