Period changes in SuperWASP eclipsing binaries J/A+A/578/A136 ivo://CDS.VizieR/J/A+A/578/A136 doi:10.26093/cds/vizier.35780136 CDS Lohr M.E. Norton A.J. Payne S.G. West R.G. Wheatley P.J. 2017-10-13T15:41:59Z 2015-06-18T07:50:54Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr eclipsing-binary-stars variable-stars ccd-photometry Orbital period changes of binary stars may be caused by the presence of a third massive body in the system. Here we have searched the archive of the Wide Angle Search for Planets (SuperWASP) project for evidence of period variations in 13927 eclipsing binary candidates. Sinusoidal period changes, strongly suggestive of third bodies, were detected in 2% of cases; however, linear period changes were observed in a further 22% of systems. We argue on distributional grounds that the majority of these apparently linear changes are likely to reflect longer-term sinusoidal period variations caused by third bodies, and thus estimate a higher-order multiplicity fraction of 24% for SuperWASP binaries, in good agreement with other recent figures for the fraction of triple systems amongst binary stars in general. 2015A&A...578A.136L https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/578/A136 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/578/A136 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/578/A136 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/578/A136 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/578/A136 https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/578/A136 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/578/A136 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/A+A/578/A136/linear (SuperSWAP elcipsing binaries with linear period changes) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/578/A136/linear? https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/578/A136/linear? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/578/A136/linear?
