cds-question@unistra.frphotometrymultiple-starssolar-system-planetsWe report the discovery of HAT-P-16b, a transiting extrasolar planet orbiting the V=10.8mag F8 dwarf GSC 2792-01700, with a period P=2.775960+/-0.000003 days, transit epoch T_c_=2455027.59293+/-0.00031 (BJD10), and transit duration 0.1276+/-0.0013 days. The host star has a mass of 1.22+/-0.04M_{sun}_, radius of 1.24+/-0.05R_{sun}_, effective temperature 6158+/-80K, and metallicity [Fe/H]=+0.17+/-0.08. The planetary companion has a mass of 4.193+/-0.094M_J_ and radius of 1.289+/-0.066R_J_, yielding a mean density of 2.42+/-0.35g/cm^3^. Comparing these observed characteristics with recent theoretical models, we find that HAT-P-16b is consistent with a 1Gyr H/He-dominated gas giant planet. HAT-P-16b resides in a sparsely populated region of the mass-radius diagram and has a non-zero eccentricity of e=0.036 with a significance of 10{sigma}.2010ApJ...720.1118Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/720/1118CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/MNRAS/422/2024 : X-ray-age relation and exoplanet evaporation (Jackson+,J/MNRAS/414/1278 : Eccentricities of transiting planets (Pont+, 2011)J/MNRAS/411/L46 : Exoplanet magnetic fields (Vidotto+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/720/1118https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/720/1118http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/720/1118https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/720/1118https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/720/1118http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/720/1118GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/720/1118/table2Follow-up photometry of HAT-P-16BJDBarycentric Julian Datedtime.epochdoublerecnoRecord number assigned by the VizieR team.
