cds-question@unistra.frmultiple-starssolar-system-planetsphotometryThe TASTE project is searching for low-mass planets with the transit timing variation (TTV) technique by gathering high-precision, short-cadence light curves for a selected sample of transiting exoplanets. It has been claimed that the "hot Jupiter" WASP-3b could be perturbed by a second planet. Presenting eleven new light curves (secured at the IAC80 and UDEM telescopes) and re-analyzing thirty-eight archival light curves in a homogeneous way, we show that new data do not confirm the previously claimed TTV signal. However, we bring evidence that measurements are not consistent with a constant orbital period, though no significant periodicity can be detected. Additional dynamical modeling and follow-up observations are planned to constrain the properties of the perturber or to put upper limits to it. We provide a refined ephemeris for WASP-3b and improved orbital/physical parameters. A contact eclipsing binary, serendipitously discovered among field stars, is reported here for the first time.2013A&A...549A..30Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/549/A30CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/527/A85 : Light curves of HAT-P-3b and HAT-P-14b (Nascimbeni+, 2011)J/A+A/532/A24 : Light curves of HAT-P-13b (Nascimbeni+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/549/A30https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/549/A30http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/549/A30https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/549/A30https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/549/A30http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/549/A30GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/549/A30/iac80Six light curves of WASP-3b (IAC-80)recnoRecord number assigned by the VizieR team.
