cds-question@unistra.frinfrared-photometryvisible-astronomybroad-band-photometrysolar-system-planetsradial-velocitymultiple-starsWe report the discovery of two exoplanets transiting high-jitter stars. HAT-P-32b orbits the bright V=11.289 late-F-early-G dwarf star GSC 3281-00800, with a period P=2.150008+/-0.000001d. The stellar and planetary masses and radii depend on the eccentricity of the system, which is poorly constrained due to the high-velocity jitter (~80m/s). Assuming a circular orbit, the star has a mass of 1.16+/-0.04M_{sun}_ and radius of 1.22+/-0.02R_{sun}_, while the planet has a mass of 0.860+/-0.164M_J_ and a radius of 1.789+/-0.025R_J_. The second planet, HAT-P-33b, orbits the bright V=11.188 late-F dwarf star GSC 2461-00988, with a period P=3.474474+/-0.000001d. As for HAT-P-32, the stellar and planetary masses and radii of HAT-P-33 depend on the eccentricity, which is poorly constrained due to the high jitter (~50m/s). In this case, spectral line bisector spans (BSs) are significantly anti-correlated with the radial velocity residuals, and we are able to use this correlation to reduce the residual rms to ~35m/s. We find that the star has a mass of 1.38+/-0.04M_{sun}_ and a radius of 1.64+/-0.03R_{sun}_ while the planet has a mass of 0.762+/-0.101M_J_ and a radius of 1.686+/-0.045R_J_ for an assumed circular orbit. Due to the large BS variations exhibited by both stars we rely on detailed modeling of the photometric light curves to rule out blend scenarios. Both planets are among the largest radii transiting planets discovered to date.2011ApJ...742...59Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/742/59CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/311 : WISE All-Sky Data Release (Cutri+ 2012)VI/135 : All-sky spectrally matched Tycho2 stars (Pickles+, 2010)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/A+A/552/A119 : Planet-star and moon-planet interaction (Saur+, 2013)J/MNRAS/422/2024 : X-ray-age relation & exoplanet evaporation (Jackson+, 2012)J/PASP/123/412 : Exoplanet Orbit Database (Wright+, 2011)J/ApJ/734/109 : Follow-up photometry of HAT-P-27 (Beky+, 2011)J/ApJ/728/138 : Follow-up photometry of HAT-P-26 (Hartman+, 2011)J/ApJ/726/52 : HAT-P-18 and HAT-P-19 follow-up (Hartman+, 2011)J/ApJ/725/875 : Chromospheric activity for CPS stars (Isaacson+, 2010)J/ApJ/724/866 : Follow-up observations of HAT-P-15 (Kovacs+, 2010)J/ApJ/715/458 : Differential photometry of HAT-P-14 (Torres+, 2010)J/ApJ/710/1724 : Follow-up photometry for HAT-P-11 (Bakos+, 2010)J/ApJ/707/446 : HAT-P-13 photometry follow-up (Bakos+, 2009)J/ApJ/706/785 : HAT-P-12 light curve (Hartman+, 2009)J/ApJ/696/1950 : Sloan iz light curves of HAT-P-10 (Bakos+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/742/59https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/742/59http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/742/59https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/742/59https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/742/59http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/742/59GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/ApJ/742/59/table3Relative radial velocities, bisector spans, and activity index measurements of HAT-P-32recnoRecord number assigned by the VizieR team.
