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"]]
