cds-question@unistra.frmultiple-starssolar-system-planetsphotometryWe present photometry of four transits of the planetary system HAT-P-13, obtained using defocused telescopes. We analyse these, plus nine data sets from the literature, in order to determine the physical properties of the system. The mass and radius of the star are M_A_=1.320+/-0.048+/-0.039M_{sun}} and R_A_=1.756+/-0.043+/-0.017R_{sun}_ (statistical and systematic error bars). We find the equivalent quantities for the transiting planet to be M_b_=0.906+/-0.024+/-0.018M_Jup_ and R_b_=1.487+/-0.038+/-0.015R_Jup_, with an equilibrium temperature of T'_eq_=1725+/-31K. Compared to previous results, which were based on much sparser photometric data, we find the star to be more massive and evolved, and the planet to be larger, hotter and more rarefied.2012MNRAS.420.2580Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/420/2580CatalogResearchIsServedByTAP 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/AJ/141/179 : Transits of TrES-4b, HAT-P-3b and WASP-12b (Chan+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/420/2580https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/420/2580http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/420/2580https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/420/2580https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/420/2580http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/420/2580GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/MNRAS/420/2580/hatp13Defocussed photometry for transiting extrasolar planetary system HAT-P-13, Gunn i and Cousins I passbandsrecnoRecord number assigned by the VizieR team.
