Our three transit curves are modeled using the JKTEBOP code and adopting the quadratic limb-darkening law. Including our measurements, 18 transit times spanning about 4.2yr were used to determine the improved ephemeris with a transit epoch of 2454187.85560+/-0.00011BJD and an orbital period of 3.21305961+/-0.00000035days. The physical properties of the star-planet system are computed using empirical calibrations from eclipsing binary stars and stellar evolutionary models, combined with both our transit parameters and previously known spectroscopic results. We found that the absolute dimensions of the host star are M_A_=0.73+/-0.02M{sun}, R_A_=0.70+/-0.01R_{sun}_, log g_A_=4.61+/-0.02, p_A_=2.10+/-0.09{rho}{sun}, and L_A_=0.21+/-0.01L_{sun}_. The planetary companion has M_b_=0.21+/-0.01M_{Jup}_, R_b_=0.94+/-0.01R_{Jup}_, log g_b_=2.77+/-0.02, {rho}_b_=0.24+/-0.01{rho}_{Jup}_, and T_eq_=960+/-14K. Our results agree well with standard models of irradiated gas giants with a core mass of 11.3M_{earth}_.2012AJ....143...95Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/143/95CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/552/A119 : Planet-star and moon-planet interaction (Saur+, 2013)J/MNRAS/420/2580 : Four transits of HAT-P-13 (Southworth+, 2012)J/MNRAS/422/2024 : X-ray-age relation & exoplanet evaporation (Jackson+, 2012)J/MNRAS/411/L46 : Exoplanet magnetic fields (Vidotto+, 2011)J/PASP/123/412 : Exoplanet Orbit Database (Wright+, 2011)J/A+A/532/A24 : Light curves of HAT-P-13b (Nascimbeni+, 2011)J/AJ/142/84 : 10 new transit light curves of HAT-P-13b (Fulton+, 2011)J/A+A/527/A85 : Light curves of HAT-P-3b and HAT-P-14b (Nascimbeni+, 2011)J/MNRAS/414/1278 : Eccentricities of transiting planets (Pont+, 2011)J/ApJ/726/52 : HAT-P-18 and HAT-P-19 follow-up (Hartman+, 2011)J/A+A/523/A84 : Transit light curves of HAT-P-13b (Szabo+, 2010)J/ApJ/716/1336 : Stability analysis of single-planet (Kopparapu+, 2010)J/ApJ/706/785 : HAT-P-12 light curve (Hartman+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/143/95https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/143/95http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/143/95https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/143/95https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/143/95http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/143/95GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfraredOpticaldefaultJ/AJ/143/95/table2Rc-band photometry of HAT-P-12recnoRecord number assigned by the VizieR team.
