cds-question@unistra.frsolar-system-planetsmultiple-starsphotometryradial-velocityspectroscopyWe report the discovery of HAT-P-8b, a transiting planet with mass M_p_=1.52^+0.18^_-0.16_M_J_, radius R_p_=1.50^+0.08^_-0.06_R_J_, and photometric period P=3.076days. HAT-P-8b has a somewhat inflated radius for its mass, and a somewhat large mass for its period. The host star is a solar-metallicity F dwarf, with mass M_*_=1.28+/-0.04M_{sun}_ and R_*_=1.58^+0.08^_-0.06R_{sun}_. HAT-P-8b was initially identified as one of the 32 transiting-planet candidates in HATNet field G205. We describe the procedures that we have used to follow up these candidates with spectroscopic and photometric observations, and we present a status report on our interpretation for 28 of the candidates. Eight are eclipsing binaries with orbital solutions whose periods are consistent with their photometric ephemerides; two of these spectroscopic orbits are single-lined and six are double-lined.2009ApJ...704.1107Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/704/1107CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/141/166 : HATNet variability survey of K and M dwarfs (Hartman+, 2011)J/MNRAS/408/475 : HATNet Pleiades Rotation Period Catalogue (Hartman+, 2010)J/ApJ/663/573 : Sloan gi light curves of HAT-TR-205-012 (Beatty+, 2007)J/AJ/128/1761 : HATNET variability survey (Hartman+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/704/1107https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/704/1107http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/704/1107https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/704/1107https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/704/1107http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/704/1107GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/704/1107/htr205 (Candidates from HATNet field G205 sample and mean radial velocities estimates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/704/1107/htr205?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/704/1107/htr205?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/704/1107/htr205?GETtext/xml+votable180.050000true338.882539.8997220.0055555555555555566/13431 13437 13439 13522 13523 13525 13528 13532 13533 13535 13556 13559 13579 13601 13607 13615 13618 13626 13700 13702 13707 13716 13728 13729 13730https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/704/1107?format=asciiOpticaldefaultJ/ApJ/704/1107/htr205Candidates from HATNet field G205 sample and mean radial velocities estimateschi2? {chi}^2^stat.fit.chi2floatnullablerecnoRecord number assigned by the VizieR team.
