cds-question@unistra.frmultiple-starssolar-system-planetsphotometryWe present 10 new transit light curves of the transiting hot Jupiter HAT-P-13b, obtained during two observational seasons by three different telescopes. When combined with 12 previously published light curves, we have a sample consisting of 22 transit light curves, spanning 1041 days across four observational seasons. We use this sample to examine the recently observed large-amplitude transit timing variations (TTVs) by Pal et al. (2011MNRAS.413L..43P) and give refined system parameters. We find that the transit times are consistent with a linear ephemeris, with the exception of a single transit time, from UT 2009 November 5, for which the measured mid-transit time significantly deviates from our linear ephemeris. The nature of this deviation is not clear, and the rest of the data do not show any significant TTVs.2011AJ....142...84Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/142/84CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/707/446 : HAT-P-13 photometry follow-up (Bakos+, 2009)J/A+A/523/A84 : Transit light curves of HAT-P-13b (Szabo+, 2010)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/AJ/142/84https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/142/84http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/142/84https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/142/84https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/142/84http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/142/84GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/142/84/table1Photometry of HAT-P-13b obtained in this workrecnoRecord number assigned by the VizieR team.
