cds-question@unistra.frmultiple-starssolar-system-planetsinfrared-photometryvisible-astronomyphotometryFive newly observed transit light curves of the TrES-3 planetary system are presented. Together with other light-curve data from the literature, 23 transit light curves in total, which cover an overall timescale of 911 epochs, have been analyzed through a standard procedure. From these observational data, the system's orbital parameters are determined and possible transit timing variations (TTVs) are investigated. Given that a null TTV produces a fit with reduced {chi}^2^=1.52, our results agree with previous work, that TTVs might not exist in these data. However, a one-frequency oscillating TTV model, giving a fit with a reduced {chi}^2^=0.93, does possess a statistically higher probability. It is thus concluded that future observations and dynamical simulations for this planetary system will be very important.2013AJ....145...68Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/145/68CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/142/84 : 10 new transit light curves of HAT-P-13b (Fulton+, 2011)J/MNRAS/408/1494 : Planetary transits of TrES-2 and TrES-3 (Colon+, 2010)J/ApJ/691/1145 : Spectrophotometry of TrES-3 and TrES-4 (Sozzetti+, 2009)J/AJ/137/3826 : Two transits of the giant planet WASP-4b (Winn+, 2009)J/AJ/136/267 : Six occultations of the exoplanet TrES-3 (Winn+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/145/68https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/145/68http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/145/68https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/145/68https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/145/68http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/145/68GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/AJ/145/68/table6The photometric light-curve datarecnoRecord number assigned by the VizieR team.
