cds-question@unistra.freclipsing-binary-starssolar-system-planetsradial-velocityphotometryWe report on spectroscopic and photometric observations through transits of the exoplanets WASP-22b and WASP-26b, intended to determine the systems' spin-orbit angles. We combine these data with existing data to refine the system parameters. We measure a sky-projected spin-orbit angle of 22+/-16 degrees for WASP-22b, showing the planet's orbit to be prograde and, perhaps, slightly misaligned. We do not detect the Rossiter-McLaughlin effect of WASP-26b due to its low amplitude and observation noise. We place 3-sigma upper limits on orbital eccentricity of 0.063 for WASP-22b and 0.050 for WASP-26b. After refining the drift in the systemic velocity of WASP-22 found by Maxted et al. (2010AJ....140.2007M), we find the third body in the system to have a separation-scaled minimum-mass of 5.3+/-0.3M_Jup_ (a3/5AU)^2^, where a3 is the orbital separation of the third body.2011A&A...534A..16Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/534/A16CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/MNRAS/408/1680 : Transiting planetary system WASP-2 (Southworth+, 2010)J/MNRAS/399/287 : Transiting planetary system WASP-4 (Southworth+, 2009)J/A+A/530/A5 : WASP-4b Ks-band thermal emission detection (Caceres+, 2011)J/AJ/137/3826 : Two transits of the giant planet WASP-4b (Winn+, 2009)J/MNRAS/396/1023 : Transiting planetary system WASP-5 (Southworth+, 2009)J/A+A/501/785 : Discovery and characterization of WASP-6b (Gillon+, 2009)J/A+A/527/A8 : Transiting planetary system WASP-7 (Southworth+, 2011)J/A+A/517/L1 : Radial velocities of WASP-8b planet (Queloz+, 2010)J/ApJ/692/L100 : Relative photometry of WASP-10 (Johnson+, 2009)J/A+A/528/A65 : WASP-12b transits (Maciejewski+, 2011)J/A+A/502/391 : WASP-13b photometry and radial velocities (Skillen+, 2009)J/ApJ/707/167 : Transiting planetary system WASP-18 (Southworth+, 2009)J/A+A/513/L3 : WASP-19b H-band thermal emission (Anderson+, 2010)J/A+A/519/A98 : Transit of exoplanet WASP-21b (Bouchy+, 2010)J/A+A/520/A56 : WASP-26b RV and photometric data (Smalley+, 2010)J/A+A/526/L10 : Transits of WASP-33 (Herrero+, 2011)J/A+A/526/A130 : WASP-34b photometry and radial velocities (Smalley+, 2011)J/A+A/525/A54 : Transits of WASP-38b (Barros+, 2011)J/A+A/531/A24 : WASP-23 photometric and radial velocity data (Triaud+ 2011)J/A+A/531/A40 : Transits of WASP-39b (Faedi+, 2011)J/A+A/531/A60 : WASP-31b photometry and radial velocities (Anderson+, 2011)J/A+A/533/A88 : WASP-50b photometry and radial velocities (Gillon+, 2011)J/A+A/524/A25 : Radial Velocities on 6 exoplanet host stars (Triaud+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/534/A16https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/534/A16http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/534/A16https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/534/A16https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/534/A16http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/534/A16GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/534/A16/phot*WASP-22 and WASP-26 dereddened and normalised differential photometry from TRAPPIST, Euler and OverskyrecnoRecord number assigned by the VizieR team.
