cds-question@unistra.frk-starsmultiple-starssolar-system-planetsphotometryWe report on the discovery of HAT-P-10b, one of the lowest mass (0.487+/-0.018M_J_) transiting extrasolar planets (TEPs) discovered to date by transit searches. HAT-P-10b orbits the moderately bright V=11.89 K dwarf GSC 02340-01714, with a period P=3.7224747+/-0.0000065d, transit epoch T_c_=2454759.68683+/-0.00016(BJD), and duration 0.1090+/-0.0008d. HAT-P-10b has a radius of 1.005^+0.032^_-0.027_R_J_ yielding a mean density of 0.594+/-0.052g/cm^3^. Comparing these observations with recent theoretical models we find that HAT-P-10b is consistent with a ~4.5Gyr, almost pure hydrogen and helium gas giant planet with a 10M_{earth}_ core. With an equilibrium temperature of T_eq_=1020+/-17K, HAT-P-10b is one of the coldest TEPs. Curiously, its Safronov number {Theta}=0.053+/-0.002 falls close to the dividing line between the two suggested TEP populations.2009ApJ...696.1950Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/696/1950CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/696/1950https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/696/1950http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/696/1950https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/696/1950https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/696/1950http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/696/1950GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/696/1950/table2Photometry follow-up of HAT-P-10recnoRecord number assigned by the VizieR team.
