cds-question@unistra.frmultiple-starsexoplanetsphotometryWe study the transit timings of 10 exoplanets in order to investigate potential transit timing variations in them. We model their available ground-based light curves, some presented here and others taken from the literature, and homogeneously measure the mid-transit times. We statistically compare our results with published values and find that the measurement errors agree. However, in terms of recovering the possible frequencies, homogeneous sets can be found to be more useful, of which no statistically relevant example has been found for the planets in our study. We corrected the ephemeris information of all 10 planets we studied and provide these most precise light elements as references for future transit observations with space-borne and ground-based instruments. We found no evidence for secular or periodic changes in the orbital periods of the planets in our sample, including the ultra-short period WASP-103 b, whose orbit is expected to decay on an observable time-scale. Therefore, we derive the lower limits for the reduced tidal quality factors (Q) for the host stars based on best-fitting quadratic functions to their timing data. We also present a global model of all available data for WASP-74 b, which has a Gaia parallax-based distance value 25 per cent larger than the published value.2022MNRAS.512.2062Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/512/2062CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/512/2062https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/512/2062http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/512/2062https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/512/2062https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/512/2062http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/512/2062GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/512/2062/table4 (Reference ephemeris information (T0 and Porb))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/512/2062/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/512/2062/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/512/2062/table4?GETtext/xml+votable180.050000true306.123833316.76216670.0055555555555555566/2532 8825 12424 12853 15162 24057 25950 30013 31541 49103https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/512/2062?format=asciidefaultJ/MNRAS/512/2062/table3A log of photometric observations performed for this studyTelTelescopemeta.id;instr.telcharrecnoRecord number assigned by the VizieR team.
