cds-question@unistra.frmultiple-starsphotometrysolar-system-planetsWe present new spectroscopic and photometric observations of the transiting exoplanetary system WASP-3. Spectra obtained during two separate transits exhibit the Rossiter-McLaughlin (RM) effect and allow us to estimate the sky-projected angle between the planetary orbital axis and the stellar rotation axis, {lambda}=3.3^+2.5^_-4.4_deg. This alignment between the axes suggests that WASP-3b has a low orbital inclination relative to the equatorial plane of its parent star. During our first night of spectroscopic measurements, we observed an unexpected redshift briefly exceeding the expected sum of the orbital and RM velocities by 140m/s. This anomaly could represent the occultation of material erupting from the stellar photosphere, although it is more likely to be an artifact caused by moonlight scattered into the spectrograph.2010ApJ...715..421Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/715/421CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/692/L9 : Tidal evolution of transiting extrasolar planets (Levrard+,J/PASP/120/1128 : Calibrated griz magnitudes of Tycho star (Ofek, 2008)J/MNRAS/379/816 : SuperWASP-North extrasolar planet candidates (Street+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/715/421https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/715/421http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/715/421https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/715/421https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/715/421http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/715/421GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/715/421/table1Relative photometry of WASP-3recnoRecord number assigned by the VizieR team.
