cds-question@unistra.freclipsing-binary-starssolar-system-planetsradial-velocityphotometryWe report the discovery of WASP-6b, an inflated sub-Jupiter mass planet transiting every 3.3610060^+0.0000022^_-0.0000035_days a mildly metal-poor solar-type star of magnitude V=11.9. A combined analysis of the WASP photometry, high-precision followup transit photometry and radial velocities yield a planetary mass M_p_=0.503^+0.019^_-0.038_ and radius R_p_=1.224^+0.051^_0.052_, resulting in a density {rho}_p_=0.27{+/-}0.05{rho}_J_. The mass and radius for the host star are M_*_=0.88^+0.05^-0.08_M_{sun}_ and R_*_=0.870^0.025^_-0.036_R_{sun}_. The non-zero orbital eccentricity e=0.054^+0.018^_-0.015_ that we measure suggests that the planet underwent a massive tidal heating ~1Gyr ago that could have contributed to its inflated radius. High-precision radial velocities obtained during a transit allow us to measure a sky-projected angle between the stellar spin and orbital axis {beta}=11^+14^_-18_{deg}. In addition to similar published measurements, this result favors a dominant migration mechanism based on tidal interactions with a protoplanetary disk.2009A&A...501..785Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/501/785CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/501/785https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/501/785http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/501/785https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/501/785https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/501/785http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/501/785GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/501/785/rise1WASP-6 deredenned and normalized differential photometry obtained by LT_RISE on 2008 July 25recnoRecord number assigned by the VizieR team.
