We find that the transit depth is greater and that the host star is more evolved than previously thought. The planet has a significantly larger radius (1.330 +/- 0.093 R(Jup) versus 0.915(-0.040)(+0.046) R(Jup)) and much lower density (0.41 +/- 0.10 rho(Jup) versus 1.26(-0.21)(+0.25) rho(Jup)) and surface gravity (13.4 +/- 2.6 ms(-2) versus 26.4(-4.0)(+4.4) ms(-2)) than previous measurements showed. Based on the revised properties it is no longer an outlier in planetary mass-radius and period-gravity diagrams. We also obtain a more precise transit ephemeris for the WASP-7 system."],["dc.identifier.doi","10.1051/0004-6361/201016183"],["dc.identifier.fs","590497"],["dc.identifier.isi","000287484100023"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/8600"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/23783"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Edp Sciences S A"],["dc.relation.issn","0004-6361"],["dc.relation.orgunit","Fakultät für Physik"],["dc.title","A much lower density for the transiting extrasolar planet WASP-7"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Our new data for WASP-15 comprise observations of one transit simultaneously in four optical passbands using GROND on the MPG/European Southern Observatory (ESO) 2.2 m telescope, plus coverage of half a transit from DFOSC on the Danish 1.54 m telescope, both at ESO La Silla. For WASP-16 we present observations of four complete transits, all from the Danish telescope. We use these new data to refine the measured physical properties and orbital ephemerides of the two systems. Whilst our results are close to the originally determined values for WASP-15, we find that the star and planet in the WASP-16 system are both larger and less massive than previously thought."],["dc.identifier.doi","10.1093/mnras/stt1089"],["dc.identifier.isi","000323638200026"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/28927"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Oxford Univ Press"],["dc.relation.issn","0035-8711"],["dc.title","High-precision photometry by telescope defocusing - V.
