cds-question@unistra.frsolar-system-planetsmultiple-starsphotometryradial-velocityf-starsdwarf-starsWe report the discovery of HAT-P-56b by the HATNet survey, an inflated hot Jupiter transiting a bright F-type star in Field 0 of NASA's K2 mission. We combine ground-based discovery and follow-up light curves with high precision photometry from K2, as well as ground-based radial velocities from the Tillinghast Reflector Echelle Spectrograph on the Fred Lawrence Whipple Observatory 1.5m telescope to determine the physical properties of this system. HAT-P-56b has a mass of 2.18M_J_, radius of 1.47R_J_, and transits its host star on a near-grazing orbit with a period of 2.7908day. The radius of HAT-P-56b is among the largest known for a planet with M_P_>2M_J_. The host star has a V-band magnitude of 10.9, mass of 1.30M_{sun}_, and radius of 1.43R_{sun}_. The periodogram of the K2 light curve suggests that the star is a {gamma} Dor variable. HAT-P-56b is an example of a ground-based discovery of a transiting planet, where space-based observations greatly improve the confidence in the confirmation of its planetary nature, and also improve the accuracy of the planetary parameters.2015AJ....150...85Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/150/85CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/149/149 : Photometry and spectroscopy of HAT-P-54 (Bakos+, 2015)J/AJ/147/84 : Photometry and spectroscopy of HAT-P-49 (Bieryla+, 2014)J/MNRAS/429/2001 : New transiting planet candidates from Kepler (Huang+, 2013)J/AJ/144/139 : HAT-P-39, HAT-P-40, and HAT-P-41 follow-up (Hartman+, 2012)J/ApJ/734/109 : Follow-up photometry of HAT-P-27 (Beky+, 2011)J/ApJ/720/1118 : i-band photometry of HAT-P-16 (Buchhave+, 2010)J/ApJ/710/1724 : Follow-up photometry for HAT-P-11 (Bakos+, 2010)http://hatnet.org/ : HATNet websitehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/150/85https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/150/85http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/150/85https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/150/85https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/150/85http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/150/85GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/AJ/150/85/table2Relative radial velocities, and bisector span measurements of HAT-P-56recnoRecord number assigned by the VizieR team.
