cds-question@unistra.frmultiple-starssolar-system-planetsphotometryTASTE (The Asiago Search for Transit timing variations of Exoplanets) project is collecting high-precision, short-cadence light curves for a selected sample of transiting exoplanets. It has been claimed that the hot jupiter HAT-P-13b suddenly deviated from a linear ephemeris by ~20min, implying that there is a perturber in the system. Using five new transits, we discuss the plausibility of this transit time variation (TTV), and show that a periodic signal should not be excluded. More follow-up observations are required to constrain the mass and the orbit of the hypothetical perturber.2011A&A...532A..24Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/532/A24CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/527/A85 : Light curves of HAT-P-3b and HAT-P-14b (Nascimbeni+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/532/A24https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/532/A24http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/532/A24https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/532/A24https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/532/A24http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/532/A24GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/532/A24/hat13Five light curves of HAT-P-13brecnoRecord number assigned by the VizieR team.
